Control Input/Output Signal Wiring

5.3.3.1 Determination of Input and Outputs
Based upon system configuration and control required, decide which control signal Inputs and Outputs (i.e.,
remote start/stop, 4-20mA in/out, etc.) will be used for your pump application and make the appropriate digital
and analog connections. See details of control connections below.
5.3.3.2 Routing
Signal wiring is routed through the two leftmost unused conduit openings Figure 5-2 – NEMA 4x 230/480
VAC Controller Layout and Dimensions at the base of the MPC VECTOR (NEM4x enclosures, panel version
based upon on conduit entry). All input/output signals are connected to the terminal strip at the edge of the
MPC VECTOR circuit board. Use caution to observe proper wire location and signal polarity. Wires should
be routed within the enclosure in a manner that maintains separation between high voltage and low voltage
conductors. Ensure all low voltage wiring is installed per any applicable local and national electrical codes and
regulations
Unused conduit openings should be plugged as required to avoid ingress of moisture and contaminants into the
MPC VECTOR enclosure. Do not remove the factory provided plug from openings that are not required for
field wiring.

5.3.3.3 Suggested Cable
Utilize 16 to 22 AWG stranded, 250 V shielded cable with a 75
input and output wiring. Recommended strip length is 0.39" or 10 mm.

The MPC VECTOR terminal strip mapping is shown in Figure 5-8 –I/O Terminal Strip Details
(Panel & NEMA4x Shown). The terminal strip is composed of 5 major connection areas:
See the appropriate control wiring sections for example I/O wiring and terminal strip locations. Customize the I/O
wiring for your pump configuration.
