2.10 Closure

1. Close the cover of the inverter installation area. Fasten
the three front screws (see Section 5.4, page 43).
2. Turn on AC power.

3 Initial Setup and Start

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.

3.1.1 Operating Modes

The inverter has five operation modes, indicated by LEDs.
Status
Off grid
Connecting
On grid
Internal inverter event
Fail safe
Table 3.1 Operating modes
Off grid (LEDs off)
#0-51
When no power has been fed into the AC grid for more
than 10 minutes, the inverter disconnects from the grid and
shuts down. User and communication interfaces remain
powered for communication purposes.

Once the PV input voltage reaches the DC initial voltage,
the inverter goes into operation. The inverter performs a
series of internal self-tests, including measurement of the
resistance between the PV array and ground. Meanwhile, it
also monitors the grid parameters. If the grid parameters are
within the specifications during the required period
(depending on the grid code), the inverter starts feeding into
the utility grid.
On grid (green LED glowing)
#60
The inverter is connected to the AC grid and feeds into the
grid. The inverter disconnects from the utility grid in the
following cases:
• The inverter recognizes abnormal grid conditions
(depending on the grid code).
• An internal event occurs.
• PV power is insufficient (no electric current has been
fed in for approx. ten minutes).
Internal inverter event (green LED flashing)
#54
The inverter waits for an internal state within the thresholds
(e.g. due to too high a temperature) before reconnecting to
the utility grid.
Fail safe (red LED flashing)
#70
If the inverter detects an error in its circuits during the self-test
(in the "Connecting" operating mode) or during operation,
it switches over to the "Fail safe" operating mode and is
disconnected from the utility grid. The inverter remains in the
"Fail safe" operating mode until the PV power has been
absent for ten minutes or the inverter has been shut down
completely (AC+PV).
