Proper rotation of pump impeller is critical on three phase motors. See Motor Rotation under Operation section and Figure 12.
WIRING
1.Install, ground, wire and maintain this pump in accordance with your local electrical code and all other codes and ordinances that apply. Consult your local building inspector for local code information.
2.Ground the pump permanently using a wire of size and type specified
by local or United States National Electrical Code. Do not ground to a gas supply line.
3.Connect ground wire first. Connect to ground first, then to green grounding terminal provided on the motor frame, identified as GRD. Ground connection MUST be made to this termi- nal. Do not connect motor to electrical power supply until unit is permanently grounded; otherwise serious or fatal electrical shock hazard may be caused.
4.Connect the other end of the ground wire to a properly grounded service panel or to a control panel ground bar if it is connected to the power supply ground.
IMPORTANT: Check local and/or United States National Electric Codes for proper grounding information.
Make certain that the power supply conforms to the electrical specifications of the motor sup- plied. See Motor Data Charts.
