High–voltage test in the system
It is permissible to perform a high–voltage test on SIMODRIVE 611 drive con-
verters.
The components are designed/dimensioned in compliance with DIN EN 50178.
The following secondary conditions/limitations must be carefully observed when
the system is subject to a high–voltage test:
1. Power–down the unit.
2. Withdraw the overvoltage module in order to prevent the voltage limiting
responding.
3. Disconnect the line filter so that the test voltage does not dip.
4. Connect M600 to PE through resistor 100 k
Ω
(the grounding clip in the NE
modules is open). In the factory, the units are subject to a high–voltage test
at 2.25 kV
DC
phase–PE. The NE modules are shipped with the grounding
clip open.
5. The maximum permissible voltage for a high–voltage system test is
1.8 kV
DC
phase–PE.
If these points are not carefully observed, then the modules can be damaged
(preliminary damage).
