6.2.3 Special Circuitry
a) Circuitry for line fault detection if the contacts at the input are de-energised
Schematic
 Create the circuitry for line fault detection in the immediate vicinity of the contact.
b) Circuitry with inductive loads at the output
Schematic
 Connect inductive loads using a freewheeling diode.
Do NOT connect using a varistor.

Parameterization and Commissioning

DANGER! Explosion hazard from operating the DIP switches in Zone 2 while they are
live!
Non-compliance may result in serious or even fatal injury.
 Adjust the DIP switches exclusively in a de-energised state.
Before commissioning, carry out the following checks:
• Mounting and installation of the device according to regulations.
• Correct, secure connection of the cables.
• No damage to the device or the cables.
• The screws are securely fastened to the terminals.
Correct tightening torque: 0.5 to 0.6 Nm.
 Do not commission the device until it has been successfully tested.
