Installing a Backup Box

M6x60 expansion bolts are delivered with the Backup Box. If the length and number of the

bolts do not meet installation requirements, prepare M6 stainless steel expansion bolts by
yourself.
The expansion bolts delivered with the inverter are mainly used for solid concrete walls. For

other types of walls, prepare bolts by yourself and ensure that the wall meets the load
bearing requirements of the inverter.
In residential areas, do not install the inverter on drywalls or walls made of similar

materials which have a weak sound insulation performance because the noise generated by
the inverter is noticeable.
