SINUMERIK 840Di Manual
To safeguard your own personal safety as well as protect the product described
and all connected equipment and machines against damage, please read and
observe the following warnings and safety information.
Operational electrical equipment has parts and components which are athazar-
dous voltage levels.
Allowing unqualified persons access to the equipment/system or failure to
heed the safety information could result in serious physical injury or substantial
property damage. Only properly qualified personnel who have been trained to
erect, install, start up or operate the product should be allowed to work on
Should it be necessary to test or take measurements on live equipment, then
the specifications and procedures defined in Accident Prevention Regulation-
VBG 4.0 must be adhered to, in particular § 8 "Permissible deviations when
working on live components". Suitable electric tools must be used.
Repairs to equipment supplied by Siemens must always be carried out by
SIEMENS after-sales service personnel or by repair centers authorized
by SIEMENS. Parts or components must always be replaced by parts or
components specified in the spare parts list.
Always disconnect the power supply before you open the unit.
EMERGENCY STOP devices in compliance with EN 60204 IEC 204 (VDE
0113) must remain operative in all operating modes of the automationde-
vice. Resetting the EMERGENCY STOP device must not result in any un-
controlled or undefined system restart.
Wherever faults in the automation device have the potential to cause sub-
stantial material damage or even human injury, i.e. they can present adan-
ger, additional external precautions must be taken or devices provided
which will guarantee or enforce a safe operating state in the event of a fault
(e.g. through independent limit value switches, mech. interlocks, etc.).
Connecting and signal leads must be installed such that inductive and ca-
pacitive interference cannot impair automation functions.
