VeriSafe™ AVT Sensor Lead Connection Options

NOTE: See VeriSafe AVT Instruction Manual for complete Installation Instructions and Commissioning Checklist

1) Where to Install

The VeriSafe AVT is to be installed at the point in the circuit where you would normally test for voltage. If

there are more than one energy sources within the enclosure, multiple AVTs will be needed to test each

source (each AVT is designed to test one energy source from one to three phases).

2) General Information

The VeriSafe AVT is provided with 14 AWG Class K stranded sensor leads. Ferrules or terminals are

recommended for all sensor lead terminations to ensure reliable connections with stranded wire.

There are four sets of color-coded sensor leads (three conductors and ground). Each set of sensor leads has a

detection lead and a termination lead. The detection lead is used to detect voltage and the termination lead

is used to verify that the detection lead is in contact with a conductor. The termination lead does not detect

voltage. There are no labels distinguishing the detection and termination leads because it is critical that they

are both properly terminated.

Sensor leads for each phase and ground must not be mechanically terminated at the same point for the AVT

to function properly (see Figures 1 and 2). For example, if the termination shown in Figure 2 fails and the

sensor leads remain in contact with each other (yet no longer in contact with the conductor), the installation

test will be defeated for that set of sensor leads which may lead to inaccurate results from the AVT. If the

detection lead is not contacting a conductor, the result of the installation test will prevent the AVT from

returning a green absence of voltage indication.

terminated sensor leads. Leads are

not mechanically connected, and

termination points are insulated.

leads at the same point may result

in inaccurate AVT results.

There is no maximum distance limitation between the two leads on each phase, however there should not be

any circuit elements (ex. Circuit breaker, fuse, VFD, switch or similar control devices etc.) installed between

each pair of sensor leads. (see diagram below)
