Overview
The IC7-C and IC9-C meter is
230/400 volt 50 Hz, 5 amp current
transformer operated meter
designed for measuring 3 phases
in a 4 wire star configured system
and is capable of transmitting
kWh and KVAh by means of
the volt free outputs which are
standard on the basic model. The
model IC9-C is supplied with fully
programmable RS485-Modbus
communication output and is
capable of transmitting all of the
data the meter monitors.
Installation
Orientation
The meters are designed to be
fitted into a panel, normally a
switchgear cabinet. It is therefore
recommended that the front of
the meter is positioned vertically
with adequate space around and
at the back for connections.
Location
The meters should be mounted in
a dry dirt free environment away
from all heat sources and very
high electric fields. Temperatures
should not exceed 70°C or fall
below -20°C.
Installing the meter.
First remove the meter from the
packaging and check for any
damage. The meter should be in
two pieces, a Front Bezel and the
back of the meter. (See diagram
1 above) The aperture required to
fit the meter is 92 mm x 92 mm.
Holding the back of the meter
in one hand and the bezel in
the other hand, present to the
opening. Slide the back of the
meter first through the opening
on the rear side of the door and
then push the bezel from the
front side over the protruding
clear plastic and push fully
home until it locks firmly.
Please note it is extremely
difficult to remove when fitted.
Please see diagram 1.

Phasing and polarity of the AC
current and voltage inputs and
their relationship is critical to the
correct operation of this meter.
The connection diagram shows a
current transformer fitted to the
Neutral.
If you do not want to monitor the
neutral current it is not necessary
to connect to terminals 7 and 8.
Terminal 9 is the Neutral supply
Terminals 10,11,and 12 are the
three phase line voltages (230
volt). Terminals 14,15, and 16 are
the low voltage pulse output. (volt

Wiring information
Power supply
The standard IC9 requires a 230
volt 50 Hz supply. This is powered
from the L3 phase and Neutral
internally.
Wiring
Electrical and communication
connections are made directly to
the back of the meter.
The main electrical connections are
made to terminals 1-16 at the lower
half of the meter, Communication
Modbus 485 connections are made
via the two sockets at the top of the
meter on the side. Please see dia 2.
Programming
the CT Ratio '13'
To programme the CT Ratio the
dill switch number "8" on the
lower dill switch block must be in
the "On" position
See diagram 6 for position of dill
switches.
Connect power to the meter.
To programme, press the
function key on the front of the
meter, which will then take you
into the display sequences for
programming the CT Ratios.
You should now see the screen
below
Diagram 3: Programming Screen
(a) You will notice the cursor
flashing on the first "zero", by
pressing the "Energy" key the
zero will change to 1, if you press
the "Energy" key again it will
change to 2 and so on.
(b) If you go past your number
continue going through the
numbers until the number you
require reappears. Stop at your
correct number '1'.
(c) Press the "Enter" key and the
flashing cursor will move to the
right. Stop at number '3'. Press
function.
Diagram 4 : CT Setting Screens
(d) Repeat steps (a) to (c) to enter
the correct programming details
for your chosen CT ratios.
(e) When the process is complete
press the "Function" key to take
you back to the default screen.
Note: When setting CT ratios and
if you have only three digits you
must enter "0" as the first digit.
e.g. 100/5 would be entered as
0100/5.
When you have programmed the
meter, disconnect the power to
the meter and ensure dill switches
are set to the 'OFF' position.
Operating
information
Power on
After you have programmed the
meter and you have put power
onto the meter, the first screen
to appear will indicate details of
the meter and your programmed
parameter values. After 10
seconds will revert to normal
default screen. "b"
a) Power On:
b) Normal Default Display

At this stage it is advisable to check
the connection to the meter, to do
this please see page 6 function 50.
This will enable you to see if the
current transformers have been
connected correctly and the three
voltages are present.
Diagram 5: Connection Check Screen
The diagram above is showing
that the current transformers
are correct and the three phase
voltages are correct.
If the current transformers are
correct but the voltage on each
phase is missing or below 200
volts, then the screen will look as

Wiring Information
Power Supply
The standard IC7-C and IC9-C
requires a 230 volt, 50Hz supply.
This is provided from the L3
phase and Neutral internally.
Wiring
Electrical and communication
connections are made to
terminals 1-6 at the lower half
of the meter. Communication
Modbus 485 connections are
made via the two sockets at the
top of the meter on the side.
Please see diagram 3.
Programming the
Meter
To program the meter the dill
switch, number “8” on the lower
dill switch block must be in the
“on” position.
Programming the Modbus
Meter Register
Each meter that is connected to
a Local Area Network (LAN) must
have a unique modbus register
so that it can be identified by the
computer processor. Allocating
a meter modbus register is
accomplished using the upper
block of dill switches. The dill
switches in this block each
represent a number, in geometric
progression starting with dill
switch number “8”. Thus switch
number “8” represents register
number “1”, switch number “7”
represents register number “2”,
switch number “6” represents
register number “4”, switch
number “5” represents register
number “8” and so on.
To allocate a meter register
number the required dill switches
must be switched into the “on”
(up) position.
Thus: To allocate meter register
number “1”, only dill switch
number “8” on the upper block
of dill switches needs to be in the
“on” position.
To allocate meter register number
“14” dill switches numbers “5”,
“6” and “7” must be in the “on”
position.
To allocate meter register number
“39” dill switches numbers “3”,
“6”, “7” and “8” must be in the
“on” position. Etc.
Programming the
Meter Functions.
The operating functions of the
meter, such as baud rate, data
format etc are programmed using
the lower block of dill switches,
as follows:
Baud Rate
Programming the Baud rate
utilises dill switches numbered
“1” and “2” on the lower dill
switch block, as follows:
Baud Rate Dill Switch Dill Switch
