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 Meter1. 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.
