• For the connection, a double-insulated mains cable
(sheathed cable) with a cross-section of at least 1.5
mm² must be used.
• Cable connection (2) may not be routed in a loop within
the relay trough (1).
• It is recommended that you always tie 2 adjacent cores
to one another using a cable tie (3).
• The insulation of the cable must be fed at least 5 mm
(4) into the relay tray up to the elevated part.

1 Alarm/status light
(example of installation)
2 250 V AC/DC, 3 A
The busy light (alarm/status light) is permanently on until
the relay opens or the circuit is interrupted. This circuit can
therefore be used to monitor the functionality of the alarm
circuit, as a cable break, for instance, is indicated by the
busy light going off.
