Automation Enclosures
Installation
The enclosure must be mounted by a licensed electrician
in accordance with all national and local codes. Refer to
table on first page for the weight of a fully loaded
enclosure.
When choosing components to place in the enclosure,
refer to the table on page 1 to ensure that the maximum
weight capacity is not exceeded. Each module's product
page on the Crestron website lists the module's weight.
CLT Terminal blocks must be mounted using the column
of screw holes shown in the "Mounting Detail" diagrams.
CAUTION: These enclosures house equipment that
needs to be air-cooled. Therefore, mount in a well-
ventilated area. The ambient temperature range should be
32°F to 104°F (0°C to 40°C). The relative humidity
should range from 0% to 90% (non-condensing).
Furthermore, allow adequate clearance in front of the
vented cover for servicing and ventilation.
NOTE: Unless otherwise indicated, the lighting system
specified in this guide is modular, requiring assembly in
the field by a licensed electrician, in accordance with all
national and local codes.
If you require a UL Listed panel, Crestron offers this
service through its UL Listed panel shop. This includes
complete in factory system configuration and assembly by
Crestron for an additional fee.
NOTE: Install modules into the lowest available spaces
and continue toward the top of the enclosure.
NOTE: Enclosures are intended for indoor use only.
NOTE: When flush mounting, 5/8" drywall is preferred.
Wiring
CAUTION: All power feeds must be protected by 15 or
20 amp circuit breakers (supplied by others).
NOTE: Use copper conductors only – rated 60°C
NOTE: All wiring must be installed in accordance with
all local and national electrical codes.
NOTE: Two snap bushings are supplied. If required,
insert into knockouts at the bottom of the enclosure to
prevent damage to low voltage wiring.
Class 1 and Class 2 field wires must be kept separate.
Refer to the following illustrations showing single-wide
and double-wide wiring details. Areas for high voltage
(Class 1) wiring are shown along the top and side(s) of
