SINUMERIK 810D Manual Hardware Configuration (PHC) - - 11.02 Edition
Repairs to devices that have been supplied by our company must only be
carried out by SIEMENS Customer Service or by repair centers author-
ized by SIEMENS. When replacing parts or components, only use those
parts that are included in the spare parts list.
Before opening the device, always disconnect the power supply.
EMERGENCY STOP devices complying with EN 60204 IEC 204 (VDE
0113) must remain effective in all automation equipment modes. Resetting
the EMERGENCY STOP device must not cause an uncontrolled or unde-
fined restart.
Anywhere in the automation equipment where faults might cause major
material damage or even physical injury, 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. caused by an independent limit switch, mechani-
cal interlocks, etc.).
Connecting cables and signal lines should be installed so that inductive and
capacitive interference does not in any way impair the automation func-
tions.
