5 Commissioning
Before commissioning the inverter, be sure the following steps have been completed:
 Confirm the correct power supply connection
 Confirm the correct connection of PV strings
 Confirm that connectors are protected such that they cannot be pulled off inadvertently
DANGER
Danger to life from electric shock
 Before switching on the device, check whether the plugs are securely
fitted (locked).
Do not pull off the connectors of the PV generator before you have met the
following requirements:
 Make the power supply line absent of voltage.
 Make the device absent of voltage using DC circuit breaker.
 Check that the DC cables of the PV generator are de-energized.
 Protect the voltage supply from being reactivated
DANGER
Risk of electric shock and fire caused by high discharge current.
 Before connecting the device to the supply circuit, establish a ground
connection.
5.1 Turning on the Device
1. Verify that the device is connected to line voltage. If not, insert the external power fuse or turn on the
circuit breaker.
2. Apply voltage by turning on the DC switch. The inverter only starts if there is sufficient voltage available
from the PV panels.
5.2 Setting the Country Code and the Menu Language
When switching on for the first time an initial configuration is necessary.
The country code defines the country-specific grid monitoring parameters. The menu language is
automatically set when the country code is selected. The menu language can subsequently be selected as
Note:
The control panel, including its status indicators, display, and operator keys,
is only active when the PV generator is supplying sufficiently high voltage.
