Page 18: Use Of Screws In Accessories Package
Screws to Attach Brackets to Rack To fasten the brackets to the rack, use the nickel plated 12-24 screws as shown in Figure 9 (2 for each bracket). Four screws are in the package. Page 18 © 2006, ADC Telecommunications, Inc. -
Page 19: Protective Cover Installation/Removal
Slide the cover to the right and then pull the cover directly outward and away from the panel. The screws do not need to be completely removed to remove the protective cover. Page 19 © 2006, ADC Telecommunications, Inc. -
Page 20: Cable Management Bar (Optional Accessory For Circuit Breaker Panels)
Use of any other hardware could cause contact with internal parts of the circuit breaker panel. If parts are missing, please contact ADC. Note: A circuit breaker panel with the cable management bar attached may exceed the 12-inch (3.05 mm) overall depth objective described in GR-63 CORE, 02-14. -
Page 21: General Wiring Recommendations
Figure 13. After routing the cables, tie them to the cable management bar (if optional accessory ordered). Caution: Connect both buses of the circuit breaker panel to only –24 Vdc or –48 Vdc. Page 21 © 2006, ADC Telecommunications, Inc. -
Page 22: Chassis Ground Connection
This provides an adequate return path capable of allowing the circuit breaker to fail in the unlikely event of a battery wire to chassis fault. Page 22 © 2006, ADC Telecommunications, Inc. -

#16 to #30 AWG wire with crimp-on spade lug or ring connectors that have a maximum width of 0.200 inches (5.080 mm) or use #16 to #30 AWG wire without lugs (see Figure 15). Tighten the screws to approximately 9 pound-force inches (1 Newton-meter) of torque. Page 23 © 2006, ADC Telecommunications, Inc. -
Page 24: Output Power Connectors
0.325 inches (8.255 mm). • The terminals also accommodate copper wire without lugs (insulation stripped back). • Tighten the screws to approximately 9 pound-force inches (1 Newton meter) of torque. Page 24 © 2006, ADC Telecommunications, Inc. -
Page 25: Input Power Connectors
Tighten the nuts to approximately 16 pound-inches (1.8 Newton meters) of torque. Replace the protective cover on the circuit breaker panel after all the wiring connections are made and before power is applied to the panel (refer to Subsection 4.3, Protective Cover Installation/Removal).

Only insulated tools should be used on energized elements of the panel. Page 27 © 2006, ADC Telecommunications, Inc. -
Page 28: Maintenance
Care should be taken to not damage the circuit breakers or any wiring. Adjustments No adjustments in the field are indicated or required. If a circuit is not operating properly, contact ADC customer assistance (see Section 8, Customer Information and Assistance). Power-On LED Replacement The circuit breaker power-on indicator LEDs may be replaced as follows: 1. -
