advisable to install the Meter in the distribution board as the
appliance is neither waterproof nor dustproof.
2.2.3
CTs connection
Connect outputs of three current transformers to six inputs of
Meter (CT Current Input), matching terminals white I* and
blue I of CTs with IA* and IA, IB* and IB and IC* and IC inputs
as in the figure below.
Then, close and ensure the three CTs to respective phases
of power connection.
Check that the arrow printed on the CTs indicate the direction
of the load. It is advisable to install the CTs in the distribution
board as the appliance are neither waterproof nor dustproof.
