Socket-connected installation
Before you install the meter, check the following:
• Are the socket and meter current class ratings compatible with the meter?
• Is the wiring to the meter socket correct? See the wiring diagrams on the following pages.
• Is a lightning arrestor present? If so, remove the paint from the socket rim where it contacts the
arrestor's ground strap. This will ensure proper grounding.
• Is the TEST button in the unlocked position? If the TEST button is in the locked position, the meter will
enter TEST mode when you install it. For more information, see the technical manual for your meter.
After you install the meter, check the following:
• If load is applied, check that the pulse arrows on the LCD are blinking.
The LCD has 2 sets of pulse arrows, one located above the other. The upper set of arrows indicates
watthours, and the lower set indicates alternate energy (kVARh or kVAh, if available). The arrows
pointing to the left indicate energy received; arrows pointing to the right indicate energy delivered.
For more information, see the technical manual for your meter.
Bottom-connected installation
Before you install a bottom-connected meter, check the following:
• Determine where the meter is to be installed. It should be on a flat wall at the point of electrical
service entrance cables.
• Are the meter class and service connections compatible with the meter?
To install a bottom-connected meter, perform these steps:
1 Mount the bottom-connected meter or the bottom-connected S-to-A adapter.1
Use authorized utility procedures to install ground connection before wiring. Dangerous voltages are
present. Equipment damage, personal injury, or death can result from wiring an ungrounded meter.
2 Wire the meter. See the wiring diagrams beginning on page 3. If the wire diagram is larger than the
wire, use only approved adapters. External meter wiring should be consistent with the meter class
rating.
- For 100 amp meters, use #2 wiring (or in accordance with standard utility operating practices)
- For 150 amp meters, use #1 AWG or 50 mm2 wiring (or in accordance with standard utility
operating practices)
- For transformer rated meters, use #9 wiring (or in accordance with standard utility operating
practices)

After you install a bottom-connected meter, check the following:
• If load is applied, check that the pulse arrows on the LCD are blinking.
The LCD has 2 sets of pulse arrows, one located above the other. The upper set of arrows indicates
watthours, and the lower set indicates alternate energy (kVARh or kVAh, if available). The arrows
pointing to the left indicate energy received; arrows pointing to the right indicate energy delivered.
For more information, see the technical manual for your meter.
• The TEST annunciator is not blinking. If it is blinking, then remove the meter from service, remove the
cover, and rotate the TEST button so that the meter is placed out of test mode. For more information,
see the technical manual for your meter.
Forms 45S, 45A, and 56S safety precautions
Form 45S, Form 45A, and Form 56S meters present additional risks of electrical shock that may result
in severe personal injury or death when the cover is removed from energized meters unless certain
additional safety procedures and precautions are followed. Be sure to follow the safety procedures
and precautions when servicing Form 45S, Form 45A, and Form 56S meters as stated in this manual
as well as your authorized procedures.
When using Forms 45S, 45A, and 56S meters, be sure to understand and follow the important safety-
related concerns.
• Form 45S meters: safety concerns exist with Form 45S meters in any application in which socket jaw
7 is not grounded.
• Form 45A meters: safety concerns exist with Form 45A meters in any application in which the
equivalent terminal to the Form 45S socket jaw 7 is not grounded (A-base voltage terminal #6, as
numbered from left-to-right).
• Form 56S meters: safety concerns exist with Form 56S meters in any application in which socket jaw
16 is not grounded.
These safety concerns include, but are not necessarily limited to, the following:
• 3-wire delta applications
• dual single phase “star” configurations (may also be referred to as 5-wire, 2-phase)
• 4-wire delta applications in which the high leg is not tied to phase C
The primary safety concerns in these applications are as follows:
1 The meter battery terminals and circuit board electronics will be at line potential.
2 The circuit board electronics of any installed option board will be at line potential.
3 Any internal antenna or other electrical extension of any installed option board will be at line
potential.
It is important to assess the potential hazards after removing the meter cover and disconnect the
electrical power as necessary to perform service.

Installation wiring
All available ALPHA meter forms are listed and separated with respect to the type of service being
metered. Use of Form 9S, 10S, and 10A (in 8S and 8A applications), and Form 16S (in Form 15S
application) are also shown. Form 14S and 14A applications are simply 4 wire WYE services and would
be metered by Form 16S and 16A. The more complicated wirings are shown using both PTs and CTs.
The socket ground is shown for safety considerations. The neutral-to-ground connection is shown for
example only. Actual neutral-to-ground connection should be performed within the operating utility's
standard practice.

Battery installation and replacement
Time-of-use meters are typically shipped with the battery installed and connected. If the battery is
requested to be shipped disconnected, separately, or as a replacement, see the technical manual for
procedures for battery installation or replacement.
It is important that the battery not be connected unless the meter has been powered for at least 1
minute from the AC line within the last hour. It is important that the meter is not energized while the
battery is being installed or replaced (see the technical manual). After connecting the battery and re-
energizing the meter, the display should be checked to verify proper operation (that is, scrolling from
one display quantity to the next). Failure to follow the correct sequence for battery connection can
result in early battery discharge, the register being inoperative, or both.
Relay output color coding
Multiple relay output configurations are available with high voltage, solid state relays. The relay outputs
can be identified based on the number of output leads and their color coding. The following
configurations are available:
• 1 relay with 6 output leads (see Figure 1)
• 2 relays with 6 output leads (see Figure 1)
• 4 relays with 8 output leads (see Figure 2)
• 4 relays with 9 output leads (see Figure 3)
• 6 relays with 12 output leads (see Figure 4)
In all cases, the output leads exit the meter using approximately 24 inches of cable. Regardless of the
configuration present, the relays are assigned as follows:
• For ALPHA and ALPHA Plus meters:
- KYZ1 is dedicated to kWh delivered.
- KYZ2 is dedicated to kVAh delivered (for A1K or A1K+ meters) or kVARh delivered (for A1R or A1R+
meters)
- When present, KYZ3 is dedicated to kWh received.
- When present, KYZ4 is dedicated to kVAh received (for A1K or A1K+ meters) or kVARh received (for
A1R or A1R+ meters)
• For A3 ALPHA meters:
- All relays are fully programmable. Sources for the relays can be any basic metered quantity, EOI,
load control, PQM test failure, or relay-related alarm condition. See the A3 ALPHA Meter Technical
Manual (TM422190B or later) and the Metercat User Guide (TM42-2204B or later) for specific
information.
