3. Connection notes
3.1. Mains connection and line protection
CAUTION: Never work when voltage is present!
Life-threatening danger!
• When connecting the 3-phase network, it is essential to observe the terminal identification!
•Protection:
• The control supply voltage and control voltage inputs must be operated with power supply modules in
acc. with DIN 19240 (max. 5% residual ripple)!
In devices with 230 V AC activation, always use the same phase for the control supply
voltage and the control inputs!
• In order to avoid the inductive or capacitive decoupling of disturbing pulses with long control wires, 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.
