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 specic location and the current required to supply any
other appliances connected to the same circuit.
1. Ensure that the unit is supplied with the specied voltage. Two stufng 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. The electrical power supply three-phase 400V/3ph/50Hz must comprise a neutral to feed the control
circuit.
3. Always shut down the power supply to the unit before connecting the thermostat wiring.
