Figure 5-21 Connecting DC input power cables
If the DC input power cable is reversely connected and DC switches are set to ON,
do not immediately turn off the DC switches or reconnect the positive and
negative connectors. Otherwise, the device may be damaged. The caused device
damage is not covered under any warranty. Wait until the solar irradiance declines
at night and the PV string current reduces to below 0.5 A. Then, turn off the three
DC switches, remove the positive and negative connectors, and rectify the
connection of the DC input power cable.
