If the DC input power cable is reversely connected and DC switches are set to ON, do not
turn off the DC switches immediately or unplug positive and negative connectors. The device
may be damaged if you do not follow the instruction. The caused equipment damage is
beyond the warranty scope. Wait until the solar irradiance declines and the PV string current
reduces to below 0.5 A, and then turn off the two DC switches and remove the positive and
negative connectors. Correct the string polarity before reconnecting the string to the
SUN2000.
