Purpose and Applicability
The purpose of this document is to detail the operation instructions for the Matrix 1RU High Power DC Distribution Center. This
document applies to Comm/net part number 016-131-10 r01 and r02 with firmware version v2.0.
Unpacking and Inspection
The Matrix panel was carefully packaged at the factory to withstand the normal rigors of shipping. However, you should carefully
inspect the box and contents to confirm that no damage occurred in transit. Most shipping carriers require notification of shipping
damage within twenty-four hours of delivery, and it is the responsibility of the recipient to inspect the shipment immediately upon
receipt.
Contents
Reversible Rack-Mount Ears for 19” or 23” Racks
Rear Cover Breaker Extraction Tool
If you ordered a compliment of breakers along with your panel,
they will also be packaged along with the panel:

Installation
To install the Matrix panel, follow these steps:
1. Select the equipment rack location for installation of the panel. Orient the rack mount ears appropriately for a 19”
or 23” rack. For flush mounting, install the rack mount ears using the included Phillips head screws through the two
holes near the front of the panel. To offset-mount the panel such that the front protrudes beyond the front plane of the
rack, use the two holes further back on the sides of the panel.
2. Install the chassis ground cable. A chassis
ground cable should be landed on the two
studs marked Chassis Ground on the left
side of the panel.
3. Install the incoming DC feeder cables for
the A and B power inputs and A and B
power returns.
Consider installing a piece of clear
heatshrink tubing (3” diameter x 6” long)
over each of the power cables prior to
bolting the cable lugs to the bus bars.
Secure the cable lugs to the bus bars with
the included ¼”-20 x 1” bolts, flat washers,
lock washers, and nuts. The bus bars have
a hole and a slot to allow for ¾” or 1” bolt
hole spacing.

4. Install alarm wiring. On the left side of the
panel, there is an 8p8c modular jack (RJ-45)
for alarm connections. The pinout is:
5. Install output feeds. First, land the return cable lug to its corresponding position on the return bus bar, then land the
hot cable lug to the corresponding position above.
6. Install circuit breakers. Turn the captive panel mounting screws counterclockwise and remove the front panel. Slide a
circuit breaker of sufficient ampacity into the position corresponding to the output channel to be fed (viewing the front
of the panel from left to right, the positions are A1, A2, A3, A4, A5, A6, A7, A8, then B1, B2, B3, B4, B5, B6, B7, B8). Push
until the circuit breaker terminals are fully seated in the sockets.
Installation Checklist
Rack mount ears mounted securely to the panel and the rack?
Chassis ground cable connected?
Input power cables (A Hot, A Return, B Hot, B Return) securely bolted to the correct bus bars and heat shrink installed?
Alarm cable connected and wired correctly to remote monitoring device (if required)?
Output feed cables landed to correct polarity?
Wire lacing or cable ties installed to provide strain relief?
Breakers installed in the correct positions and fully seated?

Layout and Function of Logic PCB Interface
1. Breaker Inventory LED
Upon first power-up, the Breaker Inventory LED will flash to indicate that there is no breaker inventory present in nonvolatile
memory, and that a breaker inventory should be taken before the panel is put into service. When the Breaker Inventory button is
pressed and held, this LED will light until the breaker inventory is stored in nonvolatile memory. The LED will then report the
breaker inventory by flashing once for each breaker.
2. Breaker Trip LED
The red Breaker Trip LED will light if an inventoried breaker has tripped, or if a new breaker has been turned on since the last
breaker inventory was taken.
3. Breaker Inventory Button
The Breaker Inventory Button, when held for more than five seconds, is used to store the breaker inventory in nonvolatile
memory. The button may also be used to temporarily silence, indefinitely disable, or re-enable the beeper (see To Temporarily
Silence the Breaker Trip Alarm Beeper below).
4. B Input Power LED
The B Input Power LED will light when power is present on the B input bus.
5. A Input Power LED
The A Input Power LED will light when power is present on the A input bus.
6. Reset Button
In the unlikely event that a power anomaly or static discharge causes improper operation of the microprocessor, the Reset button
may be used to reset the microprocessor. The breaker inventory is not affected. However, when used in combination with the

Breaker Inventory button, the Reset button may be used to reset the nonvolatile memory to factory defaults (see Factory Reset
below).
To Inventory the Circuit Breakers
1. From the factory, when power is applied to the panel for the first time, the blue Breaker Inventory LED will flash at
about a one second interval. This indicates that it is necessary to inventory the circuit breakers that are installed in the
panel.
2. Turn on all the circuit breakers that are installed in the panel. Press and hold the Breaker Inventory button. Hold the
button down until the blue Breaker Inventory LED turns on, then subsequently turns off (about five seconds). This
indicates that all of the breakers that are installed and turned on have been inventoried and saved to the non-volatile
memory of the microprocessor. The Breaker Inventory LED will then report the number of inventoried breakers by
flashing once for each breaker that is installed.
3. Check the inventory and the breaker trip indicator function by sequentially turning off each circuit breaker one at a
time. When a breaker is turned off the red Breaker Trip LED will turn on and the alarm beeper will sound. When the
breaker is turned back on, the LED will turn off and the alarm beeper will silence.
4. The breaker inventory will remain in non-volatile memory even if the unit is de-powered.
5. If a new breaker is installed at a later date, the red breaker trip LED will turn on, indicating that a new inventory must
be taken.
To Temporarily Silence Breaker Trip Alarm Beeper
1. To silence the breaker trip alarm beeper, tap the Breaker Inventory button momentarily (press until the blue
breaker inventory LED turns on, then release). [Note: the logic PCB only recognizes a momentary tap when the
breaker inventory button is released after the blue breaker inventory LED has turned on.]
2. The breaker trip alarm beeper will silence.
3. The breaker trip alarm beeper will re-engage if an additional breaker is tripped, or if the tripped breaker is reset and
re-trips.
To Disable/Re-Enable the Breaker Trip Alarm Beeper
1. To prevent the breaker trip alarm beeper from sounding on any breaker trip, momentarily tap the breaker inventory
button (press until the blue breaker inventory LED turns on, then release) four times in a row.
2. The breaker trip alarm beeper will not sound when a breaker is tripped.
3. To re-enable the breaker trip alarm beeper, repeat step 1.

To Perform a Factory Reset
1. To perform a full factory reset (erasing all breaker inventory and alarm settings), hold the breaker inventory button
and momentarily tap the processor reset button.
2. Continue holding the breaker inventory button until the blue Breaker Inventory LED turns off.
3. When the breaker inventory button is released, the blue breaker inventory LED will be flashing, indicating that the
factory reset was successful.
Panel and Breaker Rating Limitations
•The panel is rated for a maximum current of 300A per bus.
•The sum of the eight distribution breakers on either side of the panel may not exceed 300A.
•The maximum rating for any single breaker position is 100A.
•As of the publication date of this document, the 80A and 100A Heinemann Slimline 1RU circuit breakers are not UL
approved.
Breaker Removal
The Breaker Extraction Tool
The breaker extraction tool is designed to connect to the front of the slimline
breakers compatible with the panel.
The breaker extraction tool is equipped with a magnet for convenient storage of
the tool when not in use.

SETUP AND OPERATION MANUAL
Page 8
With the magnet in place, the breaker extraction tool is designed to attach directly
to the metal chassis of the panel. When not in use the breaker extraction tool
should be attached to the front of the panel for direct and consistent access.
Extracting Slimline Breakers
Each slimline breaker has two threaded brass screw hole features designed for
extraction.
The breaker extraction tool is fitted with screw features designed to attach to the
breaker. Attach the breaker extraction tool to the front of the breaker with these
screws.
Attach the breaker extraction tool to the front of the slimline breaker.
With your finger on the breaker extraction tool, slowly pull the breaker extraction
tool directly away from the breaker panel to release the breaker from the panel.
