wall in a well-ventilated area. Route supply and load cables through the “knock-out” holes provide
If the controller is mounted on a conductive (metal) surface, that surface must be earthed.
GENERAL WIRING
WARNING:-The control Equipment Must Be isolated from the power supply during installation and/or
maintenance. The Equipment must be earthed.
Connect the power supply from the local isolator (via any appropriate controls if fitted) and the load supply to the back
box via an appropriate cable gland. Refer to the wiring diagram.
Ensure that all earth connections have been made.
After completing and checking the connections to the controller replace the front cover ensuring that it is correctly
seated in place. Ensure that all cable gland/grommet fixings and lid fixings are tightened correctly to prevent water
ingress.
OPERATION
Switch on the mains supply and select either Forward or Reverse via the control rocker switch. Check required
rotation of fan and turn the control knob from minimum to maximum to ensure the fan operates correctly.
The minimum speed is preset and does not normally need adjusting. If adjustment is necessary ensure control knob is
set to minimum speed, and then remove the front cover to access the adjustment potentiometer (Labelled minimum
voltage).
Warning:- When adjusting potentiometer mains voltage is present. It is the responsibility of the user to
ensure compliance with all statutory safety regulations.
Ensure that at the selected minimum speed the fan will start from stationary for both directions of rotation otherwise
overheating and damage to the fan may occur.
