PV modules generate electric energy when exposed to sunlight and can create an
electrical shock hazard. Therefore, when connecting DC input power cables, cover PV
modules by using opaque cloth.
Before performing electrical connections, ensure that voltages of the DC cables should
be within the safe voltage range, that is, lower than 60 V DC, and the DC SWITCH is
OFF. Otherwise, the high voltage may result in fatal danger.
