As of the date of manufacture, the unit has been tested and found to comply with
specifications for CE marking.
NOTE: This unit complies with part 15 of the FCC rules. Operation is subject to the
following two conditions: (1) these devices may not cause harmful interference, and
(2) these devices must accept any interference received, including interference that
may cause undesired operation.
Setup
Network Wiring
NOTE: This section only applies to those applications using 4-wire Cresnet wiring.
When calculating the wire gauge for a particular network run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If network units are to be daisy-chained on the run, the power factor
of each network unit to be daisy-chained must be added together to determine the
power factor of the entire chain. The length of the run in feet and the power factor of
the run should be used in the following resistance equation to calculate the value on
the right side of the equation.
Resistance Equation
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
R < L x PF
40,000
Where:
The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the table after this paragraph.
