Danger due to blocked escape route
Opening the doors of two Sunny Central inverters located opposite each other blocks the escape route. It is imperative
that the escape route is freely accessible at all times. Make sure the minimum passage width of the route meets local
standards. In Germany, the minimum passage width is 500 mm.
• Only open the door of one Sunny Central at a time.
• Comply with local requirements concerning minimum passage widths.

Laying the cables
This manual does not specify at what stage the cables are to be laid in the foundation. The stage at which the cables
are laid must be determined individually for each PV system.
