Installation
WARNING: To avoid re, shock, or death, turn off the power at the circuit breaker(s) or
fuse and test that power is off before wiring!
NOTE: Observe the following points:
• This product must be installed and used in accordance with the appropriate
electrical codes and regulations.
• This product must be installed by a licensed electrician.
• Use 75°C copper wire or better.
NOTE: Before using the GL-EXP-*-CN, ensure the device is using the latest rmware.
Check for the latest rmware for the GL-EXP-*-CN at www.crestron.com/rmware. Load
the rmware onto the device using Crestron Toolbox™ software.
Preparing and Connecting Cresnet, 0-10V, and Override Ports
Strip the ends of the wires approximately 7/16 in (11 mm). Use care to avoid nicking the
conductors. Tighten the connector to 5 in-lb (0.5 to 0.6 N-m). The wire gauge should be
14 to 26 AWG.
Installation
Mount the GL-EXP-*-CN to any vertical surface using four screws. The screws must be
appropriate for the mounting surface.

NOTE: To prevent potential heat damage to the drywall, do not mount the
GL-EXP-*-CN directly onto drywall. Mount the GL-EXP-*-CN to a piece of plywood that
is at least 1/2 in (13 mm) thick, and then mount the GL-EXP-*-CN and plywood to the
drywall.
NOTE: To ensure proper ventilation, the device must be installed vertically on a vertical
surface. Install the device with 6 in (153 mm) of clearance from the top and bottom of
the device.
