Wiring
Always disconnect the power supply to do the wiring.
The power circuit should be equipped with a switch for its disconnection of at least 2 A, 230 V, situated
near the appliance. The power supply cable should be H05VV-F or H05V-K type. The gauge will depend
on local regulations, but should in no case be less than 1 mm².
Cables for wiring the relay contact should have an adequate section depending on the unit to be connected.
AKO recommends the use of shielded cable for the wiring of the detectors.
Ensure the batteries are connected before switching on the equipment.
