PT 30k to PT 33k
Note the AC terminal assignment. An incorrect assignment can result in the
unit being destroyed.
No consumers may be connected to the supply line from the Solar Inverter to
the mains fuse.
Always disconnect the mains connection first by switching off the correspon-
ding mains fuse and before disconnecting the solar generator side by ope-
ning the DC load break switch.
NOTE
If the voltage on the AC connection exceeds the permissible value due to a long
line length or an insufficient cable cross-section, the Solar Inverter will be dis-
connected from the mains. In power grids with a low capacity and a high solar
generator output, this can lead to individual Solar Inverter being switched off
and then on again several times.
Overview
An AC terminal strip on the underside of the unit is used for the five-wire grid
connection (L1, L2, L3, N, PE) of the solar inverter. Feeding is always three-phase
via the AC terminal.

The unit is centrally earthed using PE terminals. No separate earthing of the so-
lar generator is required.
