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.

4.0 SAFETY & INDUSTRY STANDARDS
4.1 DPBF1U&DPGF1USeries powerdistribution panelsmeet thefollowing safetyrequirements:
STANDARD
UL60950-1, 2nd Edition
CSA22.2 No. 60950-1, 2nd Edition
EN60950-1, 2nd Edition
4.2 DPBF1U&DPGF1USeriespowerdistributionpanels areCEmarkedtoindicateconformance
to the European Union’s Low Voltage Directive.
4.3 These Distribution Panels operate at voltages that could potentially be hazardous.
Furthermore, inadvertent short circuiting of the system battery and/or rectier by mis-
connection or other error could be harmful. This product should be handled, tested and
installed only by qualied technical persons who are trained in the use of power systems
and are well aware of the hazards involved.
4.4 When operating this Distribution Panels the chassis ground terminal must be connected to
the system frame ground or other proper safety ground for the protection of personnel.
4.5 All connections to the Distribution Panels should be carefully checked for errors before
applying power to them.
4.6 The internal voltages may be at hazardous potentials. The top cover should not be removed.
There are no user-serviceable components in these units. Removing the top cover will void
the warranty.
5.0 WARRANTY (summary)
DPBF1U & DPGF1U Series power distribution panels are warranted for two (2) years from date of
shipment against defects in material and workmanship. This warranty does not extend to products
which have been opened, altered or repaired by persons other than persons authorized by the
manufacturer or to products which become defective due to acts of God, negligence or the failure

6.0 DESCRIPTION OF OPERATION
6.1 Power Distribution Circuits. A simplied schematic diagram of the distribution panels
is shown in Figure 2. The battery input to each load connects to a high-current copper bus
bar from which the individual fuses or circuit breakers distribute power to the loads. The
return input connects to a similar bus bar to which the individual loads terminate. The A
and B loads are totally independent and isolated with the exception of models incorporating
the ‘S’ option.

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.
