Protection class of PV modules
The inverter must only be operated with PV modules of
protection class II, compliant with IEC 61730, application
class A.
Only connect PV modules to the inverter. Other energy
sources are not allowed.
PV modules generate a voltage when exposed to light.

3.1 User Interface
The user interface comprises:
• Local display, for all inverter variants. The local display
shows status information of the inverter. It is not
possible to set up or configure the inverter via the
display. The "#" in the display explains the operation
modes.
• Local commissioning and service tool (LCS-Tool). The
LCS-Tool can be used for configuring one or more
inverters.
