5.7.1 Auxiliary Lamp Connection - NILD2
The green LED board (NILD2-GAA) has a galvanically isolated relay contact that can be used to connect to
an auxiliary lamp. It has a maximum switching capacity of 0.4A at 60V peak.

IMPORTANT: In order to retain the galvanic isolation, it is not allowed to connect the
GND(-) of the auxiliary power supply to the GND (-) of the NIRC3.
Disabling the LEDs
If the relay contact only is required, without the green LED on the NILD2-GAA board, then the conductor
track should be cut through at the break point to disable the LEDs, as shown in the following illustration:
