DANGER
RISK OF DEATH DUE TO ELECTRI-
CAL SHOCK AND DISCHARGE!
The PV generators/cables may be
live as soon as they are exposed to
light.
IMPORTANT
INFORMATION
If incorrectly assembled, the
screws securing the cover may
seize and destroy the thread inside
the housing. Tighten the cover
screws crosswise and do not fully
tighten them immediately. This will
make the cover more centred on
the housing and prevent the screws
inside the housing from seizing.
DANGER
RISK OF DEATH DUE TO ELECTRI-
CAL SHOCK AND DISCHARGE!
De-energise the device, secure it
against being restarted and wait
five minutes so that the capacitors
can discharge.
DAMAGE POSSIBLE
If the PV generators are incorrectly
connected, the inverter may be
damaged. Check the connections
before commissioning.
