4.3.2 Circuit Breaker
It is necessary to connect a suitable circuit breaker between 3 phase AC power
supply and B603 series intelligent constant water supply controller. The capacity of
breaker is 1.5~2 times to the rated current of controller.
4.3.3 AC Reactor (Optional)
In order to prevent the rectifier damage resulted from the large current, AC
reactor should be installed at the input side. It can also prevent rectifier from sudden
variation of power voltage or harmonic generated by phase-control load.
4.3.4 Input EMC Filter (Optional)
EMC filter can minimize the interference of the surrounding device which may be
disturbed by the cables when the controller is working.
4.3.5 Output EMC Filter (Optional)
EMC filter should be installed to minimize the leak current caused by the cable
and minimize the radio noise caused by the cables between the controller and motor.
4.3.6 Output Reactor
When the distance between the B6031I controller and motor is more than 50m,
the controller may be tripped by over-current protection frequently because of the
large leak current resulted from the parasitic capacitance with ground. So as to avoid
the damage of motor insulation, the output reactor should be installed.
