Wiring
The wiring between the transmitter and the station must NEVER be installed in a conduit together with
power, control or power supply cables.
Always disconnect the power supply to do the wiring.
Cables for wiring the relay contact should have an adequate section depending on the unit to be connected.
Certain international standards maintain that the power supply of the alarm should originate from a different
circuit to that used by the refrigeration and ventilation system.
Please ensure that you comply with
current local regulations.
