3.2 GENERAL CONSIDERATIONS

1. The installer should be a competent person for installation of electrical goods.
2. The power should be disconnected before installation and only put back on once installation is
complete.
3. The only motors for which the Single Phase EnviroStart is suitable are 110v AND 220V AC
single-phase induction motors. (Also known as "Cage" or "Squirrel Cage" motors). EnviroStart
cannot be used on DC motors, Switched Reluctance motors or any form of Three Phase
motor.
4. Check that the current rating of the unit is the same or higher than the full load current (FLA) of
the motor, which should be on the nameplate of the motor. If in doubt contact the motor
manufacturer or supplier.
5. Use the correct size of cable for the current rating of the unit, (See Section 3.11)
6. The EnviroStart must be installed as the last piece of equipment before the motor.
