Installing Optional DC Breakers

The MPSL-30D, MPSL-60S and MPDH-30D enclosures provide the room to install additional DC
circuit breakers that may be used for charge controllers, a PV-GFP device, and other DC loads.
These enclosure have been specifi cally designed to allow both back-mounted (1” wide)

1

or DIN

rail-mounted (1/2” wide)

breakers.

CAUTION: Turning the inverter DC disconnect breaker off only removes the battery
power to the inverter, it does not interrupt power from the battery to the DC load
breakers. This must be accomplished by turning off the DC load breakers themselves.
Therefore, to shut the system off completely, all of the breakers in the MP enclosure
should be switched to the OFF position.

Installation Instructions - DC Load Breakers:

1. Remove the front cover of the MP enclosure.

2.

For DIN rail-mounted breakers
(refer to Figure A6-1):

For back-mounted type breakers
(refer to Figure A6-2):

a. Install the breaker(s) on the DIN rail mounting
track, and slide them all the way to the left side.
b. Place a DIN rail clamp against the right side of
the last circuit breaker; and tighten this clamp to
secure the breaker(s) on the DIN rail track.
c. For each breaker installed, remove only 1
knockout (= 1/2” slot) in the front cover.

a. Remove the DIN rail mounting track by
unscrewing the #8, Truss head, T15 Torx
drive screws.
b. Secure the breaker(s) to the breaker
mounting panel using two #8 screws
(minimum 1/2” length).
c. For each breaker installed, remove only
2 knockouts (= 1” slot) in the front cover.

3. Ensure the breaker(s) align correctly into the spaces made by the knockouts removed from the

front cover (see Section A8).

4. Wire the breaker(s) to the DC circuit (see Figure A6-3).

5. Replace the MP’s front cover and check that the breaker operates correctly.

Note 1 - For the 1/2” wide DIN rail-mounted breakers, use Q-Frame types (QYN Series by CBI).
Note 2 - For the 1” back-mounted breakers, use E-Frame types (E Series by Carling Technologies,
209 Series by Airpax/Sensata Technologies or CF Series by Heinemann/Eaton).
