4.1 Installation
IC995 is a 96mm square panel mounted meter and is installed by inserting the back
of the meter through a hole in the front cover plate and locking it in position by
two metal fixing clips which can be adjusted on the back.
4.2 Installing the IC 995
. Create an opening on the switchboard of 92 x 92 mm.
1
. Remove the IC 995 from the box, undo and remove the two metal fixing clamps
2
on the back.
3
. Taking the meter in your hand. Insert the meter through the hole in the front
plate, slide the two metal fixing clamps down the side and screw the fixing
screws tightly. This should now have secured the meter into the panel.
Power Supply
Power supply auxiliary terminals (12 + 13) AC/DC 85-270v
Wiring
Electrical and communication connections are made directly to the back of the
meter.
See diagram to right.
There are three blocks of green connectors, the two at the top can be unplugged, the
one at the bottom is screwed into position. This
connector terminates the current transformers
into the meter and should not be unplugged
unless necessary.
This connector can only be removed if the
current transformers have been shorted out.
These connectors should not be removed with
power still on the meter. Choosing the correct
cable to be used for the wiring of the current
transformers to the meter depends on the
rating of the current transformers used and
the distance the current transformers are from
the meter.
E.g. if the current transformers are minimum
2.5 va and are within 2 metres of the IC 995 then
we recommend 1.5 multi stranded cable
(Autometers Part number 995CH).
