WARNING
CRUSHING HAZARD
During meter installation or removal, always place the unit on a stable platform or surface
that supports its assembled weight.
Failure to comply could allow the meter to roll, resulting in serious injury or equipment
damage.
Procedure
1. Remove power to the meter.
2. If the installation has rigid conduit, use a medium size crescent wrench and loosen
the hex nuts on the Transmitter Electronics Enclosure. This should allow enough
slack to remove the Transmitter Electronics Enclosure from the Base Enclosure. If
the installation uses flexible conduit, you may not need to disconnect it from the
Transmitter Electronics Enclosure.
