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.
