6.4 Requirements to the connecting cables
h
Always use shielded cables
h
You must consider IEC/EN 60204-1, chapter 13 at selection of connection cables.
h
The protective conductor cross section of the cable must be executed accordant to
IEC/EN 60204-1, section 5.2, tab. 1.
h
The permanent connection of the protective conductor is imperatively regulated for the
operation of the device.
h
Use a copper cable for at least 60°C (drives < 3 x 100 A) incase you consider UL 508 C.
6.5 Protection of the device and of the cable respectively
In order to protect the device or the cables against damage/destruction by the mains, you
must install fuses. Data of the necessary fuses are to be found in
Z

from page 146.
6.6 PE connection and RCD compatibility
Due to the operating principle leakage current can flow via the protective conductor
> 3.5 mA
AC
or > 10 mA
DC
. On this account a permanent protective conductor is pre-
scribed. In addition to the plugged protective connection, the screw terminal, which is
marked with „PE“ must be connected to the PE (see
Z
Connection diagrams

from page
48).
Due to high leakage currents, which arise due to the operating principle of the device, can
result in an early enabling of the RCD or generally can avoid an enable.
WARNING
The following may occur , if you disregard these safety notes:
m
serious personal injury
m
death
This product can cause direct current in the protective conductor.If, in case of a direct or indi-
rect contact a residual-current-operated protective device (RCD) is used, then a RCD of type
B is permitted on the power supply side only. Otherwise other safety precautions must be
made as e. g. environmental separation with a double or strengthened insulation or by the
separation of the power supply with an isolated transformer.
