INSTALLATION AND OPERATING INSTRUCTIONS
R-3D2 series Flex-Mount Voltage Indicators
Part Number Description:
The R-3D2 series Flex-Mount Voltage Indicator introduces a 90° angle display for
(Top, Right, Left or Bottom) mount thru either M20 or 3/4” size knockouts. (Hardware included)
General Usage:
This 3-phase device reduces the risk of electrical arc flash into a HazLoc area by pre-verifying the
electrical isolation from outside of a control panel. Engineered with redundant circuitry, the voltage indicator is
powered by the same voltage that it indicates. The voltage indicator package is externally mounted to one of four
sides of a power disconnect or a motor controller box. The 20mm threaded bushing protects 4 or 5 wires entering
into the box. For proper seal, use either M20 or 3/4”knockouts, follow respective assembly drawing page 4 & 5.
For 3/4” knockout sizes, a 20mm to 3/4” threaded adapter is included. Whenever AC or DC voltage is above detection
thresholds the display indicators will flash or glow.
UL APPROVED FOR: CLASS I, DIVISION 2 HAZ LOC CAT III & IV
