Installation Instructions
Special
Conditions
of Use
Hazardous Locations
The equipment shall be installed in an enclosure that provides a degree of protection not less than IP 54 in accor-
dance with IEC 60079-0 .
The enclosure must only be accessible with use of a tool .
WARNING:
The AVT must be installed correctly and grounded as described in this Instruction Manual to provide proper indi-
cation 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 .
Sensor leads of the same label designation should be terminated on the same conductor (L1, L2, L3, GND) . 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 . When using
terminal or power distribution blocks, the total length of the sensor leads from the isolation module to the source
conductors shall not exceed 10 feet (3 .0m) .
Always comply with local installation codes and standards .
Always follow safety and lockout/tagout procedures when working on or near electrical systems and equipment .
NOTE:
Before installation, verify that after power is removed from the circuit to be monitored . The potential measured
between each line and ground should be less than 2 .7V, including voltages on the line from auxiliary systems
.
ISOLATION MODULE
NETWORK MODULE
DIN-RAIL MOUNTING
Snap the Isolation Module
onto the DIN rail .
OR SURFACE MOUNTING
Mount the isolation module
to any surface using four
#6 [M3 .5] pan head
screws or another
compatible fastener .
Surface mounting with
screws is recommended
for high vibration
environments
ATTACHING NETWORK MODULE TO ISOLATION
MODULE (OPTIONAL)
If mounting
to isolation
module,
use screws
provided
with
network
module .
SENSOR LEAD TERMINATION
1.
Route the sensor and ground leads .
The sensor leads should not be any longer than necessary and should be routed to avoid sharp edges, pinch points or mechan-
ical damage .
There is no maximum distance limitation between the two leads on each phase, however there should not be any circuit ele-
ments installed between them .
Sensor leads should not be extended with a splice . When using terminal or power distribution blocks, the total length of the
sensor leads from the isolation module to the source conductors shall not exceed 10 feet (3 .0m) .
2.
Terminate the sensor and ground leads .
Use of ferrules or terminals is recommended .
Sensor leads for each phase and ground must not be mechanically terminated at the same point for the AVT to function proper-
ly .
Sensor leads of the same label designation should be terminated on the same conductor (L1, L2, L3, GND) . Each conductor
should have at least one sensor lead set, as shown on the schematic diagrams .
Secure the sensor leads to the conductors and insulate the connections .
AUXILIARY DC POWER (OPTIONAL)
If using DC power, connect the 12 or 24 VDC power source, see DC Power Input (page 4) .
The DC Power Input is marked for polarity;
connect the positive output of the supply to the terminal marked (+) and the negative output of the supply to the terminal marked (-) .
