GENERAL WIRING INSTRUCTIONS
WARNING – THE FAN AND ANY ANCILLARY CONTROL EQUIPMENT MUST BE
ISOLATED FROM THE POWER SUPPLY DURING INSTALLATION AND/OR
MAINTENANCE. THE EQUIPMENT MUST BE EARTHED.
1.
All electrical connections should be made by a properly qualified electrician.
2.
All wiring and connections must be carried out in accordance with current
regulations.
3.
To comply with safety standards, an all pole isolator switch with a contact gap of
at least 3mm must be fitted adjacent to the fan.
4.
Remove the cover from the terminal box to expose the main terminal block and
the thermal protection block (TK). The thermal protection device fitted is an
automatic resetting type which must always be included in the circuit. For ducted
applications a manual reset is required, an ancillary circuit will be required with the
TK switch connected into the circuit. See page 6 for instructions.
5.
Connect the power supply from the local isolator (via any appropriate controls if
fitted) to the terminal box via the supplied cable gland using between 4.0mm and
7.0mm diameter cable. Refer to the wiring diagrams and select the appropriate
connections for the fan, controller or other devices as being installed. If in doubt
please ask.

CAUTION
: In order to avoid a hazard due to inadvertent resetting of the thermal
cut-out, this appliance must not be supplied through an external switching device,
such as a timer, or connected to a circuit that is regularly switched on and off by
the utility.
7.
Ensure that all earth connections have been made.
8.
After making connections inside the terminal box, replace the cover ensuring that
the sealing gasket is in place. Also ensure that all cable gland nuts, grommets etc.
have been used correctly to prevent the ingress of water.
