Control Panel Installation
4.1 Mounting the 5820 Cabinet
Read the environmental specifications in Section 3.2 before mounting the 5820 cabinet. This
will ensure that you select a suitable location.
The panel should be accessible to main drop wiring runs. It should be mounted as close to the
center of the building as possible and located within a secured area, but should be accessible
for testing and service.
Mount the 5820 so it is firmly secured to the wall surface. When mounting on concrete,
especially when moisture is expected, attach a piece of 3/4-inch plywood to the concrete
surface and then attach the 5820 to the plywood. Also mount any other modules to the
plywood.
The 5820 cabinet can be surface- or flush-mounted. If you will be flush-mounting the cabinet,
the hole for the enclosure should be 14.75" W x 25" H x 4" D. Do NOT flush-mount in a wall
designated as a fire break.
4.1.1 Removing the 5820 Assembly from the Housing
If it should ever be necessary to remove the 5820 assembly from the cabinet for repair, do so
by unscrewing the nuts that connect the 5820 assembly to the cabinet. Do not attempt to
disassemble the circuit boards. See Section 3.5 for location of the nuts.
Caution!
To avoid the risk of electrical shock and damage to the unit, power should be OFF at the control panel while
installing or servicing.
