Danger
Active Interface Modules discharge a high leakage current to the protective ground
conductor.
Due to the high leakage current associated with Active Interface Modules, they or the
relevant control cabinet must be permanently connected to PE.
Other than that the following measures must be taken in accordance with EN 61800-5-1:
Either protective ground conductor cross sections ≥ 10 mm² Cu or installation of a second
protective ground conductor of the same cross section as the first one.
Caution
The DC link discharge time hazard warning must be affixed to the component in the relevant
local language.
Notice
The cooling clearances above, below, and in front of the component, which are specified in
the dimension drawings, must be observed.
