4. INSTALLATION
4.1 GENERAL PROCEDURES
The majority of 4A and 10A Single Phase
EnviroStart
units will be shipped pre-wired with
five core cable suitable for the current rating of the unit. If this is the case then ignore the
following section as it is not relevant to your installation. (Refer to the wiring diagram at the
end of this Installation and Commissioning Guide for details of the cable connections).
When ready to install the unit, unscrew and remove the lid. Make ready your connection
cables from the supply and to the motor to be controlled and thread them through the glands
found on the side of the unit. Make the ends of the cable off and connect into the terminals,
which are found on the circuit board. Make sure the earth cables are connected between the
box, lid and circuit board terminal block and replace the lid.
If the
EnviroStart
has been pre-wired then the cable supplied may be either numbered or
colour coded.

EnviroStart provides terminals for the incoming mains supply and also a set of auxiliary
connections to provide supply for additional components that cannot be optimized such as
secondary fans in refrigeration systems and condenser pumps in freezers.
The controlled output to the motor is found on a separate connector set clearly marked
“Motor”. Under no circumstances should the supply voltage be applied to this connector
block.
