POINTS
*1: Overcurrent protection
The overcurrent protection device shuts off the 5VDC and/or 24VDC circuit(s) and stops the system if the current exceeding the specified value flows in the circuit(s).
As this results in voltage drop, the power supply module LED turns OFF or is dimly lit.
After that, eliminate the causes of overcurrent, e.g., insufficient current capacity and short circuit, and then start the system.
When the current has reached the normal value, the initial start up of the system will be performed.
*2: Overvoltage protection
The overvoltage protection shuts off the 5VDC circuit and stops the system if the overvoltage of 5.5 to 6.5V is applied to the circuit.
This results in the power supply module LED turning OFF.
When restarting the system, power OFF and ON the input power supply, and the initial start up of the system will be performed.
If the system is not booted and the LED remains off, this means that the power supply module has to be replaced.
*3: Allowable momentary power failure period
The PLC CPU allowable momentary power failure period varies with the power supply module used.
In case of the A1S63P power supply module, the allowable momentary power failure period is defined as the time from when the primary side of the stabilized power supply for supplying 24VDC to the A1S63P is turned OFF until when the voltage (secondary side) has dropped from 24VDC to the specified value (15.6VDC) or less.
*4: Inrush current
If the power supply module is re-powered ON right after powered OFF (within 5seconds), the inrush current exceeding the specified value (2ms or less) may be generated. Therefore, make sure to re-power ON the module 5seconds after power off.
When selecting a fuse or breaker for external circuit, consider the
above point as well as meltdown and detection characteristics.

The number of the solderless terminals to be connected for one terminal block are limited to 2.
Terminal block Solderless terminals
with insulation sleeves
(2) When the LG and FG terminals are connected, they must be grounded.
If they are not grounded, the operations will be easily influenced by
noise. Be aware not to touch the LG terminal since it has potential of half the input voltage.
4.4 Precaution when Connecting the Uninterruptive Power Supply (UPS) Be sure of the following terms when connecting the PLC system to the
uninterruptive power supply (abbreviated as UPS hereafter):
As for UPS, use the online power system or online interactive system with a voltage distortion rate of 5% or less.
For the UPS of the commercial online power system, use Mitsubishi Electric's F Series UPS (serial number P or later) (Ex.: FW-F10-0.3K/0.5K).
Do not use any UPS of the commercial online power system other than the F
series mentioned above.
