3-20 | Thermox WDG-V / VC / VCM with Blow Back
• Follow all applicable electrical codes for your location.
• Follow proper grounding, shielding and noise protection practices as
described in this section.
• For all sensor and signal wiring use twisted-pair cable, 18 to 22 AWG
(0.82 mm
2
to 0.33 mm
2
), with an overall braided shield, or twisted-pair
cable in rigid metal conduit.
• For AC mains supply wiring, use between 12 and 14 American Wire
Gauge (AWG) or equivalent metric between 3.3 mm 2 and 2.1 mm2.
• Use the conduit entry point closest to the connections you are making.
Do not add any additional conduit entry holes!

WDG-V Mains Supply Connections
Do not run control unit AC mains supply wiring in the same conduit
with other AC line power wires. By keeping this wiring separated,
you prevent transient signals from reaching the control unit.
The WDG-V can operate using between 115 VAC, ± 10% or 230 VAC, ± 10%.
There is no power switch or circuit breaker on the sensor, and it must be
protected by installing it on a circuit-protected line, maximum 15 amperes,
with a switch or circuit breaker in close proximity to the control unit and
within easy reach of an operator. Mark the switch or circuit breaker as the
control unit disconnecting device.
