Safety information

Warning
A hazardous voltage will be present in the component for a further 5 minutes after the
system has been shutdown. Work cannot be carried out until this time has elapsed.
Before starting work, you should also measure the voltage after the 5 minutes have elapsed!
The voltage can be measured on DC link terminals DCP and DCN.
Caution
The DC link discharge time hazard warning must be affixed to the component in the local
language.
Notice
The clearances above, below, and in front of the component, which are specified in the
dimension drawings, must be observed.
Caution
The busbars and coolant connections which stick out of the module must never be used as
handles or support surfaces when the units are transported.
Danger
Basic Line Modules discharge a high leakage current to the protective ground conductor.
Due to the high leakage current associated with Basic Line 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.
