WARNING!
Obey the safety instructions given in
cabinets and modules safety instructions (3AXD50000048633
If you ignore the safety instructions, injury or death, or damage to the
equipment can occur.
If you are not a qualified electrical professional, do not do installation
or maintenance work.

Stop the drive and do the steps in section
before you start the work.
2.
Remove the air baffle from the module bay.
3.
Reinstall the module into its bay.
4.
Switch on the power to the supply/rectifier unit.
5.

Functional safety components
The mission time of functional safety components is 20 years which equals the time
during which failure rates of electronic components remain constant. This applies to
the components of the standard Safe torque off circuit as well as any modules, relays
and, typically, any other components that are part of functional safety circuits.
The expiry of mission time terminates the certification and SIL/PL classification of
the safety function. The following options exist:
•
Renewal of the whole drive and all optional functional safety module(s) and
components.
•
Renewal of the components in the safety function circuit. In practice, this is
economical only with larger drives that have replaceable circuit boards and other
components such as relays.
Note that some of the components may already have been renewed earlier, restarting
their mission time. The remaining mission time of the whole circuit is however
determined by its oldest component.
Contact your local ABB service representative for more information.
