6. Commissioning
6.1 Preconditions
• The voltage supply must correspond with the requirements for safety low voltage (SELV).
• Cables outside the cabinet must be protected accordingly.
6.2 Electrical Connection
• Connect the sensor (edge, mat or bumper) to the clamps

.
• Connect the 24V AC/DC voltage supply to the clamps

.
• Connect the monitored control circuit to clamps

Output Relay
for an „Opener contact“ or to the clamps
COM NC Output Relay
for a „Closer contact“.
• The limit values for supply voltage and switching capability of
the relay indicated in the „Technical Data“ are to be consid-
ered.
After the successful initial operation the safety outputs are activated
(relay contact
COM NO
„closed“ resp. contact
COM NC
„opened“).
Operating the Sensor causes the relay output contact to change
the condition.
6.3 Mechanical Mounting
The mechanical mounting of the relay is to fix
professionally to a suitable mounting place. The
enclosure of the ELMON vario 01-27 permits to
mount the relay in two different ways.
Fig. 1 shows the mounting at a 35 mm DIN rail,
which preferably is in the cabinet.
Fig. 2 shows the direct mounting via two screws on
a suitable underground.
