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.

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

AWG may be used for the output power wiring.

5. Re-install the plastic protective covers over the output power terminal block (refer to

Section 3.7, Protective Cover Installation/Removal

).

6. Place the circuit breaker handle in the ON position and verify that the voltage level and

polarity are correct (refer to

Section 5.1, Circuit Breaker Operation

).

MAINTENANCE

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

).

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.

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.

Warning: 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.

Warning: 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.
