2Installaon
2.1 Precauons for Installaon
Light intensity is required near the installaon locaon.
Comply with the safety operaon technical regulaons when liing and handling heavy objects.
Equipment and tools must be complete, intact, and reliable. It is strictly prohibited to use tools with
cracks, burrs, loose handles, etc., that do not meet the safety standards.
Installaon operaons must be guided by qualied engineers.
Duringinstallaon, two people must work together, one operag and the other inspecg.
The original cable connecon and operaon process shall not change without the authorizaon of
the company's consent.
2.2 Preparing for Installaon
2.2.1 Tools
Insulated installaon tools must be used to prevent electric shocks. If tools without insulaon protecon
are used, the exposed metal parts must be wrapped and insulated with insulag tape.
The following table shows tools that need to be prepared before installaon.

Context
1 Insulate installaon tools to prevent electric shocks.
2According to the power value of the inverter, the power cable should be connected. If mulple beries are used in
parallel, the power cables should be connected according to the wiring mode in Figure 9.
The VT-48280-W2 power cable connecon method adopts a self- locking connector. The descripon of
the self-locking connector is shown as follows:
The steps for connecg the self-locking connector are as follows:
A Adjust the direcon of the self-locking connector to align with the VT-48280-W2 terminal.
B Rotate the self-locking connector slightly, and it will be inserted automacally.
C Aer the self-locking connector is automacallyinserted, push it in slightly, and aer hearing a
click sound, the self-locking connector and the baery module terminal are connected.
Need to press the buons on the self-locking connector simultaneously when users need to pull
out the self-locking connector.
Figure 8. Self-locking connector buon
If there are muleVT-48280-W2 in parallel, you need to connect them in parallel using the parallel power
cables, then connect the power cable to the inverter. Please pay aenon to the dison between
baery modules’ posive and negave terminals.
Procedure
1Connect the internal power cables of VT-48280-W2
14

Figure 9. Connect the internal cables
2Connect the P+ & P- power cables to the inverter.
Figure 10. Connect the external cables
The self-locking connector's color should correspond to the VT-48280-W2 terminal's color: orange corresponds to
the posive pole, and black corresponds to the negave pole.
Please take care of the removed VT-48280-W2 protecve cover in case of backup.

2.5 Connecng Communicaon Cable
Context
Please pay enon to the direcon when plugging the communicaon cable connector, do not operate violently.
Communicaon cables and power cables must be routed separately.
If there are muleVT-48280-W2 in parallel, you need to connect the communicaon cables in parallel
rst. Then you need to connect the communicaon cable of the inverter to COM1 of any VT-48280-W2
Procedure
1Connect the internal communicaon cables of the VT-48280-W2
Figure 11. Connect the internal cables
2Connect the remaining power cables and communicaon cables between the VT-48280-W2 and
inverter.
Figure 12. Connect the external cables

3For the wiringdiagram of the inverter to the user side, please refer to the user manual of inverter.
Please conrm the usage scenarios of the inverter according to the actual situaon. For details, please refer to the
user manual of inverter.
The communicaon cable to the inverter contains L&N cable (220V power supply for BMS). Please connect this cable
to the output port of the inverter. (Oponal)
Recommended open-circuit current from the bery to the inverter: rated operang current 250A, rated operang
voltage DC110V, rated short circuit breaking capacity 25kA (DC110V). If the inverter has instrucons, the inverter
shall prevail.
