1 PRODUCT DESCRIPTION
This section describes the functions and features provided by the PowerWorx Select Series
circuit breaker panel and provides a table of product specifications.
1.1 Product Functions and Features
The Select Series circuit breaker panel, shown on the cover of this manual, supplies protected
dc power to the –24 Vdc and –48 Vdc powered equipment typically installed in a central office,
multimedia headend, remote site, CEV, or other restricted access location. The panel provides
the following basic functions and features:
• Self-configuring voltage (–24 Vdc or –48 Vdc) capability to simplify installation and
allow one panel to fit most dc voltage applications.
• Ampere ratings and ON/OFF designations clearly marked on each circuit breaker.
• Eight single-pole circuit breaker mounting positions (two-pole breakers require two
mounting positions) per bus.
• Two sets of mounting brackets to permit panel installation in a 19- or 23-inch, WECO or
EIA, equipment rack.
ADCP-80-545 • Issue 3 • March 2006
• Mounts within 1 rack space (1.75 inches).
• Dual-bus power feeds with a maximum input rating of 100 Amps per bus.
Warn ing: Use of one bus only on a dual bus panel will result in false alarms for the unused
bus. Power is required on both buses on a dual bus panel for normal operation.
• Two-hole compression-lug style terminals for input power connections. Screw-down
barrier terminal strips for output power connections.
• Screw-down or wire-wrap pin terminals (option) for alarm connections. A tripped breaker
or loss of power initiates relay operation which opens one set of relay contacts (form C)
and closes another set. The alarm contacts may be used to open or close a loop connected
to an external alarm system.
• Two field-replaceable high-brilliance power indicators (green LED’s) and two nonreplaceable high brilliance alarm indicators (red LED’s).
• Two grounding studs to ensure reliable ground connectivity.
• Easy to remove/replace plastic protective covers mount over the input and output terminal
connections to enhance safety.
1.2 Circuit Breaker Panel Components
The panel consists of the components shown in Figure 1. Panel components are either mounted
on or housed within a putty white powder-painted sheet metal enclosure. The circuit breakers,
the power LED indicators, and the breaker alarm LED indicators are mounted on the front side
of the enclosure. Unused circuit breaker mounting positions are covered with blanks.
Replacement circuit breakers, lug terminals, a cable management bar, and other items are
available separately as accessory items.

to the panel, the rack, or a location close to the panel. The cards insert into the card holder.
Two types of cards are provided.
1.6 Mounting
The Select Series circuit breaker panel can be mounted in either a 19- or 23-inch (482.6 or
584.2 mm) equipment rack. Two sets of mounting brackets, one set for 19-inch racks and one
set for 23-inch racks, are provided with the panel. The panel can be flush mounted or recessed 1,
2, 3, or 4 inches (25.4, 50.8, 76.2 or 91.6 mm). The mounting brackets are slotted to allow the
panel to be mounted in racks with WECO 1.0-inch (25.4 mm) or EIA 1.25-inch (31.8 mm) hole
spacing. The slots also compensate for vertical rack differences so that the panel can be
mounted in either 1.75- or 2-inch (44.5 or 50.8 mm) rack spaces. The panel requires one open
rack space above and below the chassis for heat dissipation.
1.7 Power Buses
The Select Series circuit breaker panel has two isolated power bus (power feed) circuits which
are designated as the A and B power buses. Each power bus circuit distributes the input power
to the corresponding A or B output power circuit. In each bus circuit, current flows from the
input power terminals, through the circuit breakers, to the output power terminals.
ADCP-80-545 • Issue 3 • March 2006
Warn ing: Use of one bus only on a dual bus panel will result in false alarms for the unused
bus. Power is required on both buses on a dual bus panel for normal operation.
The maximum current capacity of each power bus circuit is 100 Amps. The total output current
capacity of the circuit breakers on each bus must not exceed 100 Amps. The maximum current
rating is marked on the circuit breaker panel rear side. The power dissipation of the panel is 160
watts maximum per panel (80 watts per bus).
1.8 Circuit Breakers
The circuit breakers are magnetic actuation, manual reset, replaceable, 60 Vdc rated circuit
breakers, with finger guard and ampere markings. Both 1- pole and 2-pole breakers are used
with the panel. The 1-pole breakers are available with 1, 3, 5, 10, 15, and 20 Amp ratings. The
2-pole breakers are available with 26, 30, 36, 40, and 50 Amp ratings. Each 1-pole or 2-pole
circuit breaker can be field-replaced by another 1-pole or 2-pole breaker with a different current
rating or time delay. A breaker with a higher current rating may be installed as a replacement as
long as the total current draw of the affected bus does not exceed 100 Amps.
The circuit breaker panel will accommodate from one to eight 1-pole circuit breakers per bus or
from one to four 2-pole circuit breakers per bus. Both 1-pole and 2-pole breakers may be
combined together on the same bus. Each circuit breaker position that does not have a breaker
installed will be filled with a black plastic plate. Any circuit breaker mounting positions that are
left blank when the panel is ordered cannot be fitted with field-installed circuit breakers.

The circuit breakers are of the type called “short delay.” The trip times of short delay circuit
breakers are a function of the percent of rated current, as indicated in Table 1. The circuit
breaker will trip (open) and the switch will move to the off position (bottom pushed in) when
the circuit current exceeds the capacity of the circuit breaker. To reset a circuit breaker, push the
switch to the on position (top pushed in).

1.13 Alarm Operation and Connections
The Select Series circuit breaker panel contains circuitry that opens and closes a set of form C
relay alarm contacts when a circuit breaker trips or when power to either power bus is lost.
These contacts may be used to open or close a loop connected to an external alarm system.
During normal operation (power applied), the normally open (NO) contacts remain open and
the normally closed (NC) contacts remain closed. When a circuit breaker trips or when power to
a power bus is lost, the NO contacts close creating a connection between NO and common (C)
terminals; and the NC contacts open creating an open circuit between NC and C terminals. The
rating for the alarm relay contacts is 110 Vdc/125 Vac maximum voltage, 1.0 Amp maximum
switching current.

Verify that the alarm contacts are functioning properly. With power applied and all circuit
breakers in the OFF position, the alarm contacts should be in the alarm state. Using a multimeter
that is set to test for continuity, connect the probes alternately between the C and NC terminals
and the C and NO terminals for both sets of alarm terminals. Verify that no continuity exists
between the C and NC terminals and that continuity does exist between the C and NO terminals.

5 OPERATION
Operation of the Select Series circuit breaker panel consists of placing circuit breakers in either
the ON or OFF position, replacing breakers that fail or that need upgrading, and connecting new
equipment to the output power circuits. If a breaker trips, the alarm LED indicator for the
corresponding power bus lights and the external alarms are activated (if present).
Warn ing: The circuit breaker panel uses electrical voltage and current levels that may be
considered an electrical hazard per GR-1089. Only qualified personnel should be allowed to
install, operate, maintain, or otherwise come into contact with this equipment when energized.
Only insulated tools should be used on energized elements of the panel.
5.1 Circuit Breaker Operation
Each circuit breaker is equipped with a rocker-type ON/OFF switch handle. To turn on the
power to the protected equipment, place the circuit breaker handle in the ON position. To turn
off the power to the protected equipment, place the circuit breaker handle in the OFF position.
The circuit breaker will automatically trip (turn off) when the load current exceeds the current
rating of the breaker
ADCP-80-545 • Issue 3 • March 2006
For the initial power-up of the protected equipment, it is recommended that the voltage level at
the equipment be tested. Using a multi-meter that is set to measure DC voltage, verify that the
output voltage at the protected equipment is a nominal –24 Vdc or –48 Vdc (whichever applies)
and the polarity of the BATT (–) and RTN (+) lead wires is correct. Perform this test for all
output circuits. When all the circuit breaker handles are placed in the ON position, the
BREAKER ALARM indicator will go out and the alarm contacts will return to the normal state.
Note: All circuit breakers, even those not connected to a load, must be placed in the ON
position in order to make the BREAKER ALARM indicators go out and to return the
alarm contacts to the normal state.
When a circuit breaker trips, the BREAKER ALARM indicator on the corresponding power bus
will light and the handle on the tripped breaker will move to the OFF position. To determine
which breaker tripped, locate the breaker handle that is in the OFF position. Determine what
caused the breaker to trip and take the appropriate corrective action. When the problem has been
corrected, place the breaker handle in the ON position. The BREAKER ALARM indicator
should go out and the alarm contacts should return to the normal state.
5.2 Connecting New Equipment
New equipment may be connected to unused circuit breakers following installation and testing
of the circuit breaker panel. Use the following procedure for connecting the output power wires
for new equipment to an unused output circuit:
Warn ing: The circuit breaker panel uses electrical voltage and current levels that may be
considered an electrical hazard per GR-1089. Only qualified personnel should be allowed to
install, operate, maintain, or otherwise come into contact with this equipment when energized.
Only insulated tools should be used on energized elements of the panel.

1. Remove the plastic protective covers from the rear side of the output power terminal
blocks (refer to Section 3.7, Protective Cover Installation/Removal).
2. Locate an unused pair of output power terminals and verify that a circuit breaker of the
recommended size and type (as specified by the equipment manufacturer) is installed the
corresponding breaker mounting position.
3. Place the circuit breaker handle in the OFF position.
Note: Placing the circuit breaker in the OFF position will cause the BREAKER ALARM
indicator for the corresponding power bus to light and will cause the alarm contacts to
move to the alarm state.
4. Connect the output power wiring to the power output terminals as described in
Section 3.5, Output Power Connections. Copper wire in sizes ranging from #8 to #22
AW G may be used for the output power wiring.
Warn ing: Use care to avoid shorting out adjacent terminals when connecting new output
power wiring to a powered circuit breaker panel. Shorting may cause injury and damage the
panel or the connected equipment.
5. Re-install the plastic protective covers over the output power terminal block (refer to
6. Place the circuit breaker handle in the ON position and verify that the voltage level and
6 MAINTENANCE
Warn ing: The circuit breaker panel uses electrical voltage and current levels that may be
considered an electrical hazard per GR-1089. Only qualified personnel should be allowed to
install, operate, maintain, or otherwise come into contact with this equipment when energized.
Only insulated tools should be used on energized elements of the panel.
6.1 Inspection
Inspect the circuit breaker panel periodically (every six months is recommended) for damage to
the breakers and for damaged or broken wires at the power and external alarm connections. If
excessive dirt is found during the inspection, brush or wipe dust and dirt from the panel with a soft
bristle brush or soft cloth. Take care to avoid damaging the breakers or wiring. Broker or
damaged circuit breakers should be replaced (see Section 6.3, Circuit Breaker Replacement). If
a circuit is not operating properly, contact ADC Customer Assistance (see Section 7, Customer
Information and Assistance).
Section 3.7, Protective Cover Installation/Removal).
polarity are correct (refer to Section 5.1, Circuit Breaker Operation).
6.2 Power LED Indicator Replacement
The power LED indicators may be field-replaced if they fail. Use the following procedure to
replace a failed LED indicator:
1. Pull the LED indicator slowly out from the front of the panel.
Page 24

ADCP-80-545 • Issue 3 • March 2006
Note: The LED indicator uses a snap-in type retainer to hold it in place on the front side of
the panel.
2. Use a needle-nose pliers to disconnect the lead wire terminals (quick-connects or fastons)
from the metal tabs on the rear side of the LED indicator as shown in Figure 17.
Note: The lead wire terminals are insulated and can generally be removed without turning
off the power to the circuit breaker panel. If any part of the terminal is not covered by
insulation, make sure the exposed portion does not come into contact with the panel
chassis or the other terminal.
3. On the replacement LED indicator, connect the red wire to the tin tab and the black wire
to the brass tab.
4. Push the LED indicator back into the panel until it snaps into place.

6.3 Circuit Breaker Replacement
Any existing circuit breaker may be field-replaced with an identical circuit breaker or with a
breaker that has a different current rating or time delay. However, a breaker with a higher
current rating may only be used as a replacement if the total current draw of the affected bus
will not exceed 100 Amps. A circuit breaker mounting position that does not have an existing
breaker (blank) cannot be used for installation of a replacement breaker. Use the following
procedure to replace an existing circuit breaker with a new breaker:
Note: Previous versions of the Select Series Circuit Breaker Panel were not equipped with
field-replaceable circuit breakers. If the panel does not have a slot above the circuit
breakers as shown in Figure 18, then it does not have field-replaceable circuit breakers and
this procedure does not apply.
1. Turn-off or disconnect the power from the power bus (either A or B) that supplies current
to the circuit breaker to be replaced.
Danger: During normal operation, the terminal connections on the circuit breakers are
electrically energized. Failure to disconnect the power from the power bus that supplies current
to the circuit breaker being replaced may cause severe personal injury to the installer and/or
equipment damage.
