When exposed to sunlight, the PV arrays supply DC voltage to the SUN2000.
Before connecting cables, ensure that the two DC switches on the SUN2000 are
OFF. Otherwise, the high voltage of the SUN2000 may result in electric shocks.
● It is recommended that the site be equipped with qualified fire extinguishing
facilities, such as firefighting sands and carbon dioxide fire extinguishers.
● Wear insulated gloves and use insulated tools to prevent electric shocks or
short circuits.
● The equipment damage caused by incorrect cable connections is beyond the
warranty scope.
● Only certified electrician can perform electrical terminations.
● Wear proper PPE at all time when terminating cables.
● To prevent poor cable connection due to overstress, it is recommended that the
cables be bent and reserved, and then connected to the appropriate ports.
