DC POWER DISTRIBUTION PANELS
1.0 INTRODUCTION
These distribution panels provide protected power distribution to telecommunication equipment.
They oer fuse or circuit breaker positions on the A and B sides of the panel. The A and B loads
of the distribution panel are totally independent and isolated from each other. There is a green/red
LED for each load to indicate normal operation or an open circuit due to a blown fuse or tripped
circuit breaker.
The panels areonly 1.75 inches (1mounting position) high tominimize rack space andcan be mounted
in either a 19- or 23-inch relay rack with corresponding brackets. They can be mounted from the
front of the rack with osets every ¼-inch from front to back to align with existing rackmounted
equipment.
Figure 1 shows the two series of panels. The rst is the DPGF1U Series which has 4 or 6 GMT
fused circuits on bothAand B sides. The second is the DPBF1U Series with up to 4 circuit breaker
circuits on both A and B sides.

The panels can be congured for 12, 24 or 48 volts with either positive or negative ground. Because
the A and B sides are independent and isolated, they can be congured separately. For example,
theAside can be 48V positive ground and the B side can be 24V negative ground. The voltage and
polarity of each side must be congured at the factory. All models are reverse polarity protected.
Each bus (Aand B) has a green/red visual alarm and one Form C relay alarm contact for connection
to external audible or visual alarms.

6.2 Alarm Circuits. The alarm circuits detect a tripped circuit breaker or blown and, in this
event, turn on the red part of the LEDs. The alarm circuits also each drive Form C relay
contacts. If one or more circuits open or if there is an input power failure, the relays are
de-energized and the contacts are used to control external audible or visual alarms. The A
and B alarm circuits are also independent and isolated from each other.

9.4 Output Connections. Output connections for A and B loads are shown in Figure 6. There
are 10 sets of barrier terminal strip connections for each side, A and B. The connections
are numbered to correspond with the numbers of the front panel breakers. The upper strip
connections are from the battery through the breakers; the lower strip connections are the
returns. Side B is on the left and side A on the right, as shown.
Each terminal is a no. 6-32 screw and is rated at 30 amperes. Wire sizes from no. 10 AWG
up to no. 22AWG may be used for connections. Figure 7 below shows detailed spacing of
the terminals.
When DPBF1U is tted with either 40A or 50A breakers the additional load rating is
accomodated by tting adaptors that bridge two barrier strip terminals and provide a single
#10-32 screw. Minimum wire size for these connections is 8 AWG.
A maximum of two high current breakers is allowed on each bus.

Table 5. Alarm Relay Contacts
“Normally Closed” and “Normally Open” are dened with the distribution panel powered
and providing power to all outputs, i.e. no circuit breakers tripped.
The ratings of the relay contacts are 0.6A at 125VAC or 2A at 30VDC. The spring clamp
terminals accept wire sizes nos. 16 to 26 AWG.
When the input power is connected to a side (A or B), the Form C relay of that side is
energized. If there is either loss of input power, one or more circuit breakers trip or the relay
is de-energized, the normally open contacts close and the normally closed contacts open.
9.6 Chassis Ground Connection. Just below the Form C relay contact terminals is the chassis
ground terminal. This terminal is a no. 8-32 stud with a nut.
NOTE THAT IT IS ESSENTIAL THAT THIS TERMINAL IS CONNECTED TO THE
SYSTEM FRAME GROUND TO ENSURE SAFE OPERATION.

10.0 UNPACKING AND INSPECTION
10.1 This power distribution panel was carefully tested, inspected and packaged for shipment
from our factory. The unit and circuit breakers are shipped separately. Upon receipt of the
unit it should be carefully unpacked and inspected for any damage in shipment.
10.2 If there is evidence of damage, do not attempt to test the unit. The freight carrier should
be notied immediately and a claim for the cost of the rectier system should be led with
the carrier for direct reimbursement. Be sure to include the model and serial number of the
damaged unit in all correspondence with the freight carrier. Also save the shipping carton
and packing material as evidence of damage for the freight carrier’s inspection.
10.3 UNIPOWER will cooperate fully in case of any shipping damage investigation.
10.4 Always save the packing materials for later use in shipping the unit. Never ship the rectier
system without proper packing.
11.0 INSTALLATION
11.1 Mounting. This distribution panel can be mounted in either 19- or 23-inch racks by using
the supplied reversible brackets. Mount it from the front of the rack using the correct osets
to align with existing rack-mounted equipment.
The bracket osets are every quarter inch from front to back.
11.2 Connections. Input connections should be made with one- or two-terminal crimp type lugs
using copper wire size from no. 1 to 8 AWG, depending on current and wire loop distance.
See Sections 9.2 and 9.3. Output connections are made to the barrier terminal strips. See
Section 9.4 and Figure 7.
NOTE: Single feed models with option S tted have both left and right side input bus
bars tted. It is only necessary to connect the input feed to one side for correct operation.
The unused side is directly connected to the live input feed and can be used for supplying
additional panels. See gure 8 below.
CAUTION:The total load must not exceed 80A for DPGF1U or 150A for DPBF1U on any
one pair of bus bars in the chain.

The Form C relay contact output connections are made to the spring clamp terminal blocks.
See Section 9.5. The chassis ground connection is made to the no. 8-32 stud. See Section
9.6. This safety ground connection should be made before operating the panel.
11.3 CheckingConnections. Carefully checkthe polarity of input connections to the distribution
panel and output connections to the load before operating the panel. Reverse connections
will not harm the distribution panel as reverese polarity protection is incorporated. However
it may cause serious harm to the load. Check to make sure that the chassis safety ground
connection is made. Make sure that all connections are clean and secure to minimize contact
resistance.
11.4 Rear Safety Cover. Once all of the above have been completed, t the clear plastic safety
cover to the back of the unit using the supplied mounting studs and screws. Instruction for
tting the mounting studs the panel are included in the accessory kit.
12.0 SETUP AND TESTING
12.1 It is not necessary to have the distribution panel mounted in a rack for initial testing. This
can be done on a bench. It is also not necessary to have loads connected to the panel for
this testing.
12.2 With the input power source o, connect the input wires to the A side of the distribution
panel. Connect ground to the chassis ground terminal. Insert all fuses into fuse holders or
set all circuit breakers to on.
12.3 Turn on the input power source. The A side LED should be green. If it is red, one of the
fuses is blown or a circuit breaker is tripped. If the LED is o, there is no input power to
the unit. Check the output voltage at each set of output terminals with a digital voltmeter.
12.4 With the A side LED green, use an ohmmeter to check the Form C relay contact outputs.
On the upper row of the wire-wrap terminals (sideA) measure the resistance between pins 1
and 2 and between pins 4 and 5. Both should read “short”. Measure the resistance between
pins 2 and 3 and between pins 5 and 6. Both should read “open”.
12.5 On the A side insert a blown fuse into fuse no. 1 position or trip circuit breaker no. 1. The
A side LED should turn red. On the upper row (side A) of wire wrap terminals, measure
the resistance between pins 1 and 2 and between pins 4 and 5. Both should read “open”.
Measure the resistance between pins 2 and 3 and between pins 5 and 6. Both should read
“short”. Replace the blown fuse with a good one or reset the circuit breaker.
12.6 On the A side check each succeeding fuse by replacing it with a blown fuse, or breaker by
tripping it, and verify that the LED turns red. It is not necessary to recheck the Form C
relay contacts.
