Section 7 Checking installation
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
Do not insert anything else to the female connector but the
corresponding male connector. Inserting anything else (such as a
measurement probe) may damage the female connector and prevent a
proper electrical contact between the printed circuit board and the
external wiring connected to the screw terminal block.
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. Check that
there is no debris visible in the ventilation holes.
During IED start-up, you can observe the following sequence:
1. The Green Ready LED starts to flash.
2. The LCD lights up and
starting...
is displayed.
3. The main menu is displayed. A final steady green Ready LED indicates a
successful start-up of the device.
