5.3 Versions and mechanical mounting

Version ELMON board 31-30
Printed circuit Board without housing
The switching unit is to be professionally mounted at a suitable location.
Do not install the switching unit in the immediate vicinity of strong sources of heat.
The switching unit may be mounted in any orientation. To prevent moisture penetration, it should, however,
be installed so that the cable conduits point downward.

6. Commissioning

6.1 Prerequisites

• When supplying with 12-24 V AC/DC, the voltage must comply with the requirements for safety low
voltage (SELV).
• Cables installed outdoors or outside of the switching cabinet must be protected appropriately.
• The protection class specified for this device is only ensured if the supply lines have been properly clamped
to the screw connections and the housing cover is appropriately screwed down.

6.2 Electrical connection

• Connect supply voltage 12-24 V AC/DC to terminals 12 24 V AC/DC or 230 V AC to terminals PE L1 N .
• Connect the sensor to terminals X1 X2 .
• Connect the control circuit that is to be monitored to terminals 13 14 .
• Connect the test signal supplied by the primary control to the Test Signal terminals and select the
waveform via DIP slide switch S1.
Upon successful commissioning, safety output 13 14 is activated (relay contact "closed"). Actuation of the
sensor causes relay contact 13 14 to open .
