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 600 V or higher.
Note down the inverter settings before replacing the communication assembly
Prior to replacing the communication assembly, you must make a note of the specific settings and values of the
inverter, as they will not be automatically adopted after the replacement.
• Note down the following settings or values and reassign them to the inverter via a communication product
after replacement of the communication assembly: system time, system passwords, settings for the automatic
firmware update via the communication product and offset of the fed-in power (E-total).
• The following settings and values will be lost during replacement of the communication assembly and can nor
longer be transferred after replacement: event counter, event logger (event list with time stamp) and data
logger (daily yields and day yield curve).
