The VeriSafe Absence of Voltage Tester is a permanently-mounted tester that is used to verify a circuit is de-
energized prior to opening an electrical enclosure. Once installed, a push of a button enables qualified electrical 
workers to verify the absence of voltage and see an active indication when the absence of voltage is confirmed. 
The Indicator Module is designed for a 30-mm notched panel knockout and the Isolation Module can be mounted 
to DIN rail or surface mounted using screws.
