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. Although a higher SIL ensures a
higher level of safety, and a lower level of probability that a system will fail-dangerous, SIL 4 systems are
often too complex to implement and typically only apply if there is a risk of multiple casualties.
Additionally, if a process requires a SIL 4 system due to its high risk, the process design and/or
implementation should be re-examined/re-evaluated instead of relying on an instrument or a set of
instruments for safety.
Note: A similar approach to functional safety is the Performance Level (PL) rating system described in
ISO 13849. VeriSafe will only have a SIL rating (IEC 61508), not PL (ISO 13849). Top of the Document
FS03 Does the AVT maintain its SIL-3 rating over time?
Yes, the AVT maintains its SIL-3 capability over its rated life. An installed AVT does not have to be re-
tested for the SIL-3 maintain capability. The AVT does a self-check each time it is operated by a user
pushing the button should there be a failure. Top of the Document
FS04 Does VeriSafe have a Performance Level (PL) certification?
No, VeriSafe does not have a PL rating per ISO 13849. However, it does meet the requirements of SIL 3
per IEC 61508. Top of the Document
FS05 How can I access the IEC 61508 functional safety certificate?
Panduit’s Functional Safety documentation is public on Exida’s website, and the certificate and
assessment report can be accessed using the following link:

Indicator Battery
IB01 How long will the battery last?
The battery is designed to last for a minimum of 5 years under normal operating conditions. However,
temperature extremes and number of uses can impact battery life. If you push the test button and the
yellow Caution Indicator does not start flashing, you should replace the battery. Top of the Document
IB02 Where can a replacement battery for the indicator module be obtained?
The replacement battery can be obtained from an electrical or electronic products reseller. Refer to the
AVT Instruction Manual for a list of acceptable batteries. Standard AA batteries cannot be used in the
Indicator Module. Top of the Document
IB03 Do I have to de-energize my equipment to replace the battery?
The battery compartment is designed to be finger safe and completely isolated for electrical hazards.
The battery can be replaced in the Indicator Module without the need to de-energize and open the
equipment. Top of the Document
