3.1. Mains connection and line protection
Danger! Never carry out work on live parts!
Danger to life!
• When connecting the 3-phase network, it is essential to observe the terminal identification!
•Protection:
• The rated control supply voltage and control voltage inputs must be operated with power supply
modules in acc. with DIN 19240 (max. 5% residual ripple)!
For devices with 230 V AC control, make sure that the same phase is used
for the rated control supply voltage as well as the control inputs!
• In order to avoid inductive or capacitive decoupling of disturbing pulses where long control wires are
used, we recommend the use of shielded conductors.
If you want to clamp two conductors under one terminal point, you must use a
conductor with the same conductor cross-section.
