Connecting the Power Supply and Light Switch

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 SUITABLY QUALIFIED PERSON SHOULD
CONNECT THE POWER SUPPLY TO THIS UNIT.
2. THIS UNIT MUST BE CORRECTLY EARTHED.
3. ALL EXTERNAL WIRING MUST BE FIXED WIRING
This unit is designed for operation from a single-phase alternating current source (220-240 VAC).
A 1.5m cable is connected internally to the unit for connection to an isolator switch.
If the supply cord is damaged, it must be replaced by a special cord or assembly available
from the manufacturer or its service agent.
To connect the power supply:
Ensure the local AC power supply is switched off.
One end of the power cable supplied is already connected to the unit in the manner shown above.
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. If the LS core of the
mains cable is not used it should be terminated
in an appropriate manner.
The LS connection should only be used if
the switch live is on the same circuit as the
unit.
Connecting a Boost (Light) Switch
from a different circuit
If the supply used for the Switched Live is on a
different circuit to the power connections, the
connections LS2 and NS2 should used, via a
separate isolator.
