Installation and operating instructions
QX³ series
DANGER from fire
Fire resulting from insufficient fuse protection of the PV inputs or the PV strings
NOTE
The relevant DC string configuration must be configured in the display
(Installation Assistant) (see Chapter 5.17) or via the web server (see Chapter 7
Operation and monitoring via the web interface).
CAUTION
If the DC string configuration is not configured correctly, the MPP cannot be
optimised. There is risk of loss of yield.
The plus and minus connections of different MPP trackers must not be
connected to each other.
The following threshold values for the DC input of the inverter must not be
exceeded:
