DANGER
Repairs to devices that have been supplied by our company may only be carried out by
SIEMENS customer service or by repair centers authorized by SIEMENS.
When replacing parts or components, only use those parts that are included in the spare
parts list.
EMERGENCY STOP/EMERGENCY OFF devices according to EN 60204-1 (VDE 0113
Part 1) must remain active in all modes of the automation equipment. Resetting the
EMERGENCY STOP/EMERGENCY OFF device must not cause an uncontrolled or
undefined restart.
Anywhere in the automation equipment where faults might cause physical injury or major
material damage, in other words, where faults could be dangerous, additional external
precautions must be taken, or facilities must be provided, that guarantee or enforce a safe
operational state, even when there is a fault (e.g. using an independent limit value switch,
mechanical locking mechanisms, EMERGENCY STOP/EMERGENCY OFF devices).
DANGER
External power supply units for supplying components of the drive control must have safety
isolation from circuits with dangerous voltages (DVC A according to EN 61800-5-1;
SELV/PELV). In addition only power units with control circuits that have safety isolation
from circuits with dangerous voltages may be connected.
