module is, however, not protected against possible damage due to
overvoltage. This alarm serves to notice possible overvoltage situa-
tions coming from the source.

This error is a) either triggered if the remote Sense connectors are not correctly wired
or interrupted or b) if the difference between input voltage on the DC input and the
