Wait a minimum of 5 minutes after disconnecting power before servicing the MPC or pump motor. Capacitors retain
a charge even after power is removed from the controller.
1.
Remove the screws that are securing the cover of the main unit.
2.
CAUTION: The cover is wired and should be opened gently being sure not to pull any of the wires that are
connected to it.
3.
Make a note of what color lead is in each position of the terminal block “J14”. Unscrew each screw on the
terminal block “J14” and remove each lead.
4.
Loosen the outer domed nut on the liquid tight, releasing the tension on the cable. Pull the cable through the
liquid tight. Thread the new cable through the liquid tight with enough length to reconnect to the terminal
block.
5.
Prepare the end of the cable as per
Figure 7
on the following page. Ensure that the shield is fully insulated
until the point where it enters the terminal. No part of the shield should be allowed to come in contact with
the circuit board, equipment case, or any other surface.
6.
Note that the black-green lead should be paired with the green wire.
7.
Referring to the notes taken earlier, connect each lead of the new cable to the proper position of the terminal
block, and then lock the lever back in place to hold lead. NOTE: It is recommended that you insert and secure
one lead at a time.
8.
Tighten the dome nut of the liquid tight to secure/seal cable.
9.
Replace cover carefully being sure not to crimp any of the cables/leads between cover and enclosure and
tighten screws.
10.
Power the unit on, if all connections were properly made the unit will power as normal and the display will
show the start up screen.
