Connecting backup power - PV Point (OP)
Safety
WARNING!
Danger due to work that has been carried out incorrectly.
This can result in serious injury and damage to property.
▶
Installing and connecting an option must only be carried out by service per-
sonnel trained by Fronius and only within the scope of the respective tech-
nical regulations.
▶
Follow the safety rules.
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.
NOTE!
During the switch from grid-connected operation to backup power mode, mo-
mentary interruptions will occur. The PV Point output requires PV power from
the solar modules or a battery to power the connected loads.
Connected loads will not be supplied with power during the switchover.
▶
Do not connect any loads that require an uninterruptible supply ( e.g. IT net-
works, life-sustaining medical devices).
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.
For the Circuit Diagram recommended by Fronius, see Circuit Diagram - PV
Point (OP) on page 213.
