VeriSafe 2.0 AVT
Operating Instructions
WARNING:
To avoid electric shock, always de-energize power before entering an electrical enclosure .
Always follow safety and lockout/tagout procedures when working on or near electrical systems and equipment .
Use proper personal protective equipment (PPE) when working around sources of hazardous electrical energy .
The product must be installed and commissioned by a qualified electrical worker familiar with local and national electrical
codes .
The AVT will only test for absence of voltage at the point in the circuit where it is installed . If there are other sources of
power in the equipment, dangerous voltage may be present .
Lack of red voltage presence indicators alone does not verify the absence of voltage, the absence of voltage test must be
initiated followed by the illumination only of the green indicator to verify the absence of voltage .
The AVT should only be operated by individuals who have been trained on the operation of the tester and can demonstrate
knowledge of the following criteria:
Familiar with requirements and information in the Instruction Manual and understand the function of the AVT, meaning of
the indicators and markings, and limitations of the Voltage Presence Indicators .
Aware of where the AVT is installed in the electrical system and any additional electrical hazards that may be present in
the system that are not detectable by the AVT .
Able to recognize electrical hazards and familiar with lockout/tagout procedures .

rapidly to indicate test in process,
illuminates solid to indicate the test has failed and flashes after a solid il-
lumination to indicate the reason for failure, see Troubleshooting section
for additional information .
VOLTAGE PRESENCE INDICATORS:
The
red
indicators illuminate when the
presence of hazardous voltage is detected .
Lack of red voltage pres-
ence indicators alone does not verify the absence of voltage.
VOLTAGE PRESENCE INDICATORS
A . When voltage is detected in one or more phases, the
appropriate voltage presence indicators will illuminate .
B . Lack of red voltage presence indicators alone does not
verify the absence of voltage . To test for absence of
voltage, push the test button .
ABSENCE OF VOLTAGE TEST
Each time the test button is engaged, the absence of voltage test sequence will be activated . The test
sequence includes running a self-check, using a known voltage source to test-the-tester to verify that
the AVT is functioning, testing for AC and DC voltage phase-to-phase and phase-to-ground, and verify-
ing the sensor leads are in contact with circuit conductors .
1.
De-energize the circuit according to company safety procedures .
2.
Verify that lockout/tagout devices have been applied to all applicable energy sources and the volt-
age presence indicators are not illuminated .
3.
Press the test button to initiate the absence of voltage test .
4.
The caution indicator will begin to flash . This indicates that the test is in progress .
5.
When the absence of voltage is verified, the absence of voltage indicator will illuminate .
6.
If the absence of voltage is not verified, the caution indicator will illuminate for about five seconds
followed by a series of flashes . The number of flashes will help diagnose why the test failed . Refer
to the Troubleshooting section for additional information .
