• Transformer grounding connections,
• Make sure that transformer secondary power circuit protective shield connections are made according to recommendations (both ends connected to ground),
• The transformer frame must be connected to the protective grounding system,
• Interface cabling between the transformer and the ACS 1000.
3.3. Converter Room
When inspecting the converter room, attention must be paid to the following:
• Building work must be finished in the converter room.
• The converter room must be clean (free of dust) and dry.
• Air filters must be in place.
• Air conditioning must be available latest when the converter will be operated continuously.
If the condition of the converter room hampers effective commissiong, the customer and the responsible ABB project engineer must be informed immediately.
Cleanness of the converter room should be checked several times during commissioning.
www.PLCworld.cn
www.91HMI.com
www.PLCworld.cn
3.4. Converter
The inspection includes the mechanical and electrical installation of the converter. By visually checking the converter, the commissioning engineer obtains an overview of the condition of the converter and can react in time if corrections have to be made.
Useful information on the requirements for the installation site is written in the User’s Manual of the converter, Chapter 3 - Mechanical Installation and Appendix C – Mechanical Drawings.
If the installation of the converter has not been carried out as required or the condition of the converter hampers effective commissiong, the customer and the responsible ABB project engineer must be informed immediately.
When inspecting the converter, the checklist below can be used as a guide. Depending on the configuration of the converter and applicable options, there might be less or more check items. Always see supplied parts list, mechanical and electrical drawings for reference.
Check List
• Installation and damages of components.
• Cable openings should be closed to avoid dust entering into the cabinets.
• Foreign parts, dust and moisture must not be present in the converter cabinets.
It is very important that there is no dust and moisture inside the cabinets. Dust and moisture weaken the busbar insulation. Dust tends to build up on air-cooling elements, thus impairing cooling.
• Converter doors must open and close easily.
If the doors cannot be opened and closed properly, the alignment of the converter must be checked and corrected.
• Floor fixings must be mounted.
The mounting holes are indicated in Appendix C- Layout Drawing in the User’s Manual of the converter.
• Cooling water connections must be made.
Information on the flange sizes or project specific features are shown in Appendix C- Layout Drawing in the User’s Manual of the converter.
• Termination and routing of power cables.
All cable connections between converter and transformer and between converter and motor are shown in Appendix D – Electrical Drawings in the User’s Manual of the converter. Project specific cable entries are indicated in Appendix C – Mechanical Drawings in the

Chapter 3 - Inspection of Installation
ABB
IMPORTANT!
Power cables must not be connected at the converter before the insulation resistance of the converter and the motor have been measured.
3.5. Ground Connections
Ground connections must be carried out carefully to prevent that high potentials will occur in any parts, which can be touched easily.
Inspection of ground connections includes the following:
• The converter must be connected to the ground system of the factory (system ground).
• The shields of all power cables must be connected to the ground busbar.
• The cross section of the cable shields must be in accordance with the Power Cable Specification.
3.6. Motor
The motor area must be cleaned so that it is safe to run the motor. All waste that can come in contact with the shaft or the cooling air inlets must be removed.
The motor installation includes the piping of lubrication and water-cooling system and the alignment of the motor. An alignment protocol must be available on site.
The motor frame must be connected to the ground network of the plant.

Do not switch on a cooling pump if the cooling circuit is empty. If a pump runs dry, the pump seals will be immediately damaged.
Check that the installation is made as described in chapter 2 – Installation in the WCU Operation and Maintenance Manual.
Check especially:
• Connection of raw water hoses / pipes.
• Direction of raw water flow.
• Requirements for the raw water (temperature, flow, pressure etc.).
• Leakage water connection.
• For bent hoses and visible damages in the internal cooling circuit.
NOTICE!
Especially the hoses on the sinus filter choke can easily be bent during the installation, see Figure 6-1).

• Cleanness of the strainer Z1.
This should be checked again after some days of operation because during the first time of water flow possible loose particles and dirt from the water pipes should be flushed out and caught in the strainer.
6.1.2. Filling Up the Internal Cooling Circuit
Fill the internal cooling circuit according to the instructions in chapter 3 – Starting up the Cooling System in the WCU Operation and Maintenance Manual.
After filling up the internal cooling circuit, remember to:
• Vent (deaerate) the internal cooling pumps.
• Check the direction of internal water flow (check the direction of rotation of the pumps).
• Check the direction of rotation of the auxiliary cooling fans.
• Check the water level in the expansion vessel.
6.1.3. Functional Test of the Redundant Fan
In case the converter is equipped with redundant cooling fans, check the function according to the instruction below.
1 Start pump number 1, fan number 1 (standard fan inside cabinet) starts rotating, the air-flaps under the redundant fan should be closed and the air flaps under the internal fan should open.
2 Feel the air flow (how strong does the fan blow).
3 Switch off the motor circuit breaker of the standard fan, the redundant fan starts rotating, the air flaps under the redundant fan should open and the air flaps under the internal fan should close.
4 Feel the air flow of redundant fan, it should blow as strong as fan number 1.
5 In case the air flow is much weaker you have to change the direction of rotation of the redundant fan.
6.2. Air-Cooled ACS 1000 and ACS 1000i
• Check that the air exhaust box on top of the converter is assembled according to the instructions (ACS 1000i: N.A.).
• Check that all applicable fans installed on top of the converter are installed (only ACS 1000i).
• Check that the fan(s) are rotating smoothly and in the right direction.
• In case of redundant fans check that the installation of the fan box is made according to the instructions.

Chapter 7 - Insulation Resistance Measurements
Before any of the components in the drive system can be energized, it must be assured that they are able to withstand the voltage stress. This can be verified by measuring the insulation resistance. If the measured insulation resistance value of the motor, transformer or converter is too low, the reason may be that insulators, windings etc. have moisture in them and it may be necessary to dry the windings.
It is advisable to compare the test results with the test reports from the supply factories.
The contractor or customer can make the insulation resistance
measurements on the supply transformer, cables and motor, in that case a signed test-protocol of all measurements must be attached to the commissioning report. A certified commissioning engineer must always make the insulation resistance measurement test on the ACS 1000.
7.1. Preparations
• Make sure that the Main Circuit Breaker is locked in test position (ACS 1000i: make sure that the external supply breaker is locked in test position).
• Disconnect the cables between the supply transformer and the converter and isolate them from ground and the frames of the transformer and the converter (ACS 1000i: disconnect the supply cables and isolate them from ground and the frames of the supply breaker and the converter).
• Disconnect the cables between the converter and the motor and isolate them from ground and the frames of the converter and the motor.
7.2. External MCB
The main circuit breaker is commissioned and the insulation tests are performed according to the documentation of the manufacturer. The signed MCB commissioning report must be received from the responsible person.

Chapter 7 - Insulation Resistance Measurements
ABB
7.3. Internal MCB (only ACS 1000i)
All poles should be meggered against each other and against ground.
The absolute value depends on other equipment connected to the breaker but it should be higher than 1 MΩ per 1 kV.
7.4. Transformer
The following procedure should be used for checking the insulation resistance measurement of the supply transformer (ACS 1000i: The internal transformer is tested together with the converter and it is not necessary to test it separately).
1 Short circuit all windings individually (HV, LV1 and LV2
andadditionally LV3 and LV4 in case of a 24-pulse transformer).
2 Connect all other windings than the one to be measured to ground (see Figure 7-1).

3 Connect the megger between the winding to be measured and ground, the test voltage is 5 kVDC for 60 seconds.
www.PLCworld.cn
www.91HMI.com
www.PLCworld.cn
4 Repeat the measurement for the other windings, all individual windings should be measured against ground, the following measurements are needed:
• HV – T/E,
• LV1 – T/E,
• LV2 – T/E,
• LV3 – T/E (in case of 24-pulse transformer),
• LV4 – T/E (in case of 24-pulse transformer).
The insulation resistance should normally be several thousand MΩ, the value is however depending on temperature of the transformer. For verification of the actual values to the values during normal conditions (20°C) the following conversion table is valid.

The test voltage should be 5000 VDC for 60 seconds. The measured insulation resistance must be higher than 10 Mohm in a water-cooled ACS 1000 and higher than 100 Mohm in an air-cooled ACS1000. In the water-cooled ACS 1000, the result is depending on the actual water conductivity of internal cooling water, if the conductivity is below 0,3 uS it is normally possible to get an acceptable result.

7.7. Motor
1 The frame and the windings not being tested must be grounded during the insulation resistance measurement.
2 All resistance temperature detectors (RTD) must be grounded.
The insulation resistance of new motor is normally very high. A thumb rule can be that if the measured value is one decade or more lower than the value measured in the factory, check the winding for excess moisture or dirt. The test report contains the insulation resistance value measured in the factory.
If the motor star point is reachable, measure each phase separately as shown in Figure 7-6.

Chapter 8 - Preparing the System
Before the drive system components can be energized they must be checked and prepared for switching on the main voltage. When
inspecting each of the system components, follow the instructions given in the documentation for each of the components.
8.1. MCB and Protection Relay
Protection relays in the feeding switchgear must be tested, especially the relays of the converter transformer. The setting of these relays must be checked and compared with the project specific values. Relay test protocols must be available on site.
The correct operation of the MCB will be tested before the MCB is used to supply the main power to the converter. The test is performed with the main power supply disconnected from the MCB.
Information on the required control interface to the converter and on the breaking time of the circuit breaker can be obtained from the Main Circuit Breaker Specification and the Main Circuit Breaker Application Note.
• Check that the operational mechanisms of the MCB are working properly (WITHOUT MEDIUM VOLTAGE SUPPLY).
• Check that the MCB interlocking and locking facilities are working properly.
• Check that the MCB can be racked out properly.
• Check that the MCB cannot be operated locally.
8.2. Transformer
All checks and insulation measurements of transformers must be
performed according to the instructions of the transformer manufacturer.
Checking of the transformer includes the following:
• Rating plate values must correspond to the project data,
• Cleanness of transformer room and equipment,
• Thermal protective devices and other external measurement and protection devices,
• Oil quantity, in case of oil type transformer,
Oil quantity can be checked on the oil level gauge located on the oil

ABB
• Valves between transformer tank and radiator,
All valves must be in open position to allow free oil flow between tank and radiators,
• Condition of dehydrating breathers,
• Sense of rotation of fans and pumps (if applicable).
IMPORTANT!
The protectice devices from the supply transformer can be connected either to the ACS 1000 or to some other protection device. If they are not conncted to the ACS 1000, it is recommended to connect one common “Transformer trip signal” to the ACS 1000 tripping loop, connectors X300:7 and X300:8.
8.3. Converter
8.3.1. Standard Hardware
The following things must be checked before the ACS 1000 can be energized.
• Visually all medium voltage connections (busbars and cables).
• Visually all auxiliary supply cables.
• Visually all fibre optic cables.
• In case of water cooled ACS 1000, the centre post in font of the inverter must be installed (see Figure 7-3).
• In case of a water-cooled ACS 1000, the shipping brackets securing the swing frame must be removed.
• All semiconductors (IGCT’s and diodes) in the rectifier and the inverter must be measured with a Multimeter.
• The DIP-switches for configuring the analogue inputs are correct set (each IOEC-board has it’s own set of dip-switches).
All analogue inputs can be set to current or voltage range with dip switches (2 switches / analogue input), see Figure 8-1 and Figure 8-2.

8.3.3. Customer Parameters
Set all customer specific parameters. For more information see the Signal and Parameter table.
IMPORTANT!
Different software-versions may have different parameters.
8.3.4. Motor Parameters in Group 99 And 112
• Calculate the motor parameters with the mot_par-Excel-table, either with the name plate data of the motor (see Figure 8-5) or with the equivalent circuit of the motor (see Figure 8-6).
To ensure that the motor parameters are calculated correctly, the mot_par-table from the loading package of the used software must be used.
• Check that the filter capacitance specified with the type code (cell B45) corresponds with the filter capacitance value in parameter 6.15 FilterCapacity and with the installed sine filter capacitance in the converter (check the name plates of the installed capacitors).
• Check that the filter inductance specified with the type code (cell B46) corresponds with the filter inductance value in parameter 6.14 FilterInductance and with the installed sine filter choke in the converter (check the name plate of the installed choke).
• Check that the filter resonance frequency (cell E70) is less than 380 Hz.
www.PLCworld.cn
www.91HMI.com
www.PLCworld.cn
If the calculated resonance frequency is higher than 380 Hz, check that the entered motor data and the entered sine filter inductance and capacitance are correct, if the calculated sine filter resonance
frequency is still too high, the sine filter configuration must be changed.
• Set the correct motor parameters in group 99.
• Set the correct motor parameters calculated with the mot_par-Excel- table in group 112, the group can be opened with the password 564.
IMPORTANT!
The sine filter damping parameters in group 112 (older software
versions) or group 115 (newer software versions) must not be modified, they are automatically set to the correct values by the software loading package.

The test can be made according to the following procedure:
1 Make sure the MCB is in test-position.
2 Set all appropriate parameters for the MCB Control.
• 21.06 MCB On Control Mode
• 21.07 MCB Feedback Signal
• 21.08 MCB Available Signal
• 21.09 MCB Closing Time Lim
• 21.10 MCB Opening Time Lim
3 In case the MCB Available-function is enabled, check that the feedback-signals is correct (i.e. the MCB Not Available-alarm is activated when the MCB is in test-position).
IMPORTANT!
If the MCB Available-function is enabled, it is only possible to operate the grounding-switch when the MCB is in test-position i.e. when the MCB Not Available-alarm is active.
4 Temporary disable the MCB Available-function (set parameter 21.08 MCB Available Signal to ‘No’).
5 Set the drive to local control.
6 Reset all faults in the converter.
7 Open the grounding switch and make sure that the converter is in
‘RdyForMCBOn-state’ (the state of the converter can be checked from signal 8.10 Drive Status Word on the CDP-panel).
8 Close the MCB with the On-Line-pushbutton on the front door of the converter, the breaker should close and the drive should receive the MCB Closed-status-signal.
9 Wait for 10 to 20 seconds (the exact time depends on the converter type), the MCB should be opened by the converter and the fault- message ‘Charging’ should be displayed.
10 Reset the fault and close the MCB with On-Line-pushbutton on the front door of the converter.
11 Wait for about 5 seconds and trip the MCB with the E-stop-button on the front-door of the converter, the MCB should be opened by the converter and the fault-message ‘EmergOff’ and ‘TrippLoop’ should come up.
12 Reset the faults and close the MCB with the On-Line-pushbutton on the front door of the converter.
www.PLCworld.cn
www.91HMI.com
www.PLCworld.cn
13 Wait for about 5 seconds and open the MCB with the Off-Line- pushbutton on the front-door of the converter, the breaker should open and the drive should go to RdyForMCBOn-state.
14 Test all used trip-signals connected to the tripping-loop and make sure that the converter shows the correct fault for each signal.
15 Set the converter to Remote control and test the remote control of the MCB.
16 Check the mechanical interlocking of the grounding isolator.
8.3.6. Testing of I/O’s
Check all customer-specific signals. For more information see the customer specific wiring diagram and the Signal & Parameter-table.
8.3.7. Testing of Fieldbus-Communication
Check that the Fieldbus-communication is working properly. For more information see the Signal & Parameter-table and the Fieldbus-module specific Installation and Start-Up guide.
IMPORTANT!
If the Fieldbus is only used for monitoring, parameter 75.04 FBA Comm.Module must be set to DSET1 READ.
If parameter 75.04 FBA Comm.Module is set to DSET1 R/W, the bits 2 and 3 in the OCW (Overriding Control Word) must be set to 1 to prevent the drive to trip to the fault “EmergStop” when the drive is in remote mode.
8.4. Motor
Check that the motor is ready to start (alignment, coupling, lubrication, cooling etc.) and make sure that starting the motor does not cause any danger. It is recommended to disconnect the motor from the load for the first start if there is a risk that the load is damaged in case the motor turns in the wrong direction.
