• During installation, cover the PV modules with opaque material.
DANGER
High voltages in the DC cables.
Risk of death or serious injury from touching a DC cable.
• Only connect the DC cable from the PV module to the inverter as described in this
manual.
NOTICE
Potential damage to the inverter due to overvoltage.
• The DC input voltage of the PV modules must not exceed the maximum values of the
inverter. Observe the information on the type label.
• Check the polarity and the open-circuit voltage of the PV strings before connecting
the DC cables to the inverter.
• Configure the DC input voltage range accordingly before connecting the PV modules
