Electrical Connections continued
1. The wires routed from the
terminal block U, V, W, and
ground screw, should now be
connected to the motor leads
using the motor nameplate and
Diagram 6 for reference. Always
refer to motor wiring nameplate.
2. Pressure Transducer
Installation and Wiring
It is recommended that the
transducer be mounted in the
discharge piping. The location should be in a non-turbulent, straight piece of pipe. See layout
