3.5 Electrical Connections
Wiring must be done by a qualified electrician. Otherwise, electric shock
or fire may occur.
Turn off the incoming main electrical power before wiring the pump. Failure
to do so can cause injury from electric shock.
Check eIectric power and voltage before doing the wiring.
The three-phase motor can be operated off two different mains voltages:
either 200/380V 50 Hz or 208/460 V 60 Hz.
The single-phase motor can be operated off two different mains voltages:
either 100/200V 50 Hz or 115/208-230V 60 Hz.
Check mains voltage and wiring.
3.5.1 Single-phase Motors
Be sure to install a reliable main disconnect switch (or breaker) for emer-
gency stop. In addition, shut off the SC 5 D by turning off the switch on
the motor. Failure to do so can cause damage or fire.
The single-phase motor has an internal thermal protector. The motor
restarts without warning after the protector trips back.
CE Requirements
Min. circuit current capacity of conductor is 10 A. Max. branch circuit breaker
is 15 A (industrial rated).
Protect the motor by installing the recommended breaker (refer to Table 1).
Failure to do so can cause electrical shock or fire.
