Grounding conductor test prior to recommissioning
Prior to recommissioning SMA inverters after the installation of SMA components or power
assemblies which cannot be replaced intuitively, ensure that the grounding conductor in the
inverter is correctly connected. The function of the grounding conductor must be ensured and
all locally applicable laws, standards and directives must be observed.
Observe superordinate standards
The repair work on devices and the consideration and application of other standards which

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.
Firmware update prior to disconnecting the inverter
To ensure trouble-free commissioning of the assembly, update the inverter firmware prior to
disconnecting the inverter.
• Prior to disconnecting the device from all voltage sources, check whether the firmware of
the inverter is up-to-date.
• If necessary, update the firmware.
Procedure:
1. Disconnect the AC miniature circuit breaker and secure against reconnection.
