Safety instructions for S120M
WARNING
Electric shock due to the residual charge of the DC link capacitors
Because of the DC link capacitors, a hazardous voltage is still present for a while after the
power supply has been switched off. In a drive line-up, this will be discharged within 5 minutes.
If you disconnect the S120M from the drive line-up, the high voltage can remain for 30 minutes
or longer.
Contact with live parts can result in death or serious injury.
● Only open the protective cover of the DC link and remove/insert the hybrid cable after this
time has elapsed.
● Before starting any work, also check that the system is in a voltage-free state by measuring
at the DC link terminals DCP and DCN.
● Do not remove the S120M from the drive line-up before the DC link is discharged.
WARNING
Electric shock due to high leakage currents caused by an interrupted external protective
conductor
The drive components conduct a high leakage current via the protective conductor. Touching
conductive parts when the protective conductor is interrupted can result in death or serious
injury.
● Ensure that the following protective conductor connection paths are available:
– Via the hybrid cable.
– Via the protective conductor connection. In this case, the protective conductor cross-
section must be ≥4 mm
2
.
Each of these connections must be suitable as a protective connection.
WARNING
Electric shock if an unapproved or damaged hybrid cable is used.
The use of an unapproved or damaged hybrid cable for connection to the Adapter Module can
lead to death or serious injury.
● For connection to the AM600 via interface X1, only use a suitable hybrid cable that has
been approved by Siemens for this application and is not damaged.
CAUTION
Fire hazard resulting from hot surface temperatures
During operation and for a short while after the equipment has been switched off, the surface
of the S120M is at a temperature which may cause burns if it is touched.
● Do not touch the S120M during operation.
● After switching off, you should also wait a few minutes until the S120M has cooled down.
