Basic safety information
1.1. Safety instructions
Read and understand the instructions of this manual, and be familiar with
relevant safety symbols in this chapter, then start to install and troubleshoot the
equipment.
According to the national and state requir
ements, before connecting to the
electrical grid, you must get permission from the local electrical grid operation can
only be performed by qualified electrical engineer.
Please contact the nearest authorized service center if any maintenance or
repair is
needed.Contact your distributor for the information of the nearest
authorized service center. Do NOT repair it by yourself, it may cause injury or
property damage.
Before installing and maintaining the equipment, you should turn the DC
switch OFF to cut of
f the high voltage DC of the PV array. You can also turn the
switch in the PV combiner box OFF to cut off the high voltage DC.When the
battery needs to be installed, please confirm the positive and negative terminals of
the battery and turn OFF the battery.
Otherwise, serious injury may be caused.
