1.2 Electromagnetic Compatibility
Introduction
In this section you will find details of the noise immunity of S7-300 modules and details of radio interference suppression.
The S7-300 modules satisfy, among other things, the requirements of the law applicable to EMC on the European domestic market.
Definition of ”EMC”
Electromagnetic compatibility (EMC) is the ability of an electrical installation to function satisfactorily in its electromagnetic environment without interfering with that environment.
Pulse-Shaped Interference
The following table shows the electromagnetic compatibility of modules compared to pulse-shaped disturbance variables. A requirement for this is that the S7-300 system complies with the specifications and directives on electric design.

Transporting Backup Batteries
Wherever possible, transport backup batteries in their original packing. Special approval does not have to be obtained for transporting backup batteries for S7-300 systems. The lithium content of the backup battery is approximately 0.25 g.
Storing Backup Batteries
Backup batteries must be stored in a cool and dry place. The maximum shelf life is 5 years.
!
WarningImproper handling of backup batteries can result in injury and damage to property.If backup batteries are not treated properly, they can explode and cause severe burning.
Observe the following rules when handling backup batteries used in the S7-300 programmable logic controller:
never charge them
never heat them
never throw them in the fire
never damage them mechanically (drill, squeeze, etc.)

1.4 Mechanical and Climatic Environmental Conditions for Operating S7-300s
Operating Conditions
S7-300 systems are intended for stationary use in locations protected against the weather. The operating conditions surpass the requirements of IEC 61131, Part 2.
The S7-300 satisfies the operating conditions of Classes 3M3 and 3C3 to DIN EN 60721, Part 2.
Use with additional measures
The S7-300, for example, must not be used without taking additional measures:
in locations exposed to a high degree of ionizing radiation
in hostile environments caused, for instance, by – dust accumulation
– corrosive vapors or gases – strong electric or magnetic fields
in installations requiring special monitoring, for example – elevators
– electrical installations in particularly hazardous areas
An additional measure might be, for instance, installation of the S7-300 in a cabinet or in a housing.
Ambient Mechanical Conditions
The ambient mechanical conditions for S7-300 modules are listed in the following table in the form of sinusoidal oscillations.
Table 1-5 Mechanical Conditions Frequency Range

Reducing Vibrations
If your S7-300 modules are exposed to severe shock and/or vibrations, you must take the appropriate measures to reduce the acceleration and/or amplitude, respectively.
We recommend that you install the S7-300 on vibration-damping materials (for example, rubber-metal antivibration mountings).
