REX®/REX2™ Meter Installation Instructions
General
This leaflet contains installation instructions for the REX and REX2-EA solid-state, residential
electricity meters (referred to as “REX” within this IL) with the following form factors:
■self-contained: Forms 1S, 2S, and 12S
■transformer-rated: Forms 3S and 4S
All meters are calibrated and sealed before shipment. For proper installation, accuracy, and
maximum life of the meters, use the following procedures.
WARNING
!
Use authorized utility procedures to install and service metering equipment. Dangerous
voltages are present. Equipment damage, personal injury, or death can result if safety
procedures are not followed.
WARNING
!
When using the REX meter with the internal service control switch, follow authorized utility
procedures to reconnect electrical service. Property damage, personal injury, or death can
result if proper safety precautions are not followed.
Installing the REX Meter
1. Make sure the meter to be installed matches the service type (that is, form), current,
capacity, voltage, and service socket.
2. Check the socket and verify that the wiring is correct. See “Internal Wiring Diagrams” on
page 2 and “Installation Wiring Diagrams” on page 3 for wiring diagrams.
3. Make sure that the voltage disconnect or test link on the back of the meter is closed, if
installed.
4. Line up the meter blades to the socket jaws and rock the meter into place. Make sure
that the meter is in the upright position.
5. Make sure the LCD turns on and the energy use indicator flashes if load is present.
The LCD has two pulse arrows. The arrow pointing to the left indicates energy received; the arrow
pointing to the right indicates energy delivered. For more information, see the technical manual for
your meter.
6. Apply all seals and record any necessary information.
