Connection of the Power Unit
Depending on the case of application (e.g. no generatoric operation) simple circuits
can be used. See chapter 7 for instructions of the download. Input I1 must be program-
med and inverted in the application mode to "external error".
3.2.6 Final test informations of the machines/systems which are provided with frequency
inverters according to EN 60204 Part 1 of 2007
3.2.6.1 Voltage test (chapter 18.4)
Testing with 1000 Vac (or higher) may not be executed because it would destroy the
unit.
Permissible:
If a voltage test shall be done the inverter may be disconnected for this, since a voltage test
with 2180 Vdc according to EN 61800-5-1 is done ex factory.
3.2.6.2 Isolation resistance measurement (chapter 18.3)
An isolation resistance measurement is permissible, if all power unit connections (grid-con-
nected potential) and control connections are bridged each with PE (R > 2 MΩ).
