Preliminary

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
secondaries are not used.

Location of antennas

See Figure 1 for the location of the Wireless WIC antenna. If the A3 ALPHA meter is serving as an EA_Gatekeeper,
then the A3 ALPHA meter has 2 antennas: the Wireless WIC antenna is in the upper position and the EA_LAN antenna
is in the lower position.

The Wireless WIC 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.

Compliance Statement

This device complies with Part 15 of the FCC Rules and Class B digital apparatus requirements for ICES-003. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may
cause undesired operation of the device.

Note

This equ ipment has been tes ted and found to comply with th e limits for a Class B digital d evice, pursuant to Part 15 of the FCC Rules and ICES-003.
These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a par ticular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:

• reorient or relocate the receiving antenna

• increase the separation between the equipment and the receiver

• connect the equipment into an outlet on a circuit different from that to which the receiver is connected

operated in conjunction with any other antenna or transmitter except as documented in the FCC application. These devices have been approved for
simultaneous transmission of the collocated EA_LAN and cellular/PCS transmitters. Users and installers must be provided with antenna installation
instructions and transmitter operating conditions for satisfying RF exposure compliance.

Preliminary

Placing the A3 ALPHA meter with Wireless WIC into service

See IL42-4001Q or later for the A3 ALPHA meter installation instructions. When planning the meter installation,
consider the following additional guidelines:

■ Since the Wireless WIC and EA_LAN (if present) are high frequency communication devices, site the meter so

that the front of the meter has the best possible view of the surrounding terrain.

■ Do not place metal structures (other than the meter socket and related cabling) within 20 cm of the meter.

After the A3 ALPHA meter is installed and powered as instructed in IL42-4001Q or later, the installation is complete. If
on-site verification of the Wireless WIC operation is desired, the following steps may be taken:

To verify that the Wireless WIC is operational:

1. After installing and powering the A3 ALPHA meter, wait approximately 5 minutes for the Wireless WIC to
connect to the cellular network and initialize.

2. Using Metercat and an optical probe connection, perform a diagnostic read. For information on using
Metercat and performing diagnostic reads, see the Metercat software documentation or online Help.

3. Once the diagnostic read is performed, select the Special Option Board section. Several operational
parameters are provided, including the following:

Item Expected status

WAN Wireless Status

Status Connected means the Wireless WIC is registered

to the cellular network

Received Signal Strength
Indication (RSSI)

WAN IP address The IP address provided by the cellular network.

The RSSI may vary between 0 and 31, with 31
indicating the best possible signal strength. An
RSSI value of 99 indicates an unknown or non­detectable signal.
