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. Top of the Document
SR07 Does VeriSafe meet the requirements for OSHA 1910.147 LOTO?
Yes, VeriSafe is considered a test instrument and the absence of voltage indicator (green light) could be
considered sufficient to verify that ELECTRICAL energy has been isolated/dissipated. However, that
alone does not guarantee that other energy sources are de-energized. Top of the Document
SR08 What is the Performance Level (PL) rating of VeriSafe?
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
SR09 Does VeriSafe have an officially published SCCR?
Yes, the SCCR is 300,000 RMS Symmetrical Amperes, 600 V Maximum. Top of the Document
SR10 Should the VeriSafe AVT be de-rated at higher altitudes?
The VeriSafe AVT is certified for use by UL at altitudes up to 5000 m (16,404 feet) above sea level. At
higher altitudes, the transient surge withstand voltage rating may be slightly reduced from the rated
value of 6KV. However, the insulating capacity of the AVT should not be affected. Top of the Document
Functional Safety
FS01 What is Functional Safety?
Functional safety is a methodology described in IEC 61508 to ensure that electrical, electronic, or
programmable electronic systems (E/E/PE) are designed in such a way to prevent dangerous failures and
to control them if they arise. Functional safety certification requires quantitative and qualitative
analysis by an ANSI accredited certification body that includes rigorous testing of the product and audits
of the manufacturer’s processes. Functional safety is measured by Safety Integrity Levels or SILs. The SIL
demonstrates the safety and reliability of the parts of the product that impact the safety functions,
particularly with regards to hardware and firmware. SIL levels in IEC 61508 are designated as SIL 1, 2, 3,
or 4 with 4 having the most stringent requirements. VeriSafe is designed for SIL 3 environments.

FS02 What does SIL 3 mean?
A safety integrity level, or SIL, is a way to measure functional safety. SIL 3 means that the average
frequency of a dangerous failure of the safety function is ≥ 10-8 to < 10- 7 (high demand or continuous
