The Safe Way to Protect Employees and Equipment
Panduit ’ s VeriSafe 2.0 AVT ( absence of voltage test ) system eliminates the risk of arc flash by confirming any electrical cabinet is de-energized before allowing access . The surface mounted module indicates when it is safe to access a panel , a green indicator is shown , and when it is unsafe to access a panel , by a red light indicator appears , prior to accessing the panel , eliminating risk to plant operators , machine builders and onsite engineers and electricians . The VeriSafe AVT system can be combined with a door interlock system so that the panel doors cannot be opened unless the test has been carried out and “ green light status ” achieved .
The traditional method for testing for presence of voltage is to , dress in correct PPE , turn off the panel , open the panel , verify the portable tester is operational , test the panel for voltage , re-verify the tester , then , if safe , perform necessary work within the cabinet . This process has two major setbacks . Firstly , this entire process can take around 10 minutes to perform and secondly , a number

VeriSafe AVT ensures the absence of voltage by using the following process :
• Turn off the panel
• Push the button on the VeriSafe Indicator Module , located on the outside of the panel
• When the green light indicates , open the panel , it is now safe .
This method has two of major benefits , the panel is not opened until after it is confirmed that the panel is de-energized , which eliminates risk and improves safety . The entire process takes approximately 10 seconds , compared to the traditional 10 minutes , and so increases productivity .
Moreover , the Verisafe AVT performs a number of complex tasks , which include , confirms power is available to perform the test , checks health of key circuit elements , verifies threshold circuits in tolerance , checks on known voltage source , verifies connectivity and verifies voltage is under 3V threshold .
As well as eliminating risk and improving productivity Panduit ’ s AVT meets various standards , its safety functions meet SIL 3 ( IEC 61508-1 ), as well as redundant channels for measurement and detection . The system also satisfies the criteria in NFPA 70E 120.5 ( 7 ) Exception 1 & CSA Z462 4.2.5 ( g ) Exception 2 , and UL 1436 listing .
VeriSafe 2.0 , automatically ensures that the entire test process is followed for every single test . With a push of a button , users can achieve tested safety in both 3-phase and single-phase applications in the extended voltage range up to 1000V for AC and DC applications .
