6.1 Voltage Input
Voltage input should be less than 120% normal voltage (100V or 400V), otherwise
please use PT. On the voltage input, please use a 1Amp fuse. The wiring should be
as our diagrams on page 5.
Mode of wiring
1 element
1P2W
2 element
3P3W
3 element
3P4W
Match the voltage input with current input, and match the phase and phase
sequence (otherwise the values or signals will be incorrect).
6.2 Current Input
Normal current input is 5A, for more than 5A you must use Current transformers.
Make sure that you follow the connection details carefully when connecting the
voltage and current circuits to the meter.
6.3 Installation of Current Transformer
It is good practice to use a test shorting block where the external current
transformers can be linked out should the meter ever need replacing.
6.4 RS485 Modbus Wiring
The IC 995 is fitted with an RS 485 Modbus output. It has been designed to work
with Autometers protocol version V6.2.17, which enables up to 128 meters to be
connected on one Lan circuit. We advise using Beldon cable 9841 or 9842.
7. Features available
7.1 Main menu:
When the meter has voltage applied to the auxiliary
terminals (12 and 13) the meter will go through a
set up routine. Firstly the display will show
Autometers' front page then it will go to the first
screen (01), the line voltage screen.
Press Menu to view the various optional parameters.
