1 October 006 IL4-400Q ALPHA Meter Installation Information General This instructional leaflet contains general installation instructions for the following single phase and polyphase watthour meters: socket-connected meters: S, S, S, 4S, 5S, 6S, 8S, 9S, 0S, S, S, 6S, 6S, 9S, 5S, 6S, 45S, 56S bottom-connected meters: 5A, 6A, 0A, A, 6A, 5A, 6A, 45A See the following technical manuals for more information about the ALPHA meter: ALPHA Meter Technical Manual (TM4-80A or later) ALPHA Meter Options Technical Manual (TM4-8B or later) ALPHA Plus Meter Technical Manual (TM4-8C or later) A ALPHA Meter Technical Manual (TM4-90A 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 (S, 4S, 5S, 5A, 6S, 6A, 8S, 9S, 0S, 0A, 6S, 9S, 5S, 5A, 6S, and 6A meters). Equipment damage, personal injury, or death can result if circuit closing devices are not used. 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 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.

2 IL4-400Q October 006 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: Mount the bottom-connected meter or the bottom-connected S-to-A adapter. 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. Wire the meter. See the wiring diagrams beginning on page. 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 00 amp meters, use # wiring (or in accordance with standard utility operating practices) For 50 amp meters, use # AWG or 50 mm 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 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. Installation Wiring All available ALPHA meter forms are listed and separated with respect to the type of service being metered. Use of Form 9S, 0S, and 0A (in 8S and 8A applications), and Form 6S (in Form 5S application) are also shown. Form 4S and 4A applications are simply 4 wire WE services and would be metered by Form 6S and 6A. 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. ot supplied by Elster Electricity, LLC.

11 October 006 IL4-400Q 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 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: relay with 6 output leads (see Figure ) relays with 6 output leads (see Figure ) 4 relays with 8 output leads (see Figure ) 4 relays with 9 output leads (see Figure ) 6 relays with output leads (see Figure 4) In all cases, the output leads exit the meter using approximately 4 inches of cable. Regardless of the configuration present, the relays are assigned as follows: For ALPHA and ALPHA Plus meters: is dedicated to kwh delivered. is dedicated to kvah delivered (for A or A+ meters) or kvarh delivered (for AR or AR+ meters) When present, is dedicated to kwh received. When present, 4 is dedicated to kvah received (for A or A+ meters) or kvarh received (for AR or AR+ meters) For A 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 A ALPHA Meter Technical Manual (TM490B or later) and the Metercat User Guide (TM4-04B or later) for specific information.
