Installation Instructions

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).

• Sensor leads of the same color should be terminated on the same conductor. Each conductor should have at least one

sensor lead set, as shown on the schematic diagrams.

• Excess length from Sensor Leads should be trimmed; lead wires should not be extended with a splice.

• Always comply with local installation codes and standards.

• Always follow safety and lockout/tagout procedures when working on or near electrical systems and equipment.

• If a Sensor Lead separates from the termination point to the power conductor and contacts a low impedance path to

ground, the connectivity test can be defeated resulting in a false absence of voltage indication. Ensure that all sensor

leads are terminated properly and secured to the power conductor or other nearby rigid feature to prevent movement

if the termination fails to remain intact.

Before installation, verify that after power is removed from the circuit to be monitored, the potential measured between each line

and ground is less than 1.3 V.

1. Insert the Indicator Module in the

30mm knockout hole, align anti-

rotation notch. Ensure the rubber

washer is on the outside of the

enclosure.

2. Install the panel nut with the flange

towards the inside surface of the

enclosure.

3. Tighten the panel nut until both it and the

sealing washer make full contact with the

enclosure surface. Then, tighten an

additional ¼ turn. Tighten the panel nut

with fingers only, do not overtighten.

4. Snap the Isolation Module on the DIN rail. Alternately, the

Isolation Module can be mounted to any surface using three,

#8 pan head screws or another compatible fastener. Surface

mounting with screws is recommended for high-vibration

environments.

5. Insert the end of the AVT System Cable with the right-angle

connector in the back of the Indicator Module. Press firmly into

the opening until you feel it latch. Pull back on the connector to

verify that it has properly latched.
