2. INSTALLATION
To get detailed information about the installation process, please visit:
https://intellimeter.ca/pages/downloads#videos: Intellimeter i-meter®MF6 Installation &
Troubleshooting and/or Intellimeter i meter®MF3 Installation & Troubleshooting.
Verify the number of breakers is the same as the number of meters assigned for that panel board.
Follow the installation drawings. Group the assigned modules to the identified panel board.
Referring to the diagram below, CTs can be embedded in the distribution panel. If the customer has
supplied a special compartment for the meter with their electrical panel, Intellimeter will install the
meter and have the SPE-1000 field evaluation completed. Otherwise, the meter will be installed in
an external enclosure to be mounted near the electrical panel for ease of servicing.
Install the modules into their appropriate position.
Voltage connectors are fixed to the meter PCB. Contractor has to wire to the meter board and use
the wire terminals (spade connectors) provided.
Terminate the voltage reference chain to the designated, 15Amp breaker and ensure the proper
phasing retained as per drawings.
Install the communication connectors to the meter modules and dress the wires they are protected
from damage during feeder and branch circuit installation. MF series can be provided with a pulse
output cable upon request.
Communication cable is to be terminated to a junction box outside of the panel board by the
electrical contractor.
Review general information and wiring diagram.
Carefully read all the WARNING signs and notes.
Check meter serial number and other information on the meter.
All meter modules are assigned within the panel board and are identified with respect to position,
or section of breakers.
A label on the top of each unit indicates meter assignment. Follow the installation drawings that are
supplied with the units.
Do not leave the secondary CT open when current is flowing through the primary circuit. This
applies to instrument CTs as ICI milliamp CTs are self-protected.
Contact ICI if there has been a change made to the layout or if the assigned drawings do not match
the actual distribution panel layout.

3. OPERATION AND TROUBLE SHOOTING
3.1 Metering Rules
1. Current Transformers (CTs) are directional.
2. Voltage references must be in phase with the load being metered and from the same source.
Rule #1:
If the CTs are mounted in the opposite direction, the polarity of the CT will be opposite.
The arrow on the CT indicates the direction from LINE to LOAD.
Similarly, the “H1” is on the LINE SIDE.
All Intellimeter milli-Amp current transformers 100:0.8A, 200:0.1A, 400:0.1A and 600:0.1A have
self-shorting protection built into the device. They can safely be open circuited while under load.

The maximum length the CT leads can be extended is 30metres.
1 twisted pair wire only for each CT.

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. The reference voltage must come from the same 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’ phase
Line 2 = Black or ‘B’ phase
Line 3 = Blue or ‘C’ phase
Neutral = White
Note: Colour sequence may vary depending on the country and region.
Rule #3:
When the metering system is tested at Intellimeter’s factory, the CT’s are assigned to a meter
and to a specific element of that meter. The CTs are recommended to be installed and used only
with the meter and element that they have been tested with.
Each CT has been identified so it can be easily installed by following the installation drawing that
was designed for that particular distribution.
Follow the Installation Drawing! If there is a discrepancy with the drawing in comparison to your
distribution panel, call us for assistance.

5. CONFIGURATION
The i-meter® MF series meter is a mA meter, which uses any Measurement Canada approved mA
current transformers. In order to have the same meter constants, the i-meter® MF series meter must be
configured in the factory to match with the CT supplied with the meter. If the requirement changes, the
meter will need to be reconfigured at our factory.
6. i-meter®MF SERIES DISPLAY
The i-meter®MF3 and the i-meter®MF6 have a three-line LCD that shows both energy consumption and
real-time measurements.
Three-line LCD (3x9 character)
i-meter®MF3 is a single three-phase meter. It displays energy consumptions and instantaneous
measurements, such as voltage, current, wattage etc. It is a multifunctional meter. See all screens below.
Note: The “i_meter®1” indicates meter 1 measurements on this screen. The “i_meter45®2” indicates
meter 2 measurements on this screen. See below for all display functions.

7. i-meter® MF SERIES COMMUNICATION
The i-meter®MF series ModBus module enables the meter to communicate on a ModBus system. It presents
real time measurements, such as voltage, current, THD etc. The module supports ModBus RTU communication
over an RS-485 network. By default, the module communicates at 9600 bps, 8 data bits, no parity and 1 stop
bit (8N1). The communication parameters and ModBus ID may be changed through the ModBus registers.

7.2 i-meter® ModBus RTU Registers Mapping
The ModBus module has a plethora of registers that present the metering data, as well as diagnostic
information for the module itself. The bulk of the registers are available using the Read Holding Register
ModBus command, while the Read Input Registers provides direct read access to the non-volatile memory.
The system registers provide general information about the meter and the ModBus module. This
information is the identification data and it generally remains constant with the exception of the up time.
