14. ELECTRICAL CONNECTIONS
14.1. GENERALITIES
Ensure that the available electrical power supply and the network frequency are matched to the required
operating current, taking account of the appliance’s specic location and the current required to supply any
other appliances connected to the same circuit.
1. Ensure that the unit is supplied with the specied voltage. Two stufng boxes and one grommet hole
are provided on the side of the appliance. They are used respectively for the power and the control
wiring. The power supply line must be properly dimensioned with a motor supply type fuse or a
mains circuit breaker to protect the circuit against voltage surges. (Refer to the Maker’s Plate for the
voltages to be taken into consideration).
2. On three phase 400V / 3ph / 50Hz units, a neutral line is necessary for supplying the fan circuit with
230V /1ph / 50Hz.
3. Always shut down the power supply to the unit before connecting the thermostat wiring.
VERY IMPORTANT:
3N~400V-50HZ
The outdoor unit is equipped as standard with a phase sequence and cut-out controller located in the
electrical box.
THIS PRODUCT IS EQUIPPED WITH A PHASE SEQUENCE CONTROLLER. THE LED’s INDICATE THE FOLLOWING
CONDITIONS:
Green LED = 1
Yellow LED =1
Low voltage supply
The compressor rotation
direction is correct
Green LED = 1
Yellow LED =0
Phase inversion or phase
absent (L1)
The compressor and the
fans do not start.
Green LED = 0
Yellow LED =0
Phase absent (L2 or L3)
the compressor and the
fans do not start.
