Damage through use of incorrect DRIVE-CLiQ cables
Damage or malfunctions can occur on the devices or system when incorrect or unreleased
DRIVE-CLiQ cables are used.
• Only use suitable DRIVE-CLiQ cables that have been approved by Siemens for th
e
par
ticular application.
Note
Operation on line supplies where energy recovery is not possible
In line supply systems without energy recovery capability (e.g. a diesel generator),
device
faults can occur due to a lack of dissipation of braking energy.
Deactivate the energy recovery capability of the Smart Line Modules using the
corresponding parameter (see the SINAMICS S120/S150 List Manual).
The braking energy must then be dissipated via an additional Braking Module with
braking resistor in the drive line-up.
Note
Shutting down the device in the event of contaminated external heat sinks
For components with external air cooling, the fan and the heat sinks can accumulate a lot of
pollution. If the cooling air requirement is not provided by the filter fan, the components
cannot output their specified power. This can cause the temperature monitoring function in
the components to respond.
Check the fans and heat sinks for pollution at regular intervals and clean them when
necessary.
Note
For the S120 Combi Power Module 6SL3111
-4VE21-0EA0, a trip protection grid is provided
when it is shipped from the factory. For all other S120 Combi Power Modules, it can
be
ordered as replacement part and retrofitted.
