Plug-In Voltage Presence Indicator

This device indicates voltage presence through a matched sensing or coupling circuit. The indicator and sensor must be compatible as a system. Review the input interface, wiring, indication thresholds, panel opening and any required auxiliary outputs. Define the indicator, coupling elements and connecting leads as separate supply items. Until its detection function and applicable requirements are established, absence of an indication must not be presented as proof of absence of voltage or a replacement for prescribed verification procedures.
