Motor Control

It is your responsibility to contact a qualified

electrician and assure that the electrical installation is

adequate and in conformance with all national and local

codes and ordinances. The metal capacitor shell must

be grounded.

Determine the correct overload setting required to

protect the motor (see motor starter manufacturerʼs

recommendations). Select fuses, motor protective

switches or thermal protective switches to provide

protection. Fuses act as short circuit protection for the

motor, not as protection against overload. Incoming line

fuses must be able to withstand the motorʼs starting

current. Motor starters with thermal magnetic overload

or circuit breakers protect motor from overload or

reduced voltage conditions.

The wiring diagram supplied with the product provides

required electrical information. Check that power

source is correct to properly operate the dual-voltage

motors.
