Overview
The Crestron GL-IPAC-SW8 switching panel provides internal controls for eight circuits of
switched load and is expandable to support up to 64 circuits of switched load by adding external
panels and switching modules. It features local inputs for sensors and keypads, along with an
LCD user interface where installers or users can set up the system without having to connect to
a computer.
The GL-IPAC-SW8 is perfect for smaller-sized installations, such as retail stores, small office
spaces, parking garages, and service stations, which typically require only on/off switching—
eliminating the need for a larger, more expensive panel. In addition, the GL-IPAC-SW8 can be
easily integrated with Crestron automation solutions for centralized monitoring and remote
control of multiple locations.
Features
Out of the Box Lighting Controls
The GL-IPAC-SW8 comes preconfigured for use as the central control processor for a Crestron
Green Light® Power Switching system. Right out of the box, the GL-IPAC-SW8 affords easy
setup and programming for a complete switching system consisting of up to 64 switched loads,
16 local and two remote keypads, 24 occupancy and photo sensors, and 100 time clock events.
Keypads with as many as 12 buttons each can be programmed easily to control lighting loads
and other functions. Lights can be programmed to turn on and off automatically using the built-
in astronomical time clock. Lighting events may be programmed to occur at specific times or at
an offset from sunrise or sunset. Occupancy sensors and photo sensors may also be
implemented to enable automatic on/off lighting control based on room occupancy and ambient
light levels.
Save Energy
Built-in support for occupancy and photo sensors helps to strike a perfect balance between
daylight harvesting and comfort, reducing energy costs. Automatically turn off lights in
unoccupied areas to allow natural light level in the space to light the area. Crestron GLS sensors
can be placed strategically in each space to maximize the benefits of energy management.
Easy Deployment
Packaged in one metal enclosure, the GL-IPAC-SW8 can be deployed in small spaces, including
plenum ceilings. The surface-mount GL-IPAC-SW8 can be affixed to a wall or ceiling rafter,
cleanly out of sight. Standard wire-entry knockouts are provided.

Adding Additional Power
The following illustration indicates how to wire an additional power supply.
Wiring Guidelines
To ensure optimum performance over the full range of the installation topology, use Crestron
Certified Wire only. Failure to do so may incur additional charges if support is required to identify
performance deficiencies because of using improper wire.
Calculate Power
CAUTION:Use only Crestron power supplies for Crestron equipment. Failure to do so could
cause equipment damage or void the Crestron warranty.
Provide sufficient power to the system. Insufficient power can lead to unpredictable results
or damage to the equipment. Use the Crestron Power Calculator to help calculate how much
power is needed for the system.
When calculating the length of wire for a particular Cresnet run, the wire gauge and the Cresnet
power usage of each network unit to be connected must be taken into consideration. Use
Crestron Certified Wire only. If Cresnet units are to be daisy chained on the run, the Cresnet
power usage of each network unit to be daisy chained must be added together to determine the
Cresnet power usage of the entire chain. If the unit is run from Crestron system power supply
network port, the Crestnet power usage of that unit is the Cresnet power usage of the entire
run. The wire gauge and the Cresnet power usage of the run should be used in the following
equation to calculate the cable length value on the equation's left side.
L < 40,000 / R x P
L = Length of run (or chain)in feet.
R= 6 Ohms (Crestron Certified Wire:18 AWG (0.75 mm2)) or 1.6 Ohms (Cresnet HP:12 AWG (4
mm2)).
P= Cresnet power usage of entire run (or chain).

Product Manual — Doc. 7389C GL-IPAC-SW8 • 20
Make sure the cable length value is less than the value calculated on the right side of the
equation. For example, a Cresnet run using 18 AWGCrestron Certified Wire and drawing 20
watts should not have a length of run more than 333 feet (101 meters). If Cresnet HPis used for
the same run, its length could extend to 1250 feet (381 meters).
NOTE:All Crestron certified Cresnet wiring must consist of two twisted pairs. One twister
pair is the 24 and G pair and the other twisted pair is the Y and Z pair.
Strip and Tin Wire
When daisy chaining Cresnet units, 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 and
tin the twisted connection. Apply solder only to the ends of the twisted wires. Avoid tinning too
far up the wires or the end becomes brittle. Insert the tinned connection into the Cresnet
connector and tighten the retaining screw. Repeat the procedure for the other three conductors.
Add Hubs
Use of a Cresnet Hub/Repeater (CNXHUB) is advised whenever the number of Cresnet devices
on a network exceeds 20 or when the combined total length of Cresnet cable exceeds 3000 feet
(914 meters).
