Use the following procedure to install the circuit breaker panel in the rack:
1. Select either the 19-inch or 23-inch brackets.
2. Attach the mounting brackets to the sides of the chassis using the eight 5/16-inch (7.94
mm) 8-32 flathead thread-forming screws provided. Tighten the screws to 15 pound-force
inches (1.7 Newton meters) of torque to insure grounding. Refer to Figure12.
Figure 12. Repositioning the Mounting Brackets (Optional)
3. Place the circuit breaker panel in the specified mounting space within the rack as shown in
Figure 13.
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.
Caution: When attaching the mounting brackets to the circuit breaker panel, use only the
5/16-inch (7.935mm) long, chromate finish, flathead, thread forming screws supplied with the
panel. Use of any other hardware could cause contact with internal parts of the circuit breaker
panel. If parts are missing, please contact ADC.
