230VAC AC monophasic cable:
An electrical separation device must be settled upstream the control box. It must be easily reachable and found and
should be locked in open position. The device can be a disconnecting switch for 6 A current minimum or any other
system that can be connected in an optimal security scenario and in compliance with local regulation.
Note 1: Installation responsible must select the device according to external constraints (humidity).
Note 2: Power supply of the box must be protected according to the earth link scheme (grounding) in compliance
with local regulation.
Note3: For TT operating conditions, the circuit must be protected upstream by a bipolar differential circuit breaker
with a sensitivity of 30 mA, 6 A intensity and a type C trigger curve.
Use a cable H07 VV-F with a cross section of at least 1.5 mm² with 2 wires + ground.
Guide the cable through the provided cable gland.
Three positions key switch
Use a three-wire cable 1.5 mm2, type H07 VV-F for connecting to the board.
Pass the cable through a cable gland.
Connect the key switch to the KEY SWITCH terminal block on the board.
Respect marked references « F C » (F closing) and « O » (Opening) shown on the board and on the switch.
