7 Maintenance and
disassembly
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 injury due to lack of earthing
Without an earth connection, the housing of the
inverter could become live in the event of a fault,
which could lead to serious injury or death.
Therefore, always observe the following sequence
when disconnecting the DC and AC cables:
Move the service switch from 1 to 0

Disconnect the DC cable

Then disconnect the AC cable

 Finally, disconnect the earth connection
