7. Motor Connections
To mains:
7.1. Connection of the electric motor to the mains supply should be made by a qualified person. The current
rating of the motor will be identified on the motor plate, and correct sizing of the cables to electrical
regulations is essential.
Motor terminal connection:
7.2. Circuit diagrams for the correct wiring of the motor terminal box are included as Appendix 3 of this
document if the motor is fitted with our ‘own brand’ motor.
Alternatively if the motor is supplied separately or if fitted with a motor from a different manufacturer,
then this should have appropriate documentation provided with it.
8. Starting Up
8.1. Prior to starting up
8.1.1. Ensure ventilator is fitted (if supplied) see lubrication section 6.2
8.1.2. Check oil level, top up if necessary.
