480 VAC NEMA 4x Enclosure Input Wiring
Make the incoming 480 VAC three phase power connections. See Figure 5-7 480VAC NEMA 4x AC Input
Wiring Termination Details to assist with wiring details. Note that input wiring for 480 VAC NEMA 4x models
is routed to a supplied terminal strip block.
At this point power wiring is complete. At this point you should apply power to the MPC VECTOR and
your attached pump to ensure proper power wiring connection. See Section 6 for start-up screen
information. Do not attempt to start the pump until MPC Vector configuration has been completed in
Section 6 .
WAIT A MINIMUM OF 5 MINUTES AFTER DISCONNECTING POWER BEFORE SERVICING THE MPC
VECTOR OR PUMP MOTOR. CAPACITORS RETAIN A CHARGE EVEN AFTER POWER IS REMOVED
FROM THE CONTROLLER.
