Connect the Power Supply
WARNINGS
1. MAINS SUPPLY VOLTAGES (220-240 V AC) ARE PRESENT IN THIS EQUIPMENT WHICH MAY CAUSE
DEATH OR SERIOUS INJURY BY ELECTRIC SHOCK. ONLY A QUALIFIED ELECTRICIAN OR INSTALLER
SHOULD CONNECT THE POWER SUPPLY TO THIS UNIT.
2. THIS UNIT MUST BE CORRECTLY EARTHED.
This unit is designed for operation from a single-phase alternating current source (220-240 V AC). A 1.5 m cable
is connected internally to the unit for connection to a switched fused spur.
To connect the power supply:
1.
Ensure the local AC power supply is switched off.
One end of the power cable supplied is already connected to the unit and routed through the Cable Inlet
Plate via a suitable gland to ensure the IP rating of the unit is not affected.
Connect the other end of the cable to the switched fused spur.
Use cable clamps and clips to secure the cable, as appropriate.
Connecting a Boost (Light) Switch
A Switched Live (LS) may be used to boost the airflow when a light is turned on, for instance in a bathroom or
kitchen.
Power supplied to the unit via a 3 pole isolating switch must be supplied via the same circuit as the LS
connection.
