Fronius IG 15 - Manual (Page 12)

4
The design and function of the FRONIUS IG unit offer a maximum of safety,
both during installation as well as in operation. A complete galvanic insulati-
on between DC and AC side guarantees maximum safety.
The FRONIUS IG takes over the tasks of galvanic insulation and network
monitoring. The passive and active measures for the protection of per-
sons and equipment are understood by this.
Whenever conditions in the electric mains network are inconsistent with
standard conditions (for example mains switch-off, interruption), your
FRONIUS IG unit will immediately stop operating and interrupt the supply
of power into the mains.
Your FRONIUS IG unit can monitor the situation in the mains in several
ways, by
- monitoring voltage
- monitoring cycle frequency
- ENS (optional)
The ENS option is compulsory in only a few countries, and only for them
the FRONIUS IG unit is available with this option. In any case however
will the monitoring and safety systems integrated in the FRONIUS IG unit
be available as standard equipment.
Only qualified installers are authorized to open the connection area.
Opening the connection area is only permitted when it is not under voltage.
The separately insulation encased power stage shall only be opened
when not under voltage and only by Fronius-trained service staff.
