A3 ALPHA® meter with
wireless cellular communication option
This leaflet provides general information for the Wireless WIC communication option for the A3 ALPHA meter. For information on installing the A3 ALPHA meter, see the “ALPHA Meter Installation Instructions” (IL42-4001Q or later).
The A3 ALPHA meter may be ordered with a wireless cellular communication option: the Wireless WAN Interface Card (Wireless WIC). The Wireless WIC is available in CDMA 1xRTT and GSM GPRS versions, providing a high speed cellular communication channel for the meter. Additional hardware configurations may include either a relay option board or an interrupter control board for standard ALPHA meters, or an EA_Gatekeeper module to communicate with the EnergyAxis LAN
The A3 ALPHA meter with Wireless WIC communication may be ordered in the following configurations:

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 secondaries are not used.

NOTICE

Location of antennas
See Figure 1 for the location of the Wireless WIC internal antenna. If the A3 ALPHA meter is serving as an EA_Gatekeeper, then the A3 ALPHA meter has two antennas: the Wireless WIC internal antenna is in the upper position and the EA_LAN internal antenna is in the lower position.
The Wireless WIC internal antenna and the EA_LAN antenna (if present) are fix-mounted to the periphery of the A3 ALPHA meter’s electronic housing. The Wireless WIC antenna and the EA_LAN antenna (if present) are not adjustable or removable.
Alternatively, A3 ALPHA meters may be ordered with an external WIC antenna. With this option, the meter is shipped with an RF “pigtail” output cable which allows connection to a dual-band cellular antenna external to the meter. This is advantageous in locations with lower cellular signal strength. Also, certain Wireless WIC configurations (for example, GSM GPRS) are presently only available with an external WIC antenna.
See Figure 2 for the recommended location of the Wireless WIC external antenna. Elster recommends mounting the external Wireless WIC cellular antenna on the top of the meter socket box as shown, centered in the available space on the meter box’s top surface.
Drill and/or punch the specified antenna mounting hole in the top of the meter socket box and install the antenna
using the antenna manufacturer’s instructions.
Connect the meter's RF “pigtail” output cable directly to the antenna via its integral N-type connector. The Wireless
WIC antenna output cable may be ordered in two lengths: 19 or 36 inches. Choose the length based on the distance from the meter to the Wireless WIC external antenna, which is in turn determined by the size of the meter socket box.
Please note that external cellular antennas must be purchased separately, either from Elster or a third party, from a list of approved antennas. Please ask your Elster Sales Representative for the current list of approved external cellular antennas.
Use approved utility safety procedures while installing the external antenna and meter RF output cable in the meter socket box. Dangerous voltages may be present. Assure that there is sufficient clearance between any line-energized socket part and the exposed metal of the antenna connectors. Also assure that the external antenna is electrically bonded to the meter socket box. Failing to follow approved utility safety procedures, failing to allow sufficient clearance, or failing to electrically bond the external antenna to the meter socket box may result in equipment damage, personal injury, or death.
