2.3.2 Mounting

Remember that this inverter is heavy! Please be careful when lifting out from the package. 

The inverter is suitable for mounting on concrete or other non-combustible surfaces only.

Please use the mounting bracket as a template to drill 4 holes in the correct positions 
(10mm in diameter and 80mm in depth).
Use the expansion bolts in the accessory box and tightly attach the mounting bracket to the 
wall.

Carry the inverter by holding the heat sink on two sides and place the inverter on the 
mounting bracket.

FOR AUSTRALIA ONLY. Lock the DC switch before mounting. Make sure that the DC switch is 
locked unless the inverter is powered on.

Note: Bearing capacity of the wall must be higher than 30kg, otherwise it may not be able to 
keep the inverter from dropping.
