The auxiliary power wiring should have a minimum cross-sectional area of 1.0 mm
2
and a voltage
rating of 250 V. Branch circuit protection must be provided in the auxiliary power supply wiring to
the IED, and if necessary it must be possible to disconnect manually from the power supply. Fuse
or circuit breaker up to 6 A and 250 V should be close to the equipment.
Ensure that the IED is grounded before starting it.

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:
1. The Green Normal LED starts to flash.
2. The LCD lights up and starting... is displayed.
3. 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 ABB technical support.
