Revision 1.8.3
6.3.1.2 Current Transformer B
The ACM100 with firmware revision 1.0.7 or newer supports two different types of current sensors:
the 100A current sensor included with the unit and an optional 400A current sensor. This menu entry
allows you to indicate which type of current sensor you have installed for phase B.
6.3.1.3 Current Transformer C
The ACM100 with firmware revision 1.0.7 or newer supports two different types of current sensors:
the 100A current sensor included with the unit and an optional 400A current sensor. This menu entry
allows you to indicate which type of current sensor you have installed for phase C.
6.3.1.4 Current Transformer A
If you notice that the power measurements of phase A are negative when they should be positive, or
vice-versa, then the current transformer has been installed backwards. If this happens, then instead
of reconnecting the current transformer, you may change the value of this parameter from the default
value
of “Normal Install” to “Inverse Install” to correct for this.
Valid options are:
•
Inverse Install
•
Normal Install
Use the
Scroll Up
and
Scroll Down
buttons to select the correct option, and then press
Enter
to
save the value.
6.3.1.5 Current Transformer B
If you notice that the power measurements of phase B are negative when they should be positive, or
vice-versa, then the current transformer has been installed backwards. If this happens, then instead
of reconnecting the current transformer, you may change the value of this parameter from the default
value of
“Normal Install” to “Inverse Install” to correct for this.
Valid options are:
•
Inverse Install
•
Normal Install
Use the

save the value.
6.3.1.6 Current Transformer C
If you notice that the power measurements of phase C are negative when they should be positive, or
vice-versa, then the current transformer has been installed backwards. If this happens, then instead
of reconnecting the current transformer, you may change the value of this parameter from the default
