Metering Rules#1.Current Transformers (CT’s) are directional.#2.Voltage references must be in phase with the

load being metered and from the same immediate source.

#3.CT’s are to be identified and phased in accordance with RULE# 2.

Rule #1:If the CT’s are mounted in the opposite direction, the polarity of the CT will be opposite.DOT or “H1” indicates the LINE SIDEThe arrow on the CT’s indicates the direction from LINE to LOAD.

LINE LOADHI

.All 5 Amp (X00: 5A) Type Instrument Transformers Are Required To Be Shorted Together While Under Load At All Times. A CT shorting block is provided to short the CT lines if the meter requires to be removed for service.

Rule #2:Check to verify that the voltage potential used, as a reference voltage, is the same phasing as the loads being metered. ABC is ABC not CBA or BCA. The reference voltage must come from the same immediate source. Voltage reference from another transformer is incorrect and causes inaccurate readings.

Connect the voltage reference to the meters disconnect or terminals making sure it is the same phase sequence.Usually:

Line 1 = Red or ‘A’ phaseLine 2 = Black or ‘B’ phaseLine 3 = Blue or ‘C’ phaseNeutral = White

Page - 3

Rule #3:When installing the CT’s on the feeders, pay attention to the marking or label on the CT housing to properly install them in the correct direction. Identify and label the CT’s of what phase they were installed on.

CT1 = Line 1 = Red or ‘A’ phaseCT2 = Line 2 = Black or ‘B’ phaseCT3 = Line 3 = Blue or ‘C’ phase

We have identified each CT, with a label, so it can be easily installed following the installation drawing that was designed for that particular distribution. For standard installations, CT labels are not supplied and any CT can be put on any feeder, BUT identify the phasing after installation.

Follow the Installation Drawing! If there is a discrepancy with the drawing in comparison to your distribution panel, call us for assistance.

PLEASE CALL IF ANYTHING IS NOT CLEAR. IT IS DIFFICULT AND TIME CONSUMMING TO CORRECT ERRORS ONCE INSTALLATION

HAS BEEN COMPLETED!Technical Assistance (SERVICE): 905-839-9199

Installation InstructionsAgain, call before you install if you require additional information on this process. If any of these steps are incorrect, call for assistance.

1. Confirm the drawings that were sent with the metering system are accurate. Verify the type of panel and that the distribution is the same. It is important that all assigned breaker phasing is correct.

2. Assign the proper panel to the identified distribution.

3. Verify the type of system is the same as the meter supplied, (Eg. 120/208V, 100A or 200A, 3 phase 4 wire, single phase 3 wire network system, etc).

4. Mount the panel as indicated by the drawing. Call to inquire if a different mounting configuration would work better.

5. Refer to the drawings to sort out the CT’s installation. If a generic drawing is supplied, follow rule #3.

Page - 4

6. One feeder at a time, install the CT so the DOT is on the line side or the arrow is pointing towards the load. Confirm on the drawing, the installed CT corresponds to the correct phase of the suite. Continue until all CT’s are installed.

7. Supply a voltage reference from the distribution panel. Depending on the configuration, minimum is a 15A breaker and the number of phases should match what is required on the drawing. All service, except delta type, will require a neutral wire.

8. If the system is automated, a CAT 5, 4 pair #24 (Network cable) is required to be pulled from one metering panel to the next until it reaches the communication cabinet that is usually mounted in the communication room or main electrical room. Refer to single line drawing.

9. Attached is a checklist that is to be completed, verified and faxed back to Intellimeter before commissioning is scheduled.

NOTE: The electrical contractor will provide an electrician for the duration of the commissioning for inspection and for any modification re-work required. Intellimeter is not liable to work on the electrical distribution and will only be terminating the communication lines. All deficiencies will be recorded and sent to the electrical contractor for correction before returning to site.

This key allows the user to access programming (only page 00) orthe details of the measurement.

Keys allowing the user to scroll the measuring pages, display thedetails relating to the measurements: dmM=dmd maximum value,dmd=avg value, max=maximum value, min=minimum value. In thepage relating to the meters it’s possible to read the value of theenergy counted per month (JAN...DEC), per tariff (T01...T12) andper phase (L1, L2, L3). The contemporaneous pressure of thesekeys also allows the adjustment of the display

Optical communication port (standard ANSI).

When the instrument is switched on, the operating system will beloaded; this implies a short waiting time (during this phase thedisplay shows a sand glass which will stop moving only when theloading phase is completed). Then, the instrument will start measur-ing and will display the window on the left. This page, called "P00"page, is the only page which can be configured by the user who canchoose, by means of the programming, which variables are to be dis-played in the 3 sections (a, b, c) (see “display page” in the program-ming menu). The (d) section indicates the consumption of the meas-ured energy (kWh and kvarh), a graphical indicator (d1) allows a quickreading of the % value relating to the active system power being usedwith reference to the installed power value previously set in the instru-ment. In the other measuring pages, the variable type displayed in thefour sections (a, b, c, d) is pre-established and cannot be modified.The display of the lower part of the display is common to all measur-ing pages.
