Connecting backup power - PV Point (OP)
Safety 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).
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.
▶
Do not connect any loads that require an interruption-free supply.
WARNING!
Danger from incorrect installation, commissioning, operation or incorrect use.
This can result in severe personal injury/damage to property.
▶
Only trained and qualified personnel are authorised to install and commis-
sion the system, and only within the scope of the technical regulations.
▶
The Installation and Operating Instructions must be read carefully prior to
use.
▶
If anything is unclear, contact your vendor immediately.
WARNING!
Danger due to damaged and/or contaminated terminals.
This can result in serious injury and damage to property.
▶
Before making any connections, check the terminals for damage and con-
tamination.
▶
Remove contamination in the de-energized state.
▶
Have defective terminals repaired by an authorised specialist.
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 the
earth.

Point (OP) on page 175 .
