NOTE!
The continuous supply via the PV Point depends on the available PV power.
If the solar modules are not supplying enough power, interruptions may occur.
▶
IMPORTANT!
The valid national laws, standards and provisions, as well as the specifications of
the relevant grid operator are to be taken into account and applied.
It is highly recommended that the specific installation be agreed with the grid
operator and explicitly approved by this operator. This obligation applies to sys-
tem constructors in particular (e.g. installers).

Installation

NOTE!
All loads that have to be supplied via the OP terminal must be protected by
means of a residual-current circuit breaker.
In order to ensure the residual-current circuit breaker operates properly, a con-
nection must be established between the neutral conductor N´ (OP) and earth.

WARNING!
Before making any connections, check the terminals for damage and con-
tamination.
