1.20 Protective Covers
The panel has three protective covers mounted on the rear side of the panel. Two of these are
snap-on covers that mount over the input power connectors. A third, larger cover mounts over
the output power connectors and the external alarm connections. This cover is secured with four
6-32 screws provided with the panel. Access to these connectors and terminals is obtained by
removing the appropriate cover. The covers over the input power terminals are removed by
unsnapping them from their position. The larger cover is removed by loosening (but not
removing) the four screws. The holes in the large cover are keyed to allow it to be pulled to the
side and lifted clear of the screws.
1.21 Mounting
The circuit breaker panel can be mounted in a 19- or 23-inch rack (48.26 or 58.42 cm) using the
mounting brackets shown in
Figure 2 on page 3 . The panel can be flush mounted or recessed 1,
2, 3, or 4 inches (25.4, 50.8, 76.2, or 101.6 mm) from the front of the rack. The mounting holes
are slotted to permit installation in racks with WECO 1.00-inch (2.54 cm) hole spacing or EIA
1.25-inch (3.18 cm) hole spacing.
The following mounting brackets and screws are enclosed with the circuit breaker panel:
• Two brackets for 19-inch rack installations;
• Two brackets for 23-inch rack installations;
• Eight 5/16-inch (7.936 mm) long, 8-32 chromate finish, thread-forming, flathead screws
for attaching the brackets to the circuit breaker panel;
• Four 3/8-inch (9.525 mm) long, 12-24 thread-forming screws and washers for attaching
the brackets to the rack.
The slotted mounting hole pattern in the mounting brackets compensates for vertical rack
differences and allows mounting the circuit breaker panel in either 1.75- or 2-inch (4.45 or 5.08 cm)
rack spaces.
Note: The panel requires one open rack space above the chassis and one open rack space
below the chassis for heat dissipation.
Caution: Use only the 5/16-inch (7.936 mm) long, chromate finish, flathead, thread forming
screws for attaching the mounting brackets to the circuit breaker panel. Use of any other
hardware could cause contact with internal parts of the panel. If parts are missing, please
contact ADC.
