Precautions
DANGER
Before connecting cables, ensure that all switches and breakers of the inverter
and the battery pack and all the switches connected to inverter and the battery
pack are set to OFF. Otherwise, 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 speci-fications
(green-and-yellow cables are only used for PE).
