2Device Installation
Dimensions
Installation Requirements
2.1
You need to purchase the mounting bracket separately from the Company.
•Moving an inverter requires four persons or appropriate transporting tools.
•Use lifting handles to facilitate installation, which are optional and delivered separately.
Ensure that the lifting handles are securely installed. After the installation is complete,
remove the lifting handles and keep them properly.
Moving an Inverter
2.2
Inverter + Mounting bracket
Inverter: < 99 kg
Mounting bracket: 6.09 kg
Manual Handling
The device can be moved manually or using a crane. If the installation position is high and the
inverter cannot be directly installed on the mounting bracket, you can use a crane to hoist and
move the inverter.

1. Take the inverter out of the packing case and move it to the specified position.
Hoisting
•To prevent damage to the device surfaces, do not use metal lifting ropes such as steel
ropes.
•Slowly and steadily hoist, move, and position the inverter to avoid bumping and damaging
the device enclosure.

Take the device out of the packing case, route the lifting ropes (with adequate load capacity to
support the device) through the two lifting eyes, and hoist the device to the installation
position.

Installing an Inverter
2.3
Installation Angle Installation Clearance
600–730 mm of clearance is
recommended underneath.
If the length of the M12X40 bolts delivered with the device does not meet the installation
requirements, prepare M12 bolts and use them together with the delivered M12 nuts.
Support-mounting
1. Install the mounting bracket to the support.

6
2. Install mounting ears.
3. Mount the device to the mounting bracket. If the device is moved manually, adjust the
positions of lifting handles at the bottom of the device. Tighten the two screws at the bottom
of the device.
Preparing Cables
3.1
3Electrical Connections
•Do not connect loads between the inverter and the AC switch that directly connects to the
inverter. Otherwise, the switch may trip by mistake.
•If an AC switch is used with specifications beyond local standards, regulations, or Huawei's
recommendations, the switch may fail to turn off in a timely manner in case of exceptions,
causing serious faults.

Note [1]: The value of the
conductor cross-sectional area is valid only if the conductors of the
ground cable and AC power cable are made of the same material. If the materials are different,
ensure that the conductor cross
-sectional area of the ground cable produces a conductance
equivalent to that of the area S/2. The specifications of the ground cable are subject to this table
or calculated according to IEC 60364
-5-54.
Note [2]: If the communication distances between the inverter and the Smart Array Controller
(SACU) and Smart Transformer Station (STS) are less than 100 m, FE communication is
recommended.
•The cable colors shown in cable connection schematic diagrams are for reference only.
Select cables according to local cable specifications.
•The factors that affect cable selection include the rated current, cable type, routing mode,
ambient temperature, and maximum expected line loss.
•To ensure that the inverter can be safely disconnected from the power grid when an
exception occurs, connect an AC switch to the AC side of the inverter. Select an
appropriate AC switch in accordance with local industry standards and regulations.
•Each inverter must be equipped with an AC output switch. Multiple inverters cannot
connect to the same AC output switch.

Opening Maintenance Compartment Doors
3.3
•Do not open the panel of the inverter.
•Before opening the maintenance compartment door of the inverter, turn off the external
switches on the AC and DC sides.
•Do not open the maintenance compartment door on rainy or snowy days. If you need to,
take protective measures to prevent rain or snow from entering the maintenance
compartment.
•Do not leave unused screws in the maintenance compartment.
The following describes how to open the maintenance compartment door on the DC side. The
procedure for opening the maintenance compartment door on the AC side is the same.
Connecting the Ground Cable
3.2
•It is recommended that the inverter
be connected to a nearby ground
point. The ground points of all
inverters in the same array must be
connected to ensure equipotential
connections to ground cables.
•The protective ground point on the
device enclosure must be connected
to a ground cable. The ground point
in the AC maintenance compartment
serves only as the equipotential
connection point of the protective
ground point and can be connected
based on site requirements.
