Installation
Connecting solar module
Only solar modules of the following category may be
connected: Class A as specified in IEC 61730.
1.
The PV strings may only be connected to the inverter
when the housing is closed.
Install the cover and screw it tight (5 Nm).
2.
De-energise the inverter.
3.
If there is more than one inverter in a PV system,
ensure that no cross-connection occurs when the PV
generators are connected.
Fig. 31: Incorrect connection of PV generators
4.
Check the strings for earth faults and short circuits
and correct these where appropriate.
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.
