Wiring the relay output

The relay output operates either in normally open mode (NO) or in
normally closed mode (NC), depending on the connection to the
8041 transmitter's electronic board.
→
Install a safety device for the relay comprising a fuse
(3 A max.) and, depending on the application, a circuit
breaker.
Do not apply a dangerous voltage and a safety extra low
voltage (SELV) to the relay at the same time.
→
Connect the relay output in normally open mode (see
normally closed mode (see Fig. 23 ).
