▶ Voltage indicators are Permanent Electrical Safety Devices (PESDs) that visually represent

presence of voltage with ashing or non-ashing redundant LED lights.

▶ Typically hardwired to the load side of a disconnect switch on a MCC bucket or a variable

frequency drive, voltage indicators illuminate whenever hazardous voltage or stored energy is

present in the system.

▶ R-3W Series voltage indicators are a one-size-ts-all solution that detect 3-phase AC/DC

voltage for both AC and DC applications from 40-600VAC and 30-1000VDC, respectively.

▶ Safely and productively visualizes energy presence and enhances compliance to OSHA &

NFPA 70E/CSAZ462 when installed and veried by a qualied electrician and incorporated into

the facility’s electrical safety procedure.

® OPERATION GracePESDs® voltage indicators are self powered, UL listed, and permanently installed devices that visually represent presence of voltage with flashing or non-flashing, redundant LED lights. Typically hardwired to the load side of an electrical feeder or a disconnect switch, voltage indicators illuminate whenever hazardous voltage is present in any individual phase.

COMBINATION UNITS Grace PESD® Combination Units take our voltage indicator and voltage portal PESDs and couple them together with our custom labels. With our voltage indicator and portal connected to the same source, a task qualified worker or a qualified electrician can perform both presence and absence of voltage tests by using either a Non-Contact Voltage Detector (NCVD) pen or an adequately rated portable test instrument.

R-1V SERIES MEDIUM VOLTAGE INDICATOR Medium Voltage (MV) Indicators assist the qualified personnel to visually indicate presence of voltage inside a MV cabinet. The indicator directly bolts onto the main busbar using a ½” ring style connector and uses capacitive coupling between the device and ground for completing the flashing circuit without a hardwired connection.

FREQUENTLY ASKED QUESTIONS Q: How do I know if the voltage indicator is working? A: Once the voltage indicator is installed and verified by a qualified electrician and documented in the drawings and Q: Why are the GND LEDs “ON” in my delta connected system with isolated ground? A: On a balanced 3 Phase, Delta Configuration, the GND light safety procedures, a task qualified person can identify the will be off.
