Checking direction of rotation of Openwell Submersible
Danger
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.
Connect the Openwell Submersibles to the starter, power up the Openwell Submersibles and
observe the discharge from the pump
Next interchange any two phase wires, power up the Openwell Submersibles and observe the
discharge from the pump
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
If the discharge after interchanging any two phase wires is lower, then the previous phase wire
connection was correct. Now revert back to the old phase wire connection
Electrical Installation
Check the power supply voltage and frequency and compare with the product requirements
specified on the name plate
Observe relevant EB regulations while giving power supply to the motor
As far as possible, do not use multiple joints in the electrical cabling while connecting the starter
to the Openwell Submersibles
Ground the Openwell Submersibles using the two earth screws provided on the leg of the
motor body
Ensure electrical joints, if any, are properly and adequately insulated
Connect the cable properly to the starter terminals to avoid loose connections
Factor in low voltage operation while selecting cable size
