5.3.1 Pump Motor Wiring
Using a VFD rated cable route the 3 phase motor connections between the MPC Vector AC drive
connections marked U, V, and W as shown in
Figure 5-4 MPC VECTOR Pump Motor Wiring
Termination
below. Next terminate the VFD cable at the pump motor location, being careful to wire the
proper motor voltage connections (generally L1, L2, L3, refer to your motor voltage wiring diagram for
dual voltage rated motors).
The motor wires are secured to the terminal strip at the bottom end of the AC drive. Remove
approximately 0.20 – 0.25” of insulation from the end of each conductor. Loosen the terminal strip screw,
and insert the stripped wire end fully into the terminal. Tighten the screw to secure the conductor
(Torque
Requirement 2.0 lb-in/0.2 Nm)
making certain that the terminal grips the wire, not the insulation.
Ensure that all wiring meets applicable local and national codes and requirements.
Ensure that the motor voltage wiring connections (230/480 VAC) match your MPC Vector voltage rating
by referring to the motor wiring diagram on motor conduit cover. Use the nameplate voltage rating of the
MPC Vector.

5.3.2 AC Line Input Wiring
Verify the correct supply voltage (230VAC single/three phase or 480VAC three phase) with the
nameplate affixed to your MPC VECTOR. Ensure that your AC line input voltage matches the
MPC VECTOR configuration.
The 1 hp, 2 hp, and 3 hp rated MPC VECTOR use single phase or three phase 208-230VAC input.
The 5 hp 230 VAC MPC VECTOR must be powered by three phase input only.
All 480VAC MPC VECTOR use 3 phase power only.
