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
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 mm
2
)) or 1.6 Ohms (Cresnet HP: 12 AWG (4
mm
2
)).
P = Cresnet power usage of entire run (or chain).
