7.1

Identifying hardware and software version

The information of hardware and software versions of the IED are available on the label attached on the

case of the IED. There are also module labels that can be used to identify the different modules inside

the IED (such as input-output cards and so on).

7.2

Checking mounting

Check that all fixing screws are tight and that all cables are connected.

7.3

Checking the power supply

Check that the auxiliary supply voltage remains within the permissible input voltage range under all

operating conditions. Check that the polarity is correct before energizing the IED.

7.4

Energizing the IED

Before connecting the auxiliary power, check that the terminal strip is wired and placed correctly. Remove

the protective film from the top side of the unit.

During IED start-up, you can observe the following sequence:

The Green Normal LED starts to flash.

The LCD lights up and starting... is displayed.

The main menu is displayed. A final steady green Normal LED indicates a successful start-up of the

device.

If the self supervision of the IED detects a diagnostic error during the start-up process, the green Normal

LED flashes. Further information on the error may be visible on the local HMI under Main menu/

Diagnostics/IED status/General. Note down the displayed information as reference when contacting

Hitachi Energy technical support.
