Extending The Exception List For Know-How Protection - Siemens SINAMICS G120 Operating Instructions Manual

7.6.1

Extending the exception list for know-how protection

In the factory setting, the exception list only includes the password for know-how protection.
Before activating know-how protection, you can additionally enter the adjustable parameters
in the exception list, which must still be able to be read and changed by end users – even if
know-how protection has been activated.
You do not need to change the exception list, if, with exception of the password, you do not
require additional adjustable parameters in the exception list.
Absolute know-how protection
If you remove password p7766 from the exception list, it is no longer possible to enter or change
the password for know-how protection.
You must reset the inverter to the factory settings in order to be able to gain access to the
inverter adjustable parameters. When restoring the factory settings, you lose what you have
configured in the inverter, and you must recommission the inverter.
