CAUTION
* Only wire the neutral terminal if it is available on both the [Busbar] and [Source]. If neutral is only wired on one side of the
equipment it causes a difference in the reference of a star connection. The difference causes an error during
synchronisation.
6.3.2 Voltage measurements wiring
MORE INFORMATION
See Default wiring for controller types, ACM3.1 terminal connections and default wiring for more information about
the default wiring for voltage measurements.
DANGER!
DEIF recommends that you install fuses (2 A rating) on the voltage measurement lines, as close to the busbar as possible.
These fuses protect the voltage measurement lines.
6.3.3 Current measurements wiring
MORE INFORMATION
See Default wiring for controller types, ACM3.1 terminal connections and default wiring for more information about
the default wiring for current measurements.
INFO
The current inputs are galvanically separated.
