• The M6x60 expansion bolts delivered with the battery are mainly used for solid concrete walls 
and concrete floors. If other types of walls and floors are used, ensure that the walls and floors 
meet the load-bearing requirements (one battery expansion module weighs 50 kg) and select 
the bolts by yourself.
• The power control module (DCDC) must be fixed on the wall. If the device is installed 
in an area prone to earthquakes or vibration, you can mark the battery module 
mounting holes and drill holes to install expansion bolts in step 2.
Keep a distance of 
10 mm to 15 mm 
between the support 
and the wall surface.
Align the 
marking-off 
template with the 
upper surface of 
the floor support.
