 GENERAL WIRING

Warning:- The Fan And Ancillary Control Equipment Must Be Isolated From The Power Supply During Installation

And / Or Maintenance. The Equipment Must Be Earthed.

All-pole disconnection must be incorporated into the fixed wiring.

Only fixed wiring in conduit is required. Flexible cord must not be used.

1. Remove the cover from the fan terminal box.

2. Connect the power supply from the local isolator (via appropriate controls) to the terminal box/switch via an

appropriate cable gland.

3. Refer to the wiring diagrams and select the appropriate connections for the fan, depending on the controller or

other devices being installed.

4. Wiring instructions for the control equipment being used should be considered when making connections to

the fan terminals.

5. Controls must include non-self resetting overload protection.

6. In addition to non-self resetting overload protection, 3 phase products must be provided with single phasing

prevention.

7. Where products have TK connections on the fan terminal strip, these are independently connected to a

thermal switch in the windings of the motor and should be used as part of the control system.

8. 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.

Non-self resetting protection must be provided for this range of fans. If the 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.

Fuses in the circuit should be regarded as only protecting the wiring against short circuits or earth faults; they are

not suitable for overload protection. Fuse ratings must be able to carry starting loads, which can be taken as a

maximum of six times the running current for 25 seconds.
