2. INSTALLATION
You can visit https://intellimeter.ca/pages/downloads#videos / Intellimeter i-meter®45 Installation
&Troubleshooting to get detailed information about the installation process.
WARNING:
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.
Install the voltage connectors to the meter modules and dress the wires so they are protected
from damage during feeder and branch circuit installation.
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.
Communication cable is to be terminated to a junction box outside of the panel board by the
electrical contractor.
2.1. i-meter®45 Wiring Guide
In the i-meter®45 wiring diagram figure below, the branch CTs connect to Port A, B, C, D using a
ribbon cable.
Port A: CT1 –CT12
Port C: CT13 –CT21
Port B: CT22 –CT33
Port D: CT34 –CT42
CT43, CT44, CT45 are connected directly to the meter module with 2 pin connectors.
Voltage Input: L1, L2, L3 and N
Display- MC required- optional only if non-sealed: i-meter®45 MDU = meter display unit- comes
with a 6 ft. cable for connecting directly to the meter.

2.2. i-meter®45 Current transformers (CT) Rail
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.
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
refers 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.

2.3. i-meter®45 Current Transformers (CT) Interface Board
Referring to the installation drawings, mount the module, complete with mounting brackets,
to the back frame rail.
The CT rails are to be permanently fastened to the interior panel rails in their designated
position; this serves for spacing and support for the CTs.
Dress in the CT wire back to the metering modules to protect it from damage during feeder
and branch circuit installations.
Any CT that is not connected to the proper metering module will give incorrect readings.
All CT wire connectors and terminal position on the meter module are identified. Polarity of CT
is VERY important- white is positive, black is negative- note arrow for load/line direction.
Typically, the CT leads do not need to be removed from the meter module. If required, connect
the CT wire connector to the identified terminal on the correct meter module. There may be
several modules within a panel board, confirm the meter number on the CT connector label.
Install the voltage connectors to the meter modules and dress the wires so they are protected
from damage during feeder and branch circuit installation.
Terminate the voltage reference chain to the designated 15Amp breaker and ensure the
proper phasing retained as per drawings.
Install the communication cables to the meter modules and dress the wires so they are
protected from damage during feeder and branch circuit installation.
Communication cable is designed to be terminated to a junction box outside of the panel
board by the electrical contractor.
The 12 CT rail can replace the requirement for the CT interface box in certain situations. The CTs
must be mounted on a rail and the loads should be 100A or 200A. If there are any 400A or 600A
loads, the CT interface box must still be used.

3. i-meter®45 METER DISPLAY MODULE (MDU DISPLAY)
The Meter Display Module (i-meter®45 MDU) displays customer information, real time measurements,
total energy consumption, and power quality of each customer by using the key pad “UP”, “DOWN” and
“SELECT”.
i-meter®45 MDU Display
4. i-meter®45 MODBUS MODULE
The i-meter®45 ModBus module enables the meter to communicate on a ModBus system. It presents
real time measurements, such as voltage, current, THD etc. The normal mode of the module supports
RTU ModBus communication over an RS-485 network. Within 30 seconds of power up, the module will
enter the normal mode of operation that supports ModBus communication. 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 or through the Recovery Mode.
