9. ELECTRICAL CONNECTIONS
Connection of the pump must comply with local electrical codes and be carried out by qualied personnel.
When connecting the pump, the following must be considered:
• Liquid tight power connection required to maintain the Totally Enclosed, IP44 enclosure rating.
Use the supplied thread adapter for exible or armored cable installations.
• Local or national electrical code requirements supersede Taco’s specication.
• Install an electrical disconnect to comply with national electrical code.
• Connection of the power supply electrical cable must be done in a manner that ensures it does not
contact the motor housing and volute of the device, due to potential high temperatures of both.
The pump has built-in over current fuse protection, temperature protection, and basic overvoltage protection. It does
not require additional overload protection devices unless required by local electrical codes. Power supply cabling should
be capable of carrying rated power and be properly fused. Grounding connection is essential for safety and should be
connected rst. Grounding is only meant for pump safety. System piping should be grounded separately.
