Overvoltage protection module
Instructions
WARNING
!
HAZARDOUS VOLTAGE.
Can cause electrical shock
and burns.
Disconnect power before proceeding
with any work on this equipment.
Reliable functioning of the equipment is only ensured with certified components.
Application
Installation/wiring
Putting into service
Overvoltage protection modules protect devices or equipment parts in AS-Interface networks from
overvoltages. Depending on the coupling module used, the yellow AS-Interface line, the black
AS-Interface power line and / or the standard round wires are protected. Within the lightning
protection zone concept, the point of installation constitutes the transition from lightning
protection zone 1 to lightning protection zone 2/3 (DIN VDE or ENV). Direct lightning strikes must
be countered by additional protection measures applied at the transition between protection zones
0 and 1. The impedance load of the overvoltage protection module corresponds to that of a slave.

The steps for putting the user module into service are as follows:
Step Procedure
1 Fit the actuator-sensor interface (AS-Interface) conductor rail(s) in the guide(s) on
the coupling module.
2 Screw the overvoltage protection module tightly onto the coupling module.
The LEDs light up when AS-Interface / AUX POWER is available.
3 Connect the earthing conductor with low resistance to the common earth of the
AS-Interface device to be protected.
