Performance and data
Overview
The IC7-C and IC9-C meters are 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 a fully programmable
RS485-communication output and is capable of
transmitting all of the data the meter monitors.

Current transformer selection
For accurate monitoring, correct selection
of the current transformers is critical.
Always select the current transformers suitable
for the load you are actually monitoring.
DO NOT automatically select current
transformers to the breaker size
in case the load is significantly lower.
