CHAPTER 1
INSTALLATION
This chapter provides installation requirements and instructions. It also describes the safety
warnings and precautions to use when installing or servicing the Residential Electric ANSI
Meters.
Warning: Make sure you read the following safety warnings and precautions before you
proceed with configuring, installing, and operating the meters.
Safety Warnings
Before you install and operate your meters, it is important to be familiar with all the safety
precautions. Observe these precautions during all phases of operation, service, and repair. Failure
to comply with these precautions or with specific warnings elsewhere in this guide violates safety
standards of design manufacture and the intended use of the meter. Metering Technology
Corporation (MTC) assumes no liability for your failure to comply with these requirements.
The information presented in this guide is intended to be an aid to qualified metering personnel.
It does not replace the extensive training necessary to handle metering equipment in a safe
manner.
Warning: Any work on or near energized meters or other metering equipment presents the
danger of electrical shock. Only qualified electricians and metering specialists are
authorized to work on the meters in accordance with local utility safety practices, utility
requirements, and other safety precautions as dictated by local code, regulations, or statutes.
Precautions
The meter is connected directly to line voltage. Observe all safety warnings as indicated on the
meter. Be sure to follow these precautions:
• Never service the meter alone.
• Be extremely cautious when working around exposed meter socket terminals.

Installing the Meter
This section describes the installation requirements and procedure to install the meter. Before you
proceed with the installation, make sure you have read the safety warnings and precautions on
page 5.
Preparing the Meters for Installation
Unpack the meters and perform the following steps.
To prepare the meters for installation:
1. Carefully inspect the meter case and terminals to make sure they were not damaged
during shipping.
Warning: Return damaged meters and components to MTC; do not attempt to repair the
damage. The meter has no user-serviceable parts. Any attempt to remove or repair internal
parts voids the meter warranty.
2. Do one of the following:
• To configure the meters in-house before you install them in the field, refer to the
manufacturer ’s host programming documentation.
• If you’re planning to install the meters in the field and then configure them remotely,
follow the instructions in this chapter to install the meters, then refer to the
manufacturer ’s host programming documentation for remote configuration.
Installing the Meter
The Residential Electric ANSI Meter must be installed by qualified persons. Check with local
regulations before installation. If you are unsure about installation issues regarding licensing or
local regulations, contact your local electrical utility.
Warning: Dangerous voltages exist in and at the meter socket terminals. Read all warning
and application information provided with the meters and sockets.
To install the meter:
1. Plug the meter into an ANSI approved socket with the label in the upright, or readable
orientation.
2. Install a sealing ring and seal.
Note: The internal wiring configuration of the Residential Electric ANSI Meter
complies with the Form 2S regulation standard.

• Each item in the list is displayed for 5 seconds. The display refresh rate is 1 Hz.
• The power usage indicator is the 'RUN' segment located in the upper left corner of the
LCD. With every 7.2 Wh consumed, the segment alternates its state from on to off.
• The threshold for the 'NO LOAD' segment is 0.075 A. The threshold for the energy
accumulation is 0.005 Wh which corresponds to 0.075 A at the nominal 240 V.
• The last 7 digits of the 10-digit serial number should consist of ASCII digits, since ASCII
letters are not properly displayed on the LCD. The first 3 digits of the serial number can be
letters since these are not displayed on the LCD.
• * The display is configurable as to which items are displayed. If no items are selected, the
entire list will be scrolled. This helps to indicate that the meter is running.

CHAPTER 3
OPERATION NOTES
This chapter provides miscellaneous notes regarding the operation of the Residential Electric
ANSI Meter. Refer to manufacturer ’s documentation for additional information.
Registered Quantities
To provide for the registration of both delivered and received kWh, there are 6 active energy
accumulators (including the 4 tariff accumulators). The Host must be able to request up to 6 active
accumulators, the order upon return is:
• KWh delivered
• KWh received
• Tariff 1 net kWh
• Tariff 2 net kWh
• Tariff 3 net kWh
• Tariff 4 net kWh
The registered value for reactive energy (kVARh) is the sum of all four reactive quadrants. This
meter cannot distinguish lead/lag. There are 5 reactive accumulators:
• Net kVAR
• Tariff 1 net kVAR
• Tariff 2 net kVAR
• Tariff 3 net kVAR
• Tariff 4 net kVAR
Load Profile
There are 9 items that can be selected for logging in the load profile log. These are:
• Net active power
• Active energy delivered
• Active energy received
• Instantaneous voltage
• Instantaneous frequency
• Active demand
I n s t a ll a t io n a nd U s e r’ s G ui de 9
C h ap t e r 3 O p e r at io n N ot e s
• Net reactive power
• Net reactive energy
• Power factor
The default setting is for 15-minute intervals, with the following 3 items logged:
• Active energy delivered
• Reactive energy delivered
• Voltage
Payment Meter Mode
When optionally configured for such use, the meter functions as a prepay meter. In this mode, the
meter continuously deducts the appropriate amount for energy usage from a dollar balance stored
in the meter. When exhausted beyond a configurable grace-period amount, the meter is
configurable to disconnect the load. For prepay operation, the meter must have the optional
disconnect relay installed.
When the meter is used in the Payment Meter Mode:
• The dollar balance is updated in the meter once per second based on energy consumption.
• There are 5 conversion rates configured, one for each of 4 tariff periods, and one when no
tariff period is in effect.
• The first (non-tariff) conversion factor serves as the prepay enable/disable switch. If this
parameter is 0, prepay functionality and alarms are disabled in the meter.
• The meter allows for the deduction of a fixed “facilities charge” once per day at midnight.
• There is an option to automatically disconnect the load on the 2nd prepay alarm. If the
meter has disconnected the load, the user must first increment the dollar balance above the
2nd alarm level to enable actuator control. After incrementing above the 2nd alarm level the
user may switch the load back on via the Set Actuator command. If prepay is not enabled,
the actuators may be switched on and off at any time.
Non-Volatile Memory
The following information is retained in the meter upon a power failure:
• Most recent power loss/restoration time and date. (The host can read this information to
determine when power was lost.)
• Serial numbers
• Radio settings
• Actuator setting
• Alarm options and mask
• Alarm status
10 R e s id en t i a l A N S I M et er w i t h R em o t e D is c o n n ec t an d W ir e le s s M o d em
A l ar m M e s s ag e s
• Relay IMU list and information
• Relay retry counter and interval
• Relay statistics
• Active energy accumulators
• Reactive energy accumulators
• Meter statistics: minimum and maximum voltage, frequency, active power, and reactive
power
• Prepay conversion rates and alarm settings
• Prepay dollar balance
• Meter calibration data
• Demand statistics
• Time-Of-Use schedules
• Display configuration
• Load Profile configuration and log data
The time and date are not retained in the meter upon power failure. This has two consequences:
• The host must update the meter time and date upon power restoration.
• The power restoration time and date will always be the default date and time: 1/1/2000
and 00:00:01.
Alarm Messages
When appropriate, the meter shall transmit an alarm message through the network to the utility.
The following table lists possible alarm messages.
Message
Notes
AC power failure
Notification of power failure is sent approximately five minutes after
power is restored.
Non-volatile memory errors
Triggered by checksum, CRC, or memory-test errors.
Tamper
A tilt or motion sensor triggers the tamper alarm. If a power failure
coincides with a tamper event, the tamper message preempts the final
power-failure transmission.
Prepay amount reached
See “Payment Meter Mode” on page 10.
Virtual shut-off
Reports a load when a premises is presumed vacated.
The alarm interval is set to 5 minutes. This number is not configurable. A new alarm will be
transmitted to the host via radio every 5 minutes until it is either acknowledged or cleared.
