CAUTION
National safety regulations

Failure to comply with national safety regulations may result in personal injury and property damage.

  1. Observe national provisions and comply with the appropriate safety regulations.

  • Electrical expertise is required for the installation.
  • The installation must be performed by a specialist.
  • Do not open the casing of the device.
  • No DC or AC voltage may be connected to the inputs for connecting the potential-free contacts. This leads to damage or destruction of the input or the device as well as to voltage carry-over to the bus.
  • When connecting the potential-free contacts to the terminals, safe isolation from dangerous voltages must be maintained.

Incorrect installation can deactivate electrical safety features without this being apparent to a lay person.
