P
prevent elevtrical shock and equipment damage.
The MPC-4C0 is powered on when connected to
a functional MSGMPC. No additional power is
required.
INSTALLATION
The MPMCO is a printed circuit board that fits
into any of the four option slots on the
MSGMPC. To install, remove power from the
MSGMPC and insert the MPG4CO into the
desired option slot on the MSC-MPC. Wiring
instructions , diagrams, and software assignments
are provide below.

WIRING INSTRUCTIONS AND
SETUP INFORMATION
Contact Inputs
The contact input circuitry on the MPC-4CO
accommodates normally open dry contact inputs
for monitoring status. These contact inputs
cannot be used for pulse monitoring. Terminate
the white wire(positive) to terminal A, the black
wire (negative) to terminal B, and the shield to
any convenient ground screw in the enclosure.
Cut and tape the shield at the field device. Refer
to Figure 2 below.
Status feedback for loads controlled by the
MPC-4CO must be terminated to the same
MSGMPC that originates the control action.
Do not attempt to power the unit ON until
installation is complete.
