4.2.
Before operation
CAUTION:
Improper voltage and frequency of the power supply will prevent the pump from attaining its
full capabilities, and may also lead to current leakage, electrical shock, or fire
1. Once again, check the pump nameplate to verify that its voltage and frequency are correct.
2. Check the wiring, power supply voltage, the capacity of the ground leakage circuit breaker,
and the insulation resistance of the motor.
NOTICE:
Insulation resistance reference value
≥
30M
Ω
. See chapter
3.3. Preparation for installation
for
the test method.
3. Adjust the setting of the overflow protector (i.e. circuit breaker) to the pump's rated current
NOTICE:
Verify the rated current on the pump's nameplate
