Safety Information
1.1 Danger notices
Operating the equipment in the immediate vicinity (< 1.5 m) of mobile telephones with a
transmitting power of > 1 W may lead to incorrect functioning of the devices.
Connecting cables and signal lines should be installed so that inductive and capacitive
interference does not in any way impair the automation and safety functions.
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 devices EN 60204-1 (VDE 0113 Part 1) must remain active in all
modes of the automation equipment. Resetting the EMERGENCY STOP 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 devices)
