the inverter. Keep enough space for heat-dissipation when there are a few
inverters to be installed, at least 1.0m for inverter.
2) Pay attention to human and inverter safety when moving the inverters.
3) Inverter must be placed vertically, not allowed to flat, tilt or inverted.
4) Follow the steps below to fix the inverter.
2.1Fix the rack on the metal holder. (standard: M10*35mm, nut and flat pad)

Drill hole can be reserved or drilled on site on the metal holder according to
,
the hole size of rack drill hole size should be Ø12mm, as precise as possible.

2.2 The installation rack is fixed on the wall. (optional:M10*60mm,expansion
bolt).

Fix the installation rack contained in the package on the wall horizontally,
drill hole according to rack, drilling tool adoptsØ14mm impact, depth should
be more than 70mm, position should be as accurate as possible.

Clear dust inside and outside the hole, insert an expansion pipe vertically
into the hole, use hammer to knock until it is in the hole entirely, then unscrew

3.2 AC Cable Connection

First remove the lower cover of the inverter with an L-type spanner(in
the accessory bag).

make the inverter output cable go through water proof sleeves of AC
output cover, 5 (or 4) cores cable are crimped on the terminal (in the
accessory bag) and heat shrinkable casing respectively for protection.


connect the 5 cores to inverter output terminals L1,L2,L3,N, and PE
separately(three-wise system do not have "N" wise), Use straight
screwdriver to tighten it. The AC output is three phase, mode of
connection should be L1/L2/L3+N+PE or L1/L2/L3+PE. Finally, lock the
lower cover.
The example below is four-wise system.
Note: while connecting, the switch of AC side must be open, otherwise
it will do harm to the human body; it should use professional crimping
tool while crimping terminal, make sure the crimping is well, and
ensure safety.
