A3 ALPHA
®
meter with
wireless cellular communication option
General
The A3 ALPHA meter may be ordered with a wireless cellular communication option: the Wireless WAN Interface Card.
The Wireless WIC is available in CDMA 1xRTT and GSM GPRS versions, providing a high speed cellular
communication channel.
This leaflet provides general information for the Wireless WIC that is installed within an A3 ALPHA meter.
■ For information on installing the A3 ALPHA meter, see the “ALPHA Meter Installation Instructions” (IL42-
4001Q or later)
Use authorized utility procedures to install and service metering equipment. Dangerous voltages are present.
Equipment damage, personal injury, or death can result if safety precautions are not followed.
Use circuit closing devices on current transformer secondaries (3S, 4S, 5S, 5A, 6S, 6A, 8S, 9S, 10S, 10A, 26S,
29S, 35S, 36S, and 36A meters). Equipment damage, personal injury, or death can result if circuit closing
