2 GENERAL GUIDELINES
Alstom Grid IEDs are self-checking devices and will raise an alarm in the unlikely event of a failure. This is
why the commissioning tests are less extensive than those for non-numeric electronic devices or electro-
mechanical relays.
To commission the devices, you (the commissioning engineer) do not need to test every function. You need
only verify that the hardware is functioning correctly and that the application-specific software settings have
been applied. You can check the settings by extracting them using the settings application software, or by
means of the front panel interface (HMI panel).
The menu language is user-selectable, so you can change it for commissioning purposes if required.
Note:
Remember to restore the language setting to the customer’s preferred language on completion.
Caution:
Before carrying out any work on the equipment you should be familiar with
the contents of the Safety Section or Safety Guide SFTY/4LM as well as the
ratings on the equipment’s rating label.
Warning:
With the exception of the CT shorting contacts check, do not disassemble the
device during commissioning.
