•This quick guide describes how to install a solar
inverter on a support. For details about wall-mounted
installation, see the user manual.
•The M12x40 bolt assemblies are delivered with the
solar inverter. If the bolt assembly length does not
meet the installation requirements, prepare M12 bolt
assemblies by yourself and use them together with
the delivered M12 nuts.

Preparations
4.1
•Connect cables in accordance with the local installation laws and regulations.
•To prevent poor cable connection due to overstress, leave enough slack before connecting the
cables to the appropriate ports.

Installing a PE Cable
4.2
•It is recommended that the PE
cable of the solar inverter be
connected to a nearby ground
point. Connect the PE points
of all solar inverters in the
same array to ensure
equipotential connections to
PE cables.
•To enhance the corrosion
resistance of a ground
terminal, you are advised to
apply silica gel or paint on it
after connecting the PE cable.
Opening the Maintenance Compartment Door
4.3
•Do not open the panel of the solar inverter.
•Before opening the maintenance compartment door, turn off the downstream AC output switch
and three DC switches at the bottom.
•Do not open the maintenance compartment door in rainy or snowy days. If you have to, take
protective measures to prevent rain or snow from entering the maintenance compartment.
•Do not leave unused screws in the maintenance compartment.
1. Loosen the screws on the
maintenance compartment door. 2. Open the maintenance compartment door and adjust
the support bar.

4. Select a crimping module according to the type of the AC output power cable.
3. Remove the accessories and set them aside.

(Optional) Installing the Tracking System Power Cable
4.5
•The tracking system should be equipped with an overcurrent protective device or component.
The length of the cable between the power cable terminal and the overcurrent protection device
or component must be less than or equal to 2.5 m.
•The power supply of the tracking system should be an AC three-phase power grid.
•Keep inflammable materials away from the power cable.
•The power cable must be protected with a conduit to prevent short circuits caused by insulation
layer damage.
Removing the Rubber Rings from the Crimping Module
4.4
Use scissors to cut off the joints of the rubber rings to remove them. All rubber rings are removed in
the same way.
Remove the corresponding rubber rings strictly according to the cable diameter range, and ensure
that the crimping module is not damaged. Otherwise, the protection level of the solar inverter will
be affected.

Multi-core Connection Method
Installing the AC Output Power Cable
4.6
•This section describes how to install an AC output power cable for the 3-pin model.
•The cable outer diameter can be measured using the ruler sticker in the maintenance
compartment.
•Ensure that the AC output power cable is secured. Failure to do so may cause the solar inverter
to malfunction or damage to its terminal block by issues such as overheating.
•Sufficient slack should be provided in the PE cable to ensure that the last cable bearing the
force is the PE cable when the AC output power cable bears pulling force due to force majeure.
•If a screw on the maintenance compartment door is lost, obtain the spare screw from the fitting
bag tied at the bottom of the maintenance compartment.
