•
Introduce the wires into the screw connections in the contact insert and tighten.
i
Ensure that the conductors are securely fixed in the connections.
•
Introduce the contact insert into the plug housing. Both parts must audibly latch into each other with
the side detents.
•
Tighten the cap nut for tension relief.

Connecting the VARTA Split Core current sensor
If the energy store to be installed is to be cascaded with further energy stores, the following work step is
not
performed. Instead, see the operating manual for the cascading. (Optional extra package required)
ATTENTION
Inverted phases.
Fault of the charging and discharging function.
The house connection must be executed as a
clockwise rotating field
.
Conductors L1, L2, L3 for house connection, current sensor and AC plug must have
the same phase assignment.
It is not sufficient to execute the connection as a
clockwise rotating field
.
ATTENTION
Soiling of the magnetic cores.
Current sensor is damaged.
Do not touch the magnetic cores.
Ensure a clean working environment.
To ensure the own consumption optimisation, the house network current sensor must record all values of
consumption and infeed. For this reason, it is located right behind the consumption and feed-in meter. The
VARTA Split Core Stromsensor consists of a terminal box and three folding transducers. Their nominal current is
50 A (maximum current 100 A) per phase. The terminal box is designed for top hat rail mounting. The connection
for the sensor cable included in the delivery for connecting to the energy storage system is found in the
terminal box. For the position of the “current measurement” socket on the energy storage system, see Figure 3:
Back of storage cabinet on page 52.
