CAUTION
If the inverter is not equipped with a DC switch but this is mandatory in
the country of installation, install an external DC switch.
The following limit values at the DC input of the inverter must not be
exceeded:
Types
7000-8000 TL-X(E)

6.4.2 Connecting the PV Array (DC input)
DANGER
Danger to life due to lethal voltages!
PV array supplies d.c voltage to inverter when exposed to light,before
connecting the PV array, conver some light screens above PV
arrays,ensure that the DC switch and AC breaker are disconnect from
the inverter. NEVER connect or disconnect the DC connectors under
load.
Make sure the maximum open circuit voltage(Voc) of each PV string
is less than the maximum input voltage of the inverter.
Check the design of the PV plant. The Max. open circuit voltage, which
can occur at solar panels temperature of -15
℃
, must not exceed the
Max. input voltage of the inverter.
WARNING
WARNING
Improper operation during the wiring process can cause fatal injury to
operator or unrecoverable damage to the inverter. Only qualified
personnel can perform the wiring work.
Please don’t connect PV array positive or negative pole to the ground,
it could
cause serious damages to the inverter
Check the connection cables of the PV modules for correct polarity and
make sure that the maximum input voltage of the inverter is not
exceeded.
