Preparing for installation
Before installing the pump at a work site, you will need to have the
following tools and instruments ready:
Insulation resistance tester (megohmmeter)
AC voltmeter
AC ammeter (clamp-on type)
Bolt and nut tighteners
Power supply connection tools (screwdriver or box wrench)
Note: Please also read the instructions that come with each of the test
instruments.
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.
Reference insulation resistance: 20MW or greater
Note: The reference insulation resistance (20MW or greater) is the
value when the pump is new or has been repaired. For the reference
value after installation, see “Maintenance and Inspection.”
Precautions During Installation
Do not under any circumstances install or move the pump by
suspending it from the cable assembly. The cable may be damaged,
causing electrical leakage, shock, or fire.
When installing the pump, pay close attention to its center of gravity
and weight. If it is not lowered into place correctly, it may fall and be
damaged or cause injury.
When transporting the pump by hand, be sure to employ manpower
commensurate with the weight of the pump. To avoid back injury when
lifting the pump, bend the knees to pick it up rather than bending your
back only.
2.3.1 Avoid dropping the pump or other strong impact. Lift the pump by
holding it firmly with the hands or by attaching a rope or chain to the
handle.
Note: On cable assembly handling, see Electrical Wiring.
2.3.2 Install the pump in a location with sufficient water level, where water
collects readily.
WARNING
CAUTION
Operation PSG2 500
wc_tx000820gb.fm 10
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.
2.3.3 The hose should be run as straight as possible, since excessive
bending will hinder the water flow, preventing sufficient lift, and can
even cause the hose to become clogged with earth. If the hose is
crimped near the pump, air can become trapped in the pump and
cause idle running.
If large quantities of earth are sucked up, damage resulting from
friction in the pump can lead to electrical leakage and shock.
2.3.4 Use the pump in the upright position. If there is a risk of the pump
drawing in debris or sediment, operate the pump inside a basket or by
enclosing it in a net.
2.3.5 If used in a permanent installation, where the pump is not readily
accessible after installation, please contact Wacker for a duplicate
nameplate to be installed at the wellhead or on the control box so that
it will be readily visible.
2.4 Electrical Wiring
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.
ALWAYS make sure the pump is equipped with the specified overload
protectors and fuses or breakers, so as to prevent electrical shock from
a current leak or pump malfunction.
Operate within the capacity of the power supply and wiring.
Grounding
DO NOT use the pump without first grounding it properly. Failure to
ground it can lead to electrical shock from a current leak or pump
malfunction.

DO NOT attach the grounding wire to a gas pipe, water pipe, lightning
arrester or telephone grounding wire. Improper grounding can result in
electrical shock.
Connecting the power supply
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.
Do not use the pump with the cable assembly or plug connected
loosely, which can result in electric shock, shorting, or fire.
Draw power from a dedicated power outlet rated at 15 A or above.
Sharing the outlet with other equipment may cause overheating at the
branch outlet and could result in fire.
NOTICE: Be sure to use a dedicated power supply with a ground
leakage circuit breaker.
Grounded plug
Connect only to receptacle of proper voltage and current rating
matching that of the plug provided with the cable assembly.
Without Plug
Tighten the ends of the cable assembly securely against the terminal
board. If installation of a grounded plug is required, use only a properly
rated and approved CEE plug and secure the ends of the cable
assembly securely to power and ground terminals in accordance with
the plug manufacturer’s instructions.

Cable Assembly
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.
Be careful not to let the cable assembly be cut or become twisted. This
may result in damage to the pump, electrical leakage, electrical shock,
or fire.
If it is necessary to submerge the connection wires of the cable
assembly in water, first seal the wires completely in a molded
protective sleeve, to prevent electrical leakage, electrical shock, or fire.
DO NOT allow the cable assembly wires or power supply plug to
become wet.
Make sure the cable does not become excessively bent or twisted, and
does not rub against a structure in a way that might damage it.
If used in a deep-well installation, the cable assembly should be
secured every twenty feet.
