SAFETY
All electrical installation must be undertaken by a suitably qualified and competent person and must be carried
out in accordance with all relevant Statutory Requirements. Please check the details on the unit rating plate to
ensure that the correct power supply (Voltage, Frequency and Phase) is available. Do not use the speed
controllers with an incorrect power supply, overheating and failure of the circuit board will occur.
The controller must not be used when the ambient air temperature may exceed 40ºC and where it is liable to be
subjected to water spray.
INSTALLATION
The controller is suitable for surface mounting only. Remove front cover and ensure back box is securely fixed
to wall in a well-ventilated area. Route supply and load cables through `Knock-out` holes provided. 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 and select the appropriate connections for
the controller and / or other devices as being installed. Ensure that all earth connections have been made.
Transformers within these controllers are not short circuit proof and the necessary short circuit and overload
protection must be provided.
