VeriSafe 2.0 AVT
Schematics
WARNING:
The AVT must be installed correctly and grounded as described in this Instruction Manual to provide proper indication of
absence of voltage . Sensor leads must not be mechanically connected with each other for the device to verify connection
to the circuit . Correct function of the device must be verified after installation, see Commissioning Checklist section, p . 14 .
Failure to comply with these instructions could result in product failure, injury or death .
Sensor leads of the same labeled set (i .e .; L1, L2, L3 and GND) should be terminated on the same conductor . Each
conductor should have at least one sensor lead set, as shown on the schematic diagrams .
