Operation
Set-Up
The recommended procedure for setting up the MPC is the following:
• Make sure the AC BREAKER on the rear panel of the MPC is in the OFF position.
• Connect the ground wire to the ground stud on the rear panel of the MPC.
• Connect all OUTPUT cables, first to the MPC and then to the various loads.
• VERIFY that the DC OUTPUT cable is connected to the MPC and the load with the correct
polarity.
• Connect the USER I/O cables.
• Connect all INPUT cables, first to the MPC and then to the various sources.
• An overcurrent protect and disconnect device should be installed on the DC INPUT
circuit. An example of a suitable device is a Carling Technologies, C‑series, 80 A 65 VDC,
CA1‑B0‑14‑680‑321‑J circuit breaker. (www.carlingtech.com)
• VERIFY that the DC INPUT cable is connected to the MPC and the source of DC power with
the correct polarity.
• Turn on the sources (if they have an upstream breaker).
• Move the AC BREAKER on the rear panel of the MPC to the ON position.
Note: Be careful to not toggle the ON/OFF switch during the setup. Doing so could cause the
MPC to turn on and present a hazardous voltage at its output.
