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
Risk of electric shock!
● Before switching on the device, check whether the connectors are securely
fitted (locked).
● Do not pull off the connectors of the PV generator before you have met the
following requirements:
VORSICHT
- Set the DC isolator on the inverter to "OFF".
- Check whether the DC cables of the PV generator are de-energized.
- Enable the power supply line and protect the voltage supply against being
reactivated.
Risk of electric shock and fire caused by high leakage current!
Before connecting the device to the supply circuit, establish a ground connection.
CAUTION

5.1 Turn on the Device

a. Verify that the device is connected to line voltage. If not, insert the external power fuse
or turn on the circuit breaker.
b. Set the DC isolating switch on the inverter to the ON position.
The inverter will not start running with connected PV field before the DC isolator is
switched on.

The control panel is only active with activated DC voltage. The control
panel, including its staus indicators, display and operator keys, is only
active with activated DC voltage because the electronics of the inverter is
exclusively supplied from the DC side.
