\*Note:

• If the battery module purchased excesses 10 sets (including 10), these battery modules should be installed in two towers, and the "Series Box" should be installed to connect two towers in series.
• If the battery module purchased is less than 9 sets (including 9), these battery modules may be installed in one or two towers. In case of two towers, the "Series Box" is recommended to install.
  ■ Additionally, the above accessories kit for "Series Box" needs to be purchased by customers themselves.

5 Equipment Installation

5.1 Installation Environment Requirements

■ Ensure that the equipment is installed in a well ventilated environment;
■ To prevent fire due to high temperature, ensure that the ventilation vents or heat dissipation system are not blocked when the equipment is running;
- Do not expose the equipment to flammable or explosive gas or smoke. Do not perform any operation on the equipment in such environments;
■ Ensure that the area is completely waterproof, and the floor is flat and level; and
■ Ensure that the temperature and humidity are maintained at a constant level, and there is minimal dust and dirt in the area.

5.2 Installation Procedure

\*Note:

1. Up to 9 battery modules can be installed in one tower. If the battery module users purchased excesses 10 sets (including 10), a Series Box needs to be installed to connect two towers in series.
2. The bearing capacity of the ground which is used to install the whole battery system must be over 500 kg/m ^2 .

Installation steps without Series Box

Take the installation procedure for four battery modules as an example.

Step 1. Take out Base, and adjust it.

The letters "R" and "F" on the Base indicate rear and front respectively. The side with "R" shall be against the wall.

Turn clockwise, lower the Base; Turn anti-clockwise, raise the Base. A spirit level is recommended to use.

Remove dust cover

Step 2. Locate Base, and accurately draw the location on both sides with a marker. A spirit level is recommended to use.

*Note: The distance between the Base and the wall can be about 20\~200 mm, but the recommended distance is 60 mm.

Step 3. Place one battery module on the Base.

*Note: If the Base is shifted after placing battery module, move it to its original location according to the mark previously drawn.

Step 4. Secure and tighten M4x20 Phillips-head screws ( × 4) on both sides (Torque: 0.9 to 1.1 N·m).

Installation steps with Series Box

In case of more than 10 sets of battery module (including 10), a Series Box needs to be installed to connect two towers in series, and an accessories kit for Series Box will not deliver for free.

The installation procedure for these two towers is the same as that for one tower. For details, please refer to the Step 1 to 8.

\*Note:

1. The rule for the sequence of battery modules in the whole system is as follows: In the case of one tower, the battery module closest to the BMS is numbered the first battery module, followed by the second battery module, the third battery module, according to the top-down principle. If another tower exists, the battery module closest to the "Series Box" can be continued numbering based on the tower with the BMS.
2. Regarding the cover plates on both sides of the BMS and the left side of the Series Box, they should be installed after finishing wiring.

6 Wiring

Current terminal connection and communication cable, connecting BMS and inverter, shall be made before conducting wiring.

6.1 Current Terminal Connection

The steps for making current terminal connection are shown as follows:

Step 1. Strip the cable jacket about 8 to 10 mm from the end;
Step 2. Cut the heat-shrink tubing to about 28 to 30 mm long, carefully slide it onto the end of the cable, and then carefully slip the wires all the way into the current terminal;
Step 3. Crimp the terminal, and heat the heat-shrink tubing after it wraps the end of terminal;
Step 4. Connect the assembled grounding cable to BMS, and then tighten the screw.

1) White with orange stripes
2) Orange
3) White with green stripes
4) Blue
5) White with blue strips
6) Green
7) White with brown stripes
8) Brown

The steps for making RJ45 connector to BMS communication cable are shown as follows:

Step 1. Strip the cable jacket about 15 mm down from the end;

Step 2. Carefully insert the wires all the way into the RJ45 connector, making sure that each wire passes through the appropriate guides inside the connector;

Step 3. Push the RJ45 inside the crimping tool and squeeze the crimper all the way down.

*Note: The BMS communication cable shall have a shield layer.

8 Troubleshooting

Check the indicators (refer to the "7.3 Status Indicators") to determine the status of T-BAT SYS-HV.

In case the following circumstance occurs, for instance, voltage or temperature exceeding the limit, a warning state will be triggered.

T-BAT system's BMS will periodically report its operating state to inverter.

In case the T-BAT SYS-HV exceeds the specific limit, it will enter a warning state.

And if the warning is reported, the inverter will stop working immediately.

Please use the monitoring software on the inverter to check the cause of warning.
