Precautions
DANGER
Before connecting cables, ensure that all switch and breaker of the inverter and the battery
pack and all the switches connected to inverter and the battery pack are set to OFF. Other-
wise, the high voltage of the product may result in electric shocks.
WARNING
The device damage caused by incorrect cable connections is not covered
under any warranty.
Only certified electricians are allowed to connect cables.
Operation personnel must wear proper PPE when connecting cables.
NOTICE
The cable colors shown in the electrical connection diagrams provided in this chapter are for
reference only. Select cables in accordance with local cable specifications (green-and-yellow
cables are only used for PE).
