6.1.2 Electromagnetic compatibility
The device has been developed in accordance with applicable EMC stan-
dards. The following points must be noted in order to maintain the EMC
standards.
6.1.2.1 Wiring requirement of installation site
Note the following when selecting the installation site:
▪ The system's overvoltage protection must be effective.
▪ The system's ground connection must comply with all technical regula-
tions.
▪ Separate system parts must be joined by a potential equalization.
▪ The device and its wiring must be at least 10 m away from circuit-break-
ers, load disconnectors and busbars.
6.1.2.2 Wiring requirement of operating site
Note the following when wiring the operating site:
▪ Do not route lines which cause interference (e.g. supply lines) and lines
susceptible to interference (e.g. signal lines) in the same cable duct.
▪ Short-circuit and ground reserve lines.
▪ Never connect the device with a multi-wire collective pipe.
6.1.2.3 Wiring requirement in control cabinet
Note the following when wiring in the control cabinet:
▪ The control cabinet where the device will be installed must be prepared in
accordance with EMC requirements:
– Functional division of control cabinet (physical separation)
– Constant potential equalization (all metal parts are joined)
– Line routing in accordance with EMC requirements (separation of lines
which cause interference and those susceptible to interference)
– Optimum shielding (metal housing)
– Overvoltage protection (lightning protection)
– Collective grounding (main grounding rail)
– Cable bushings in accordance with EMC requirements
– Any contactor coils present must be interconnected
