Module Installation
NOTE:
Before the two-position bypass jumpers,
shown in the illustration, are removed, the Crestron
Professional Automation Computer (PAC2), which
provides control to the system, should be properly
connected and contain a valid program to provide
control of the module.
CAUTION:
Module contains electrostatic sensitive
devices (ESDs); unit must be handled from metal
chassis – do not touch PC board or components.
NOTE:
Modules are to be installed after enclosure
has been completely wired. Refer to the terminal
block installation procedure on page 2 for details.

1. Use the four supplied self-tapping pan Phillips
screws (8B x ¼-inch (6 mm) length) to secure
the module to the enclosure.
2. As shown in the wiring diagrams (next column),
connect the wires from the module to the
terminal block. Each wire exits the module
directly in line with, and is the same color as, the
terminal to which it should be connected. Wires
are pre-stripped to 12 mm. Tighten to 1 Nm. Do
not over tighten.
3. If the module is being installed above another
module within the enclosure, attach the supplied
module interconnect cable between the two
modules. The illustration below depicts the area
within a double-wide enclosure where the
corners of four modules meet.
NOTE:
One wire on the module interconnect cable
may be a different color from the rest. The color has
no bearing on its orientation during installation.

4. Turn on the circuit breaker and verify that the
green
PWR
LED on the module lights, the
breaker does not trip, and power is delivered to
the loads.
5. Turn off the circuit breaker and remove the two-
position bypass jumpers on the brown and red
sections of the terminal block. The jumpers on
the blue sections of the terminal block remain
installed. Refer to the figures in the next column
for a close-up of the jumpers.
