Module Installation
In accordance with all national and local codes a licensed
electrician, , must mount the terminal blocks and modules
in field-assembled Crestron Automation Enclosures.
Terminal blocks are installed along the left side of single-
wide enclosures and along the outside edges (left and
right sides) of doublewide enclosures. Modules are
installed along the right side of singlewide enclosures and
side-by-side in the center of doublewide enclosures.
Refer to the illustrations when considering the location
of terminal blocks and modules within an enclosure.
CAUTIONS: This equipment is for indoor use only and
requires air cooling. Mount in a well-ventilated area.
The ambient temperature must be 32°F to 104°F
(0°C to 40°C). The relative humidity must be 0% to 90%
(non-condensing).
Modules contains electrostatic sensitive devices (ESDs)
and units must be handled from metal chassis – do not
touch PC board or components.
NOTES: Modules and terminal blocks must be installed
into the lowest available spaces and continue toward the
top of the enclosure.
Modules are installed after the enclosure has been
completely wired.
Single Width Enclosure Mounting
Module and associated terminal block installed in single
width enclosure are shown below. The PAC2 processor
occupies the lowest module position
Double Width Enclosure Mounting
Module and associated terminal block installed in double width
enclosure are shown below. The PAC2 processor occupies the
lowest module position.
Terminal Rail Bypass Jumpers
CAUTION: A bypass jumper is provided on the terminal rail to allow testing and to protect the module during installation.
When properly secured by nine screws, the jumper on the black and red section of the terminal block shorts the LINE in to
DIM out so that the circuit is energized. Do not remove the bypass jumper until all feed and load wiring has been completed,
the circuit has been tested for electrical faults, and the module has been installed. Furthermore, the jumper on the white
section of the terminal block ties the neutral in to the neutral outs. This jumper should never be removed.
NOTE: Use copper conductors only – rated 75°C.
