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.
Determine the correct overload setting required to protect the
motor (see motor starter manufacturer’s 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 motor’s
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 motor .
