
Wires should be routed within the enclosure in a manner that maintains separation between high
voltage (power) and low voltage (control) conductors. High voltage conductors should be routed to
the side opposite the control circuitry.

Incoming power wiring should adhere to all applicable local and national electrical codes and
regulations. A circuit breaker or fuse(s) must be provided as noted below.

Upon initial application of AC power, a current inrush will occur to charge the DC bus capacitors.
This is normal operation, and breakers and other circuit protection devices should be sized
accordingly.

Motor Rated circuit breakers are recommended for use (allows input surge).

Wiring Torque Requirement 2.0 lb-in/0.2 Nm.

Wire and Ground in accordance with NEC or CEC, and all applicable codes.

Motor wire must run in separate conduit away from control wires and AC line input.

Do not install contactors bewteen the MPC Vector and the motor.

Use only UL and CSA approved wire.

Use 300V rated wire for 208/240 VAC systems and 600V for 400/480VAC systems.

Wire gauge must be based on a minumum of 125% of the rated input/output current of the drive,
and a minimum 75 Degrees C insulation rating. Copper wire only.
5.3.2.1 AC Input Wire and Circuit Breaker Sizing
General Input Wiring Guidance
The MPC VECTOR requires one connection to an external AC power source. The controller uses this AC
connection to power its own internal supply and the AC pump motor. You must take all of these loads into
consideration when sizing the branch circuit. A circuit breaker or disconnect switch with fuses must be wired in
series with terminals L1 and L2/N (single phase) and L1, L2, and L3 (three phase) in accordance with all
applicable local and national electrical codes and regulations. The circuit breaker or disconnect switch shall be
located in close proximity to the MPC VECTOR controller installation, and must be marked or labeled to identify
it as the power disconnect for the MPC VECTOR.
Conduit Entrance
The MPC VECTOR controller is provided with a 7/8” thru hole for incoming AC power wiring and a 7/8” thru
hole for motor wiring at the bottom of the enclosure. Utilize the appropriate conduit fittings to route and seal the
supply wires into the MPC VECTOR enclosure.
Depending on the model you are installing see the appropriate sections below for 230 or 480 VAC to
determine proper AC installation guidelines. See nameplate for HP rating, refer to
