Hi, a quick read of the OPERATING INSTRUCTIONS reveals that F0003 is an undervoltage Fault
Can you confirm that 415VAC is present on all supply phases, and that you have the correct DC Link voltage present (Approx Vin * 1.35)
Are you using a contactor inline with the supply, and is this being controlled correctly?
