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
correspond to a superordinate standard is the responsibility of the qualified person performing
the work. Unauthorized alterations will void guarantee and warranty claims and in most cases
terminate the operating license. SMA Solar Technology AG shall not be held liable for any
damage caused by such changes.
