SINUMERIK 810D Equipment Manual Configuration CCU (PHC) – 03/2006 Edition
Should it be necessary to test or take measurements on live equipment, then
the specifications and procedures defined in Accident Prevention Regulation of
the Berufsgenossenschaft BGV A3 (German employer’s liability insurance
association) must be adhered to, in particular § 8 “Permissible deviations when
working with live components”. Suitable electric tools should be used.
!
Danger
Operating electrical equipment has parts and components that are at
hazardous voltage levels.
After disconnecting all the supply voltages, a hazardous voltage will be present
in the DC link of all SIMODRIVE modules for another 5 minutes!
See Operating Guide
!
Danger
Repairs to devices that have been supplied by our company must 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.
Before opening the equipment, always ensure that the power is off.
EMERGENCY STOP devices complying with EN 60204 (VDE 0113 Part 1)
must remain effective in all automation equipment modes. Resetting the
EMERGENCY STOP device must not cause an uncontrolled or undefined
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. using an independent limit value switch,
mechanical interlocks etc.)
!
Warning
Connecting cables and signal cables should be installed so that inductive and
capacitive interference does not in any way impair the automation functions.
Warning
The modules contain electrostatically sensitive devices. Discharge yourself of
electrostatic energy before touching the components. The easiest way to do
this is to touch a conductive, grounded object immediately beforehand (for
example, the bare metal part of control cabinet or the protective ground contact
of a socket outlet).
