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
PV Max current
Max voltage
MIC 600-2000 TL-X
13A
500V
MIC 2500-3300 TL-X
13A
550V
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 -10
℃
, must not exceed the Max. input
voltage of the inverter.
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.
