Permanent Electrical Safety Devices (PESDs) Permanent Electrical Safety Devices (PESDs) are defined as external devices (except Medium Voltage Indicators, which are internal) permanently mounted to electrical systems that, directly or indirectly, reduce the risk of arc flash and/or shock hazard. They provide feedback on the voltage state within the enclosure and eliminate proximate exposure to that same voltage. Some examples of PESDs include voltage portals and voltage indicators. Voltage Indicators: Flashing or non-flashing device that monitors both AC and DC voltage. They are externally mounted and give a visual indication outside the panel to the presence or absence of voltage. Voltage indicators Part Number: R-3W / R-3W-SR are available in Class 1 Div 2, solid-on LEDs, Fiber Optic, and medium voltage from 2KV to 43KV. R-3W, R-3W2, R-3W-SR, R-3F, Part numbers include: R-1VH003 and R-1VL003 Voltage Portals: Non-conductive, encapsulated point that allows for the detection of the presence or absence of voltage through a panel door with a non-contact voltage detector (NCVD). Part numbers include: R-1A003-LPH and R-T3 Part Number: R-T3W-LCH We use Permanent Electrical Safety Devices...to provide the operator tools to perform tasks outside of the enclosure rather than interacting with energized components. - Dennis Doody, Project Manager, Vitler PESDs and NFPA 70E The NFPA 70E states that the following principles are foundational to ensuring a zero energy state: 1 Locate all sources of electrical energy. Voltage portals and voltage indicators installed will locate each source. 2 Physically contact voltage detector to the electrical energy. Voltage indicators are hardwired to the source. 3 Test between each phase and phase to ground. Voltage indicators check voltage between phase-phase-ground. 4 Verify voltage detector before and after use. A non-contact voltage detector (NCVD) can be verified before and after use. Please note: Employers are responsible to train employees in selecting and properly using a voltage detector. It is also the 5 responsibility of employers to provide a written lock-out/tag-out procedure and train employees on those procedures. Follow manufacturers instructions when using a non-contact voltage detector. All other safety procedures apply.

(800) 280-9517 Fax: (563) 386-9639 www.pesd.comMore on Voltage Indicators SafeSide voltage indicators help keep workers safe during lock-out/tag-out by giving them valuable information about the state of voltage within the panel. Here are some key benefits and features about voltage indicators: Reduced Voltage Exposure and Arc Flash Risk - While performing electrical LOTO with a SafeSide voltage indicator installed, the electrician can pre-check the internal voltage state without opening the enclosure. Safer Lock-Out Tag-Out (LOTO) - Keeping personnel away from live voltage is foundational to electrical safety. Electrical safety demands a precise answer to the question Is voltage present . SafeSide voltage indicators provide visibility of voltage from outside the enclosure without exposing personnel to voltage. More Productivity in Mechanical LOTO - Workers performing mechanical LOTO must isolate electrical Part Number: R-3W / R-3W-SR energy. Without a SafeSide voltage indicator, a mechanic performing mechanical LOTO would be required to work in tandem with an electrician using a voltmeter to physically verify voltage inside an electrical panel. In this case, the electrician is exposed to voltage, but with SafeSide voltage indicator, the mechanic can verify zero electrical energy without any exposure to voltage.

Global electrical designs specify panel-mount devices that operate at low voltage levels the R-3F provides voltage indication with zero voltage on the outside of the panel. The R-3F uses an optical cable bundle to illuminate the LEDs on a thru-panel adaptor mounted to the outside of an electrical enclosure. The optical cable bundle allows users to see the voltage status of L1, L2, L3 and GRD with the energized conductors safely kept away from the enclosure exterior. The potted R-3F LED base unit with integral lead wires and flexible mounting options allow users to reliably locate it close to 3-phase voltage sources. The availability of different cable lengths lets users Part Number: R-3F with label (label sold separately) mount the fiber optic thru-panel adaptor at the best location on the enclosure.
