Questions and Answers General Product Information GP01 Will voltage be present on the door when VeriSafe is installed? Hazardous voltage is isolated from the VeriSafe Indicator Module and door. Hazardous three-phase voltage will not be present on the AVT System Cable or Indicator Module. There is non-hazardous (less than 5 V), just enough to power the LEDs on the indicator.
PAGE 8
GP08 Is the device protected from static electricity? The device is protected from static electricity. Top of the Document GP09 Is the VeriSafe Absence of Voltage Tester protected from power surges? The VeriSafe AVT circuit design includes features that will conduct a typical surge to ground to prevent damage to the device. In the case of a surge event that is extreme in voltage level or duration, there are resistors that will fail to an open state.

article 240.21(B)(1)(b) Exception (NFPA 70:2017). This rule allows a tap of no more than 10 feet on a feeder circuit without the need for overcurrent protection. Other local wiring codes and regulations may require use of overcurrent protection. Always follow applicable codes and standards when installing the device. The VeriSafe AVT can be installed safely with overcurrent protection.
PAGE 10
IS07 Can the AVT be installed to monitor the output of a Variable Frequency Drive (VFD)? The AVT is not intended to be used for monitoring the output voltage from a variable frequency drive, and we do not recommend it for this application. Top of the Document IS08 Can VeriSafe be retrofit into existing equipment? Will this void the UL listing? VeriSafe is suitable for greenfield and brownfield applications.

wire. However, the AVT will still detect voltage between phase and each phase and ground. Top of the Document IS15 Can VeriSafe be installed in systems utilizing parallel runs? Yes. Some applications may use multiple cables per phase. In these cases, it is recommended to install each sensor lead on a separate cable for redundancy. Top of the Document IS16 Can VeriSafe be installed in ungrounded systems? Yes.
PAGE 12
4 Proper installation of sensor leads could not be verified If the indicator flashes 3, 5, 6, or 7 times, contact Panduit Tech Support for additional troubleshooting. Top of the Document OP03 Is PPE required to initiate an absence of voltage test with the VeriSafe Absence of Voltage Tester? The VeriSafe Absence of Voltage Tester allows qualified personnel to test for absence of voltage by pressing a test button located outside of the enclosure where the tester is installed.
PAGE 13
OP07 How would an operator know if nominal voltage is detected? If the nominal voltage is detected, the Voltage Presence indicator(s) will be illuminated. These red LED's are for reference only. Lack of illuminated of the red LED's does not guarantee the absence of voltage. Top of the Document OP08 Are users protected from hazardous voltage when using the AVT? VeriSafe is designed with several layers of protection with regards to electrical isolation.
PAGE 14
OP13 What is the “known voltage source” used to verify that the VeriSafe Absence of Voltage Tester is operating satisfactorily? In the VeriSafe AVT, the known voltage is not the battery, however it is generated by the battery. The value of the generated voltage exceeds the absence of voltage threshold (3V), ensuring that the tester can detect an unsafe condition.
PAGE 15
SR04 Do the door mounted Indicator module and DIN mounted Isolation module have different operating temperature ranges? The Indicator module and Isolation module are considered together as a system for the temperature ratings. Top of the Document SR05 What is the withstand rating of the AVT? VeriSafe has a short circuit current rating of 300,000A at 600V. Top of the Document SR06 What is the impedance rating of the AVT? VeriSafe is designed with 1 Megaohm impedance.

mode of operation). This is equivalent to one hazardous failure in 10,000,000 hours or 1,000+ years of continual operation. Keep in mind that the VeriSafe Absence of Voltage Tester safety function is only operating for about 10 seconds and only when the button is pushed, so this is an extremely high level of reliability. UL 1436 requires SIL 3 for safety functions of absence of voltage testers.
PAGE 17
IB04 If the threshold is 3.0V, why do I have to verify that my de-energized line voltage is below 1.5V before installing? This is necessary because of the tolerance range for the threshold value. Accounting for that tolerance, if voltage is greater than 1.3V when a circuit is de-energized, there is a possibility that the green Absence of Voltage indicator will not illuminate. Top of the Document IB05 How many grams of Lithium does the VeriSafe AVT Indicator battery contain? Approximately 0.7 grams.
PAGE 18
IM02 What is the rating of the Isolation Module output contacts? The output contacts have the following specifications: • • • • • • • • • Two channel, single-pole, normally open solid state relay Relay closure upon absence of voltage verification 5000 Vrms Input/output Isolation Contacts rated for 30V AC/DC Load Current 80 mA AC rms / mA DC On-Resistance 30 Ω (max) Compatible with up to 16 AWG (1 mm2) SIL3 compliant Duty Cycle: 10 seconds per test cycle Load Current Peak: t=10ms, ±350mA Off-State leakag
PAGE 19
SL03 Can the AVT Sensor Leads be extended? The 10ft maximum lead length is necessary to comply with the AVT listing requirements in UL 1436 as well as the NEC tap rule [NEC 240.21 (B) (1) (b) Exception] to avoid using overcurrent protection. Do not extend the sensor leads with a splice. Use approved connection methods and follow local codes and standards when terminating the sensor leads.
PAGE 20
AVT System Cable AS01 What is the purpose of the AVT System Cable? The AVT System Cable connects the Isolation and Indicator Modules. This cable requires eight conductors to carry the battery voltage (used for test-the-tester), power and signals for the red, yellow and green LED’s and pushbutton signal to initiate the test. The design uses an RJ45 jack and Ethernet style cable to make this connection.
PAGE 21
AC05 Is the VS-ACK-BATTERY replaceable? The VS-ACK-BATTERY has screw terminals to enable easy and efficient user replacement. Once the battery dies, the user would need to access the panel, remove the old battery casing, and replace with another VS-ACK-BATTERY.
