General
This instructional leaflet contains general installation instructions for the following single phase and
polyphase watthour meters:
• socket-connected meters: 1S, 2S, 3S, 4S, 5S, 6S, 8S, 9S, 10S, 12S, 13S, 16S, 26S, 29S, 35S, 36S, 45S, 56S
• bottom-connected meters: 5A, 6A, 10A, 13A, 16A, 35A, 36A, 45A
See the following technical manuals for more information about the ALPHA meter:
• ALPHA
Meter Technical Manual (TM42-2180A or later)
®
• ALPHA Meter Options Technical Manual (TM42-2181B or later)
• ALPHA Plus
Meter Technical Manual (TM42-2182C or later)
®
• A3 ALPHA Meter Technical Manual (TM42-2190A or later)
All meters are calibrated and tested before shipment. For proper installation, accuracy, and maximum
life of the meters, use the following installation procedures.
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 any current transformer secondaries (3S, 4S, 5S, 5A, 6S, 6A, 8S, 9S, 10S,
10A, 26S, 29S, 35S, 35A, 36S, and 36A meters). Equipment damage, personal injury, or death can
result if circuit closing devices are not used.
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
(see "Forms 45S, 45A, and 56S safety precautions" on page 3) as well as your authorized utility
procedures.
