✧
Enter the desired values in the fields and select the parameters in the list boxes and option fields as
described in Table 7-2.
✧
If you are not using a voltage transformer and/or current transformer between the measurement object
and SICAM MMU, click
no
in the respective option field. The associated fields for primary and secondary
values are hidden in this case.
✧
In the
Calculate VN
option field, select whether to calculate (
yes
) or measure (
no

.
NOTE
The option field
Calculate VN
is only visible in the device variants SICAM MMU 7KG9663-1AA00-xAA0 (de-
vices with a voltage divider at the voltage measuring inputs).
The voltage in the neutral conductor is calculated if it is grounded (standard).
The voltage in the neutral conductor is measured if b is grounded (special connection type).
