For Accusine SWP,what does mean the alarm message "Harm current > I nom" and what action to be taken?

This alarm message means that  The harmonic root mean square current absorbed by the load exceeds the AccuSine SWP nominal current making it operate in current limiting mode.
• The AccuSine SWP limits its compensating current to its nominal current rating (e.g. 30 A root mean square for a 30 A AccuSine SWP)
• The load is not entirely compensated
• The harmonic current difference (load harmonic I — compensating I) remains on Mains
• Problems may occur in your installation depending on the rate of harmonics remaining on Mains
• Consult Schneider Electric after-sales service
