Requirements for the connection cables
h
Take into account IEC/EN 60204-1, chapter 13 when selecting the cable.
h
The protective ground cross section of the cable must be compliant with IEC/
EN 60204-1, section 5.2, Tab. 1.
h
A fixed connection for the protective ground conductor is mandatorily specified for op-
eration of the device.
h
Use copper cable approved for a minimum of 60 °C (drives < 3 x 100 A) or 75 °C
(drives
3 x 100 A), if comply with UL 508C.
For further details (e.g. maximum allowable length), refer to

PE connection and RCD compatibility
Depending on the functional principle, leakage current >3.5 mA
AC
or >10 mA
DC
can flow
through the protective ground conductor. Consequently, a stationary ground conductor
connection in accordance with EN 61800-5-1 is required.
DANGER!
Risk of fatal injury from electrical current!
This product can cause direct and/or alternating current in the protective ground con-
ductor.
The leakage current, due to the functional principle of the device, can lead to prema-
ture triggering of the fault current protective device or generally prevent triggering of
it.
Therefore:
m
Wherever a differential current device (RCD) is used for protection in case of direct
or indirect contact, only an RCD of the type B is permitted on the power supply side
of the device.
m
Otherwise a different protective measure must be utilized, such as separation from
the surrounding by means of double or enhanced isolation, or separation from the
power supply system by means of an isolating transformer, for example.
