CABLE LEAD WIRE CONNECTION TO STARTER
DIRECT ONLINE STARTER
CAUTION
*
Hazardous voltage-Will cause death, serious injury,
electrocution.
*
All electrical work must be performed by an authorized
electrician in compliance with local electrical
equipment standards and internal wiring codes
CHECKING DIRECTION OF ROTATION OF OWS
l
In case the OWS is used to lift water from a borewell located at the bottom of a
well first prime the pump.
l
Connect the OWS to Control Panel, power up the OWS, and observe the
discharge from the pump.
l
Next interchange any two-phase wires, power up the OWS, and observe the
discharge from the pump.
l
In case the discharge is more after interchanging any two-phase wires, then the
impeller is rotating in the correct direction within the volute casing.
l
If the discharge after interchanging any two-phase wires is lower, then the
previous phase wire connection was correct. Now revert to the old phase wire
connection.
ELECTRICAL INSTALLATION
l
Check power supply voltage and frequency and compare with product
requirements specified on the name plate.

CAUTION
*
All electrical work must be performed by an authorized
electrician in compliance with local electrical
equipment standards and internal wiring codes
*
Improper wiring can lead to current leakage, electrical
shock, or fire.
l
Observe relevant EB regulations while providing power supply to the motor.
l
As far as possible, do not use multiple joints in the electrical cabling while
connecting the Control Panel to the OWS.
l
Ground the OWS using the two earth screws provided on the leg of the motor
body.
l
Ensure electrical joints, if any, are properly and adequately insulated.
l
Connect the cable properly to starter terminals to avoid loose connections.
l
Factor in low-voltage operation while selecting cable size.
ELECTRICAL WIRING WORK
CAUTION
*
Be sure to install the ground wire securely. Failure to
observe this precaution could damage the pump and
cause current leakage, which may lead to electrical
shock.
*
Do not connect the ground wire to a gas pipe, water
pipe, lightning rod, or telephone ground wire. Improper
grounding could cause electrical shock.
EARTHING
CONNECTING THE POWER SUPPLY
CAUTION
*
Observe relevant Electricity Board regulations while
powering up the Pumpset.
*
Before inserting the power plug or connecting the wires
to terminal board, make sure that the power supply is
properly disconnected. Failure to do so may lead to
electrical shock, short circuit, or injury caused by
unintended starting of the pump.
*
Do not use damaged cables, power plugs, or loose
power outlets. Failure to observe this precaution could
lead to electrical shock, short circuit, or fire.
