Meter and Device Schedules

[sdo]

Linked at the bottom of this article are meter installation schedules for various multi-meter devices. Ideally these are filled out by installing electrician, to then be handed to the person responsible for programming. The A8911 is not a meter in itself but does collect the usages from a basic meter so it is mainly used for naming each load. You may use this for sites that have the A8332 and only use the first eight inputs.

For any power meter, it is crucial to follow the installation diagrams in the manual to ensure phasing, wiring polarities, and CT orientation are completed per our manual. Then to document it accordingly. The install schedules below are examples of what information is needed.

In general, we suggest only use of spaces and dashes ("-"); avoid use of special characters or symbols. It is also best to try and limit the length of the label. Use of abbreviations are recommended.

For residential and commercial billing applications we would recommend meter names based on a unit, apartment, or suite number. Going by tenant names should be avoided as those have a likelihood of changing at some point.

For building efficiency programs and code compliance applications we recommend meter labels of the following:

• "Panel Name | Circuit#"
• "Panel Name | Circuit# | Abbreviated Load Category" eg. "MSB 41 INTLTG"
• "Panel Name | Circuit#-Circuit#-Circuit# | Abbr. Load Category" eg. "MSBA 20-22-24 RCPT"

Specifically for code compliance applications, when planning on how to land CTs to the meter, it is best to group like load types within the same three-phase grouping on a meter. If you would like, include an abbreviated load category in the label for ease of identification in the system. If these load categories may change later, it may be best to leave this off and maintain in separate building documentation.

List of additional examples:

1130	(all three phases go to one suite)
1112-1120-1125	(CT1 is unit 1112, CT2 = 1120, ...)
MSB-12-x-16	(use x for blank, no CT installed)
FL1A-sp-sp-11-EL	(sp denoting 'spare' CT wired in but not used, EL = exterior lighting)
MSB-A-B-C	(use of A,B,C here denote CTs are measuring the feed to the panel)

Series 7000/7100 (part# 70xxx or 71xxx) See figure 1 above for grouping sets of CTs together while keeping CT inputs 1,2,3 per each element associated with phase A,B,C, respectively. Phasing can be reassigned in meter configuration to any phase reference, but will unexpectedly increase any previously quoted programming time. Additional days of programming services may be required and would not be covered.	Download
Series 7200/7300 (part# 72xxx or 73xxx) 7200/7300 meters allow for all the CT inputs to be flexibly used to create up to 24 virtual groupings (elements) of 1,2, or 3 CT energy measurement sums. With these virtual groupings, phase rotation will need to be adhered to appropriately. One voltage phase reference (L1,L2,L3) can only be applied once per each grouping. Phasing rotation can be reassigned in meter configuration to any phase reference, but will unexpectedly increase any previously quoted programming time. Additional days of programming services may be required and would not be covered.	Download
Series 8000 [Does not include an area to denote phasing. Ensure to add this information somewhere. For fastest programming, it is recommended the electrician can install the CTs monitoring each load in the following suggested phasing patterns: A | A | A | A (single phase only to every load) A-B | A-B (commonly with split phase 120/240) A-B | C-A | B-C (3 phase 120/208 service with two poles to each load) A-B-C | A-B-C (3 phase to each load) Phasing can be reassigned in meter configuration to any phase reference, but will unexpectedly increase any previously quoted programming time. Additional days of programming services may be required and would not be covered.	Download
