Load Wiring (Section B)
CAUTION: Bypass jumpers are provided on each output to allow testing and to protect the module during
installation. The jumper shorts the Land SW terminals so that the load circuit is energized when the branch breaker
is on. Do not remove the bypass jumper until all feed and load wiring has been completed, and the circuits have been
tested for electrical faults.
NOTE: Use copper conductors only – rated 75°C.

corresponding circuit breaker turned off, connect the controlled circuit (LOAD) wires to the output per the
markings on the module as shown in the following diagrams. Terminals for load wiring accept one 10 – 14
AWG wire.

The GLXP-DIMFLV8 also requires wiring the terminals for 0-10 VDC control wire. Refer to the following
diagram when connecting the dimmable ballast. Each control wire terminal accepts one 12 – 28 AWG wire.

2. Test the circuit for electrical faults by turning on each circuit breaker, checking that the breakers do not
trip, and that power is delivered to the proper loads.
3. Turn off the circuit breaker(s) and remove all jumpers.
4. Turn on the circuit breakers.
Control Wiring (Section C)
The bottom of the cabinet contains Cresnet®connections for interfacing to the rest of the Crestron®control system.
It also provides an override input which can be tied to devices such as the GLS-PLS-120/277 phase-loss sensor, or
other devices that provide a dry contact closure (manual switch, fire alarm relay, etc.).
NOTE: Interface connectors for NET (x2), POWER (x1), and OVERRIDE (x1) ports are provided.

NET Port Wiring
When wiring the supplied NET connectors for connection to a Crestron control system or other device on the
Cresnet network, use Crestron certified wire such as CRESNET-NP or CRESNET-P.
To ensure optimum performance over the full range of your installation topology, use Crestron certified wire.
Failure to do so may incur additional charges if support is required to identify performance deficiencies because
of using improper wire.
When daisy-chaining connections between NET ports, strip the ends of the wires carefully to avoid nicking the
conductors. Twist together the ends of the wires that share a pin on the network connector, insert the connection
into the Cresnet connector, and tighten the retaining screw. Repeat the procedure for the other three conductors.
POWER Port Wiring
Low voltage (24 VDC) power must be supplied to the modules either internally via devices connected to the
NET port or externally via a Cresnet power supply connected to the POWER port.
To power the modules internally from line power, install a jumper from the INT pin on the supplied POWER
connector to the EXT pin on the POWER connector as shown in the following diagram.
Providing Cresnet Power Internally
When a lighting module is powered from line power, the module’s PWR LED will illuminate.
Installation Guide – DOC. 6672B CRESTRON GREEN LIGHT Power Switching •9
Power Switching CRESTRON GREEN LIGHT™
To power the modules externally from a Cresnet 24 VDC power supply, connect the external power supply to
the EXT and Gpins on the POWER supplied connector as shown in the following diagram.

When properly connected and receiving 24 VDC power externally, the green LED next to the MODULES port
will light.
When a lighting module is powered from a Cresnet power supply in the absence of line power, the module’s
PWR LED will flash.
OVERRIDE Port Wiring
Low-voltage input devices such as the Crestron GLS-PLS-120/277 phase-loss sensor or any device that
provides a dry contact closure can be connected to the supplied OVERRIDE connector on the bottom of the
cabinet.
