side. Specication of the protective device should be at least 1.25 times the maximum AC
current.
• PE cable of the inverter must be connected rmly. The resistance between the neutral wire
and the earth cable is less than 10Ω.
• You are recommended to use copper cables as AC output cables. Contact the manufacturer
if you want to use other cables.
• When single overload protection occurs, the inverter can restart automatically; however,
the restarting time will be extended if it happens several times. For a faster restarting, try it
