3.1 Overview of installation
Warning
Before carrying out installation and maintenance work
always switch off the power supply for the electronic
components.
You can thereby avoid:
– unexpected movements of the connected actuators
– non-defined switching states of the electronic
components.
Caution
Faulty pre-assembled lines may destroy the electronics
and trigger unexpected movements of the motor.
• For cabling the electric components of the system, use
only the cables listed as accessories (see Tab. 3/2). This
is the only way to ensure the system will work properly.
Caution
Earth or ground loops can under circumstances cause EMC
protective measures to become ineffective, resulting in
high compensating currents which will damage the motor
unit (e.g. with faulty power supply).
• Connect only one cable shield (control cable or supply
cable) to functional earth (FE).
The GND connection must not be connected to the hous-
ing, the shield or functional earth (FE)!
