4.3 24VAC Power Input and Internal Wiring
The NWVS internal power supply is half wave rectified. The command input
and analog outputs share a common ground with the 24VAC power input
ground. The diagram below details the internal wiring of the NWVS.
WARNING: EXCEEDING 30MA OR 15V ON THE COMMAND INPUT
CAN PERMANENTLY DAMAGE THE NWVS CAUSING THE OUTPUTS TO STAY ON
100%. USE CARE WHEN WIRING THE COMMAND INPUT AND USE A SEPARATE
(REDUNDANT) OVER TEMPERATURE SHUTDOWN DEVICE TO SWITCH POWER OFF
IF SAFE TEMPERATURES ARE EXCEEDED.
