4 Operation
4.1 Before Starting
1. Make sure once again that the product is of the correct voltage and frequency
rating.
NOTICE: Using the product at other than rated voltage and frequency will not only
lower its performance but may damage the product.
Note: Confirm the rated voltage and frequency on the model nameplate.
2. Confirm the wiring, supply voltage, circuit breaker capacity, and motor insulation
resistance.
Reference insulation resistance = 20 MΩ or greater.
Note: The reference insulation resistance (20 MΩ or greater) is the value when the
pump is new or has been repaired. For the reference value after installation see
“Periodic Maintenance Table.”
3. The setting on the circuit breaker or other overload protector should be made in
accord with the rated current of the pump.
Note: See “Operating Specifications” for the rated current of the pump.
4. When powering the pump with a generator, be certain the generator is sized to
supply the required power for the pump and any other equipment powered by
the generator.
Non-Automatic Model (PS2 800, PSW3 1500)
Test Operation
 Do not operate the pump while it is suspended in the air. The recoil may result in
injury or other major accident.
 Do not start the pump when people are standing next to it. A current leak can
result in electrical shock.
Run the pump for a short time (3–10 minutes) and confirm the following:
 Using an ammeter (clamp-on type), measure the operating current at the L1 and
L2 phase wires on the terminal.
COUNTERMEASURE: If the operating current exceeds the rated value, pump
motor overload may be a cause. Make sure the pump has been installed under
proper conditions as described in Installation.
 Using an AC voltmeter (tester), measure voltage at the terminals. Supply volt-
age tolerance: within ±5% of rated voltage.
COUNTERMEASURE: If the supply voltage is outside the tolerance, possible
causes are the power supply capacity or an inadequate extension cable. Look
again at the wiring diagram and make sure the conditions are proper.
In case of very excessive vibration, unusual noise or odor, turn off the power
immediately and consult your nearest dealer or Wacker Neuson representative.
Continuing to operate the pump under abnormal conditions may result in electrical
shock, fire, or current leakage.
