Key Features of the
VeriSafe AVT
Installed in the enclosure, the
VeriSafe AVT has the following
features:
• Tests without exposure to voltage
• Self-contained; no need for
additional meters, tools, or
voltage source
• Built-in pre-/post-verication test
• Tests phase-to-phase and phase-
to-ground for AC and DC voltage
• Automated test sequence
• Active indication for absence of
voltage
• Supports compliance with NFPA

the tester, during the test if the panel is not de-energized, and after the
test when re-verifying the hand-held tester. Because an enclosure must be
accessed while performing the voltage verication test with a hand-held
test instrument, there is potential for signicant risk of exposure to
electrical hazards.

Absence of Voltage Tester
The VeriSafe Absence of Voltage Tester (AVT) is the rst absence of voltage
tester listed to UL 1436
11
designed specically to verify the absence of
voltage in electrical enclosures.
The VeriSafe AVT reduces the risk of exposure and helps eliminate user
error. With a built-in self-test mechanism, there is no need to access a
separate known voltage source to verify that the tester is functioning.
Operating the AVT will not expose workers to electrical hazards.
Hand-held voltage testers possess certain limitations when used for
verifying the absence of voltage, such as worker misuse, mechanical and
electrical failure, inadequate application rating, inadequate or incomplete
worker training, and possible inadvertent exposure to electrical hazards
while verifying the absence of voltage.
In comparison, the VeriSafe AVT presents the following advantages over
hand-held voltage testers when verifying the absence of voltage:
• Allows the operator to test for absence of voltage without exposure
to electrical hazards, before removing doors and covers on
electrical equipment
• Automated test sequence reduces procedure time, complexity, and
human error
• Reduces errors due to inadequately rated testers and incorrect
tester settings
• Self-contained solution -- does not require additional tools, equipment,
or voltage source
• Less susceptible to damage than portable, hand-held equipment
• Provides a visual alert to abnormal power conditions by indicating when
voltage is present (red LEDs)
• Conrms absence of AC and DC voltage with a single test
