The depth of the holes should be about 30mm and should be the same. After removing the dust
in the holes, measure the net depth of the holes. If the depth is more than 33mm or less than
27mm, the expansion tubes wouldn’t be installed and tightened.
Expansion Screw
Expansion Pipe
Clean all dust outside/inside the hole and measure pitch-row before installation. It need
repositioning and drilling holes if the hole with much error. Then put expansion pipe into
the hole vertically, use rubber hammer to tap the pipe into the wall completely. After that,
twist 2 screws into 2 corresponding pipes, another 2 screws should be twisted into pipes
with gasket.
Use the bracket to install the inverter onto the narrow vertical panel (or wall). Put upper
-part holes of the inverter onto the bracket, lower part onto the M5 screw rivet of the
bracket (See figure 8).
