Connect the cables
Connect the cables in the junction box in accordance with
the electrical system at the location. See the illustration

of 5 Nm.
If you install the system on a three-phase IT network,
we recommend that four-core cable be used in case
Electrical connection
There are four possible connection variants, depending on whether three-phase
or single-phase is used, and whether a TN network, TT network or IT network is
used, as shown under or on the label on the back plate.
