DCPDU2B SERIES DC POWER DISTRIBUTION PANELS
1.0 INTRODUCTION
DCPDU2BSeries circuitbreakerpanels providedistributionand overloadprotectionfor 1to20 circuits
with circuit breakers that can be eld installed/exchanged using a supplied puller tool. The panels
are only two mounting positions (3.5 inches) high.
The panels provide up to 20 breakers single bus 450A or 10A+10B 450A+450A distribution and
alarm capabilities. The A and B sections of the dual-bus panel are fully isolated, can be separately
congured for 24/48 volts and are polarity neutral. Breaker capacities range from 2.5 to 200 amperes.
Breaker alarm is indicated by a dual color LED (green/red) and Form C relay contacts for each bus.

4.0 SAFETY & INDUSTRY STANDARDS
4.1 DCPDU2B Series power distribution panels meet the following safety requirements:
STANDARD
UL60950-1, 2nd Edition
CSA22.2 No. 60950-1, 2nd Edition
EN60950-1, 2nd Edition
4.2 DCPDU2B Series power distribution panels are CE marked to indicate conformance
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 rectier by mis-
connection or other error could be harmful. This product should be handled, tested
and installed only by qualied 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 Allconnectionsto theDistributionPanelsshould becarefullychecked forerrorsbefore
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)
DCPDU2B 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 of customer to fully follow instructions with respect to installation,
application or maintenance.

6.0 DESCRIPTION OF OPERATION
6.1 Power Distribution Circuits. A simplied 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 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.

8.0 FRONT PANEL DESCRIPTION
The front panel of the DCPDU2B, shown in Figure 3 below, consists of the A and B sides
and a center section. The A and B sides can each accommodate up to 10 eld installed/
replaceable hydraulic magnetic circuit breakers rated from 2.5A to 200A. The center section
has two green/red LEDs, one for the A side (left) and the other for the B side (right). At the
bottom of this center section is a slot for a wallet and designator card. This card permits the
recording of each output circuit by number.

9.4 Output Connections. Output connections for A and B loads are shown in Figure 4.
There are 10 sets of bus bar terminals for each side, Aand B. The connections are
numbered to correspond with the numbers of the front panel breakers. The upper
strip connections are from the battery (FEED) through the breakers; the lower strip
connections are the RETURNS. Side B is on the left and side A on the right when
viewed from the rear.
All connections use 1/4-20 threaded studs and are rated up to 100 amperes. Maximum
wire size is 2 AWG. Transtector recommends using FLEX wire with either Panduit
LCDXN2-14A-E or LCDXN2-14AF-E (90deg angle) lugs. When 125A, 150A or 200A
breakers are installed two positions are utilized. Figure 6 below shows detailed
spacing of the terminals.
