Terminal Block & Module
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.
Terminal Block Installation and Field
Wiring
1. Use the two supplied self-tapping pan Phillips
screws (8B x ¼ length) to secure the terminal
block and the appropriate (left or right) wiring
label to the Crestron Automation Enclosure. The
wiring label lies beneath the terminal block as
shown in the two wiring diagrams on this page.
NOTE: Both left and right wiring labels are
provided. The left-side labels are common for both
single and double-wide enclosures. The right-side
labels are only used in double-wide enclosures since
the modules and terminal blocks along the right side
must be inverted when mounting.
CAUTION: Bypass jumpers are provided to allow
testing of circuits and to protect the module during its
installation. When properly secured by five screws,
the jumper on the black and red section of the
terminal block shorts the hot to dim (1 – 4) so that all
circuits are energized. Furthermore, the jumper on the
white section of the terminal block ties all neutrals
together. Do not remove any bypass jumpers until all
feed and load wiring has been completed, the circuit
has been tested for electrical faults, and the module
has been installed. Refer to "Module Installation" on
next page.
NOTE: Use copper conductors only – rated 75°C
2. With the circuit breaker turned off, connect the
circuit feed (HOT and NEUTRAL) and
controlled circuit (LOAD) wires to the terminal
block per the markings provided on the wiring
label (as shown in the diagrams on this page).
Terminal blocks accept one 14 - 10 AWG wire.
Wires should be stripped to ½ inch. Tighten
terminal blocks to 9 in-lbs. Do not over tighten.
3. Grounding terminal blocks are available in the
cabinet for termination of ground wires. Tighten
to 35 in-lbs. (14 – 10 AWG), 40 in-lbs.
(8 AWG), or 45 in-lbs. (6 – 4 AWG).
4. Test the circuit for electrical faults by turning on
the circuit breaker and checking that the breaker

does not trip and that the proper lights are
energized.
