3.3 Connecting the cable
Please note
Connection to the main power supply and the fitting of
mains switches, transformers, fuses and mains filters may
only be carried out by a qualified electronics engineer.
Caution
S
Do not connect any cables to the electronics and do not
disconnect any cables before the power supply to the
system is switched off. The electronics of the power
controller and the motor may otherwise be damaged.
S
Check all cables once again before installation, as incor-
rect connection assignments can cause serious func-
tional impairment.
S
Make sure that the SEC-ST is connected to the protective
earth (PE) of the power supply unit.
S
Make sure that the screening cables of the motor are
connected to the earth connection of the SEC-ST before
you commission the motor.
Caution
S
Place the motor cables and the signal cables at a
distance from each other where possible, e.g. in cable
channels with intermediate walls. Use only screened
cables for the connection to the motor and cables
twisted in pairs for signal lines.
In this way you can avoid electromagnetic interference which
might impair reliable operation of the system.
