Installation 3.2 PS 2 500 / PS 2 750 / PSA 2 500 Preparing the Machine for First Use When the pump is delivered, first perform the following checks: • Inspection While unpacking, inspect the product for damage during shipment, and make sure all bolts and nuts are tightened properly. • Specification check Check the model number to make sure it is the product that was ordered. Be certain it is the correct voltage and frequency.
PS 2 500 / PS 2 750 / PSA 2 500 Installation Note: See “Operating Water Level” for the water level necessary for operation. The discharge end of the hose should be located higher than the water surface. If the end of the hose is submerged, water may flow back to the pump when the pump is stopped; and if the hose end is lower than the water surface, water may overflow when the pump is turned off. 3.3.
Installation CAUTION PS 2 500 / PS 2 750 / PSA 2 500 Model PSA2 500—Do not lift or hang the pump by the level relay unit (1). It will lead to damage and may cause leakage, electric shock, and fire See Graphic: wc_gr000259 1 wc_gr000259 16 wc_tx001971gb.
PS 2 500 / PS 2 750 / PSA 2 500 3.5 Installation Checks to Make Before Installation • When a grounded plug is used: Use the megohmmeter to measure the insulation resistance between the cable assembly prongs and ground. • When connection leads are used: With the megohmmeter, measure the insulation resistance between each core lead and the ground lead.
Installation 3.6 PS 2 500 / PS 2 750 / PSA 2 500 Electrical Wiring WARNING Performing electrical wiring Electrical wiring should be performed by a qualified person in accord with all applicable regulations. Failure to observe this precaution not only risks breaking the law but is extremely dangerous. Incorrect wiring can lead to current leakage, electrical shock or fire.
PS 2 500 / PS 2 750 / PSA 2 500 3.7 Installation Connecting the Power Supply WARNING CAUTION Before connecting leads to the terminal strip, make certain the power supply is turned off (circuit breaker, etc.), to avoid electrical shock, shorting, or unexpected starting of the pump, leading to injury. Before inserting the power supply plug, make certain the power supply is turned off (circuit breaker, etc.), to avoid electrical shock, shorting, or unexpected starting of the pump, leading to injury.
Installation 3.8 PS 2 500 / PS 2 750 / PSA 2 500 Cable Assembly CAUTION If it is necessary to extend the cable assembly, use a core size equal to or larger than the original. This is necessary not only to avoid a performance drop, but to prevent cable overheating which can result in fire, electrical leakage or electrical shock. If a cable with cut insulation or other damage is submerged in the water, there is a danger of damage to the pump, electrical leakage, electrical shock, or fire.
PS 2 500 / PS 2 750 / PSA 2 500 4 4.1 Operation Operation Before Starting 4.1.1 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. 4.1.2 Confirm the wiring, supply voltage, circuit breaker capacity, and motor insulation resistance.
Operation CAUTION WARNING PS 2 500 / PS 2 750 / PSA 2 500 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.
PS 2 500 / PS 2 750 / PSA 2 500 4.2 Operation Operating Water Level CAUTION Do not operate the pump below the C.W.L. (Continuous running Water Level) indicated below.
