GENERAL WIRING INSTRUCTIONS
WARNING
- ISOLATE MAINS SUPPLY BEFORE MAKING CONNECTIONS - THIS EQUIPMENT MUST BE
EARTHED
All electrical connections should be made by a properly qualified electrician.
IMPORTANT NOTE:
The electrical circuit must be protected with an all pole isolator having a
minimum of 3mm contact separation with suitable fuses or circuit breaker.
Remove the cover from the fan terminal box. Connect the power supply from the local isolator (via
any appropriate controls, if fitted) to the terminal box via an appropriate cable gland. Refer to the
wiring diagrams and select the appropriate connections for the fan, controller or other devices as
being installed. Ensure that all earth connections have been made.
After completing and checking the connections to the terminal box, replace the terminal box lid
ensuring that the gasket is correctly seated in place. Ensure that all cable gland / grommet fixings
and terminal box lid fixings are tightened correctly to prevent water ingress.
All fans are fitted with thermal protection (TP). If the thermal protection device operates you MUST
check for the cause before allowing the fan to resume operation. Failure to do so may cause damage
to the motor and invalidate the guarantee.
