Term Function Technical data Description
59 CU Current transformer
inputs, 5A-AC or 1A-
AC
Connect the terminals of current
transformers to these terminals. Do not
connect the same CT to other devices;
this may cause malfunction. Do not use
common terminals. Do not ground. Be
sure to connect each CT to the correct
terminal with the correct polarity.
Otherwise, kW and
cosΦ measurements
will be erroneous. If the measured power
is negative, reverse the polarities of all 3
current transformers. The primary value
of all 3 current transformers must be the
same. Secondary current must be either
1A or 5A. (for example 200/5 A)
