Warning
Residual hazardous voltage are still present even after all of the power supply
voltages have been disconnected. The voltages can be present for up to 30
min for the capacitor modules.
The voltage must be measured in order to ensure that there are no hazardous
voltages present (generator principle for rotating motors)
!
Warning
The rated current of the connected motor must match the rated drive converter
current, as otherwise motor feeder cable protection is not guaranteed. The
cross–section of the motor feeder cable must be dimensioned for the rated
drive converter current.
!
Warning
Before commissioning the 611D, the encoder cable must be checked to ensure
that it has no ground faults. If there is a ground fault, uncontrolled movement
could occur for pulling loads.
No longer occurs from: 6SN1118–0DV2V–0AA0 Version C.
Note
The following limitations must be observed when the system is subject to a
high voltage test:
1. Power down the equipment so that it is in a no–voltage condition.
2. Withdraw the overvoltage module to prevent the voltage limiting respon-
ding.
3. Disconnect the line filter to prevent dips in the test voltage.
4. Connect the potential M600–PE through a 100 kΩ resistor (open the
grounding bar in the NE modules). The units are subject in the factory to a
high–voltage test with voltages of 2.25 kV
DC
, phase–PE. The NE modules
are shipped with the grounding bar open.
5. The maximum permissible test voltage for a high–voltage test in the system
is 1.8 kV
DC
Phase–PE.
Note
The terminal blocks of the SIMODRIVE 611 modules are exclusively used to
electrically connect the particular module. If they are used for any other applica-
tion (e.g. as carrying handle), this can damage the module.
