Risk of fatal injury due to high voltages
High voltages occur in photovoltaic systems (up to
265 V AC and 1000 V DC) as well as high currents
(13 A to 20 A AC and 11.6 A to 16 A DC). Failure to
observe standards, directives and local regulations
when working on the photovoltaic system leads to
risk of fatal injury. Please note the following here: The
solar generator is live during daylight.
Before starting any work on electrical systems:
Disconnect the system

Ensure that it is secured against being switched

back on
Verify that the system is fully de-energised

 Earth and short-circuit the AC system
Cover or shield any adjacent live components

Risk of fatal injury due to residual voltages
The capacitors of the string inverter may still contain
residual charges even after the device is switched off.
 Check that the system is fully de-energised using
suitable measuring equipment
Risk of fatal injury due to arcing
High DC voltages UDC = 1000 V (no zero point) may
exist in photovoltaic systems, which can cause arcing
if components such as fuses or plugs are not used in
the specified manner.
Use components of the photovoltaic system in

