3.2 Mounting Procedure
The circuit breaker panel can be mounted in either a 19- or 23-inch wide rack. Two sets of
mounting brackets are provided with the panel. Eight 5/16-inch (7.94 mm) long, thread-
forming, Phillips-drive, 8-32 flat-head screws are provided for attaching the mounting brackets
to the panel. Four 3/8-inch (9.53 mm) long, Phillips-drive, 12-24 pan-head screws and four #12
flat washers are provided for attaching the mounting brackets to the equipment rack.
Use the following procedure to install the circuit breaker panel in the equipment rack:
1. Select the 19- or 23-inch mounting brackets (whichever set is required) and orient for
installation as shown in Figure 7 .
2. Attach the brackets to the sides of the circuit breaker panel chassis using the eight 5/16-
inch (7.94 mm) 8-32 flathead thread-forming screws provided. Tighten screws to 15 pound
force-inches (1.7 Newton meters) of torque to insure grounding.
3. Place the panel in the specified mounting space within the rack as shown in Figure 8 .
4. Secure the panel to the rack using the four 3/8-inch (9.525 mm) long 12-24 pan-head
screws and #12 flat washers provided (use star washers when required by local practice).
Tighten the screws to 27 pound-force inches (3.1 Newton meters) of torque to insure
grounding.
Caution: When attaching the mounting brackets to the circuit breaker panel, use only the 5/16-
inch (7.94 mm) long, thread forming, flathead screws provided with the panel. Use of any other
hardware could cause contact with internal parts of the panel. If parts are missing, contact
ADC to order replacement parts.
Note: Provide one rack unit of space above and below the panel for air circulation.
