Power injector
Due to the current draw requirements of each switch and
connected field devices like occupancy/photo sensors and
dimmable fluorescent and LED lighting equipped with
0–10 Vdc control circuitry, to operate correctly, a PRC Power
Injector (PRCDSNPI) may be required for proper operation.
The PRCDSNPI is required after each 15 PRCDS or when
the DSN length exceeds 500 feet. DSN connections to
the power injector are done in the exact same fashion as
each digital switch. The PRCDSNPI includes a separate dual
voltage 120/277 Vac power supply connection. Make sure to
connect to an unswitched branch circuit.
