8.3.3. Wiring the relay output
DANGER
Danger due to the operation of the relay outputs of a UL
device in a wet location.
▶ If a UL device is used in a wet location:
- energize the relay outputs with an alternating voltage of
max. 16Vrms and 22.6Vpeak.
- or energize the relay outputs with a direct voltage of
max.35VDC.
The relay output operates either in normally open mode (NO) or
in normally closed mode (NC), depending on the connection of
the load to the electronic board of the device.
→ Protect the relay with a fuse (3A max.) and, depending
on the application, with a circuit breaker.
Do not apply both a dangerous voltage and a safety extra
low voltage (SELV) to the relay.
→ Wire the relay output to operate in normally open mode (see
Fig.23) or in normally closed mode (see Fig.24).
→ Earth the device (see Fig.23 or Fig.24).
