No internal line protection for supply lines to external consumers

Risk of fire and injury due to short-circuits

  1. Adapt the line diameters as per local regulations to the rated value of the installed fuse.


Install external supply line fusing in series with relay contacts and controlled device.
Fuse type and value should be lowest required by control relay datasheet or controlled device datasheet.

Failure to install fuse may result in damage to relay or device.

See Relay output (outputs DO1...DO4) in the Outputs section for details.

Relay outputs connected to mains voltage

Injuries caused by electric shock when touching the device

  1. Install the device in a lockable cabinet or use terminal covers.
  1. Install the device in locations where no children are present.
  1. Conductors with a cross-section of 0.5 mm2 (AWG24) or greater must comply with requirements as per IEC 60332-1-2 and IEC 60332-1-3 or IEC TS 60695-11-21.
