5 Disconnecting the Inverter from Voltage Sources
Prior to performing any work on the inverter, always disconnect it from all voltage sources as
described in this section. Always adhere to the prescribed sequence.
Danger to life due to electric shock from destruction of the measuring device
due to overvoltage
Overvoltage can damage a measuring device and result in voltage being present in the
enclosure of the measuring device. Touching the live enclosure of the measuring device results in
death or lethal injuries due to electric shock.
• Only use measuring devices with a DC input voltage range of 1000 V or higher.
Verifying the inverter firmware version before removing the assembly
The inverter supports different firmware versions to fulfill different grid-connection requirements.
With the firmware version ≤ 2.99.99.R, the inverter fulfills the grid-connection requirements
valid until April 26, 2019 within the EU. Grid-connection requirements outside the EU are not
affected and remain valid. With the firmware version ≥ 3.00.00.R, the inverter fulfills the
European grid-connection requirements in accordance with Regulation (EU) 2016/631 for
establishing a network code (also known as RfG), valid from April 26, 2019 within the EU.
For inverters with a firmware version ≥ 3.00.00.R: Save the parameter
settings before replacing the H-AC-CON
To ensure that the required parameter settings can be restored after replacing the assembly,
the parameter settings of the inverter must be read out and saved using a communication
product or be available in suitable form before removing the H-AC-CON. Since the
replacement of the H-AC-CON can only be completed with the associated parameter settings
and internal updates, it is necessary that the local conditions for the grid feed-in of the inverter
be in place.
Disconnecting the Inverter from Voltage Sources
1. Disconnect the circuit breaker from all 3 line conductors and secure against reconnection.
2. If the multifunction relay is used, switch off any supply voltage to the load.
