• The voltage drop in long cables must be taken into account. The drive unit’s rated voltage is the
voltage measured at the terminal board in the upper part of the pump.
• The screened cable must be used according to the European CE requirements if a Variable Frequency
Drive (VFD) is used. For more information, contact your ITT representative (VFD-supplier).
Earthing (Grounding)
Electrical Hazard:
• You must earth (ground) all electrical equipment. This applies to the pump equipment, the driver, and
any monitoring equipment. Test the earth (ground) lead to verify that it is connected correctly.
• If the motor cable is jerked loose by mistake, the earth (ground) conductor should be the last
conductor to come loose from its terminal. Make sure that the earth (ground) conductor is longer
than the phase conductors. This applies to both ends of the motor cable.
• Risk of electrical shock or burn. You must connect an additional earth- (ground-) fault protection
device to the earthed (grounded) connectors if persons are likely to come into physical contact with
the pump or pumped liquids.
Connect the motor cable to the pump
CAUTION:
Leakage into the electrical parts can cause damaged equipment or a blown fuse. Keep the end of the motor
cable above the liquid level.
