diameter (including the insulation layer). Remove sealing plugs only when necessary. Otherwise, the

sealing performance will be affected.

1. If the battery cabinet is installed but not powered on, manually powered off, or discharged, avoid

keeping it at low SOC for an extended period. Recharge the battery cabinet in a timely manner

according to the instructions in "Operations > Recharge Requirements for Batteries with Low SOC" in

the user manual. Otherwise, batteries may be damaged due to overdischarge.

2. It is recommended that an independent battery room be used. Before installing battery modules,

prepare fire extinguishing facilities, such as firefighting sands and liquid carbon dioxide fire

extinguishers, according to the construction regulations. Before operation, ensure that the battery room

is equipped with a fire extinguishing system that complies with local regulations.

1. Pull out the BCU.

-+PE

•Do not open the front cover of a battery module when installing or moving

it.

•Assign at least three persons or use a lifting trolley to move a battery

module. When using a lifting trolley to move a battery module on the

aisle, adjust the trolley angle to facilitate installation.

•Install the battery modules from bottom to top and from left to right to

prevent falling over due to imbalance.

•If half-capacity cabinet configuration is adopted, battery modules can be

installed only on the left side. Install a filler panel at the last but one layer

of the right column only after installing battery communications cables.

2. Install battery modules and filler panels.

3. Check the insulation performance of the battery

modules and secure the modules. (7+7 scenario

used as an example)

It is recommended that you use the DC voltage

mode of a multimeter to measure the voltage

between the ground point and the positive and

negative terminals of each battery module

respectively. If the readings are less than 6 V DC,

the insulation is good. Otherwise, contact

technical support engineers.

•Excessive bolts will be used as spare parts.

•When installing cables, ensure that the cables do not

block the QR code on the left of the protective cover.

5. Install battery copper bars and power cables. (7+7

scenario used as an example)

Round

7. After checking that the battery strings are well

insulated, close the front cover of each battery module.

6. Check the insulation between the battery

strings and the cabinet.

It is recommended that you use the DC voltage mode

of a multimeter to measure the voltage between the

battery tray and the positive and negative terminals of

each battery string respectively. If the readings are less

than 6 V DC, the insulation is good. Otherwise, contact

technical support engineers.

8. Attach PP sheets to the notches of the battery

modules on the top layer to prevent foreign

matter from falling into the cabinet. (7+7

scenario used as an example)

When attaching PP sheets, align them with

the edge of the front cover of battery

modules and ensure that the front cover can

be opened and closed properly after PP sheets

are attached.

9. Reinstall the BCU.

10.Select the corresponding model on the

nameplate of the cabinet based on the number of

installed battery modules. (The figure uses 14

battery modules as an example.)

05 Installing Battery Modules

•Do not open the protective covers for the positive

and negative terminals of a battery module at

the same time. Close the protective covers for the

terminals where copper bars have been installed.

•After removing the safety cap from a power

cable, install the cable immediately to prevent

the exposed terminal from touching the shell,

which may cause sparks or burns.

a. Open the protective covers for the negative terminal of

the battery module on the upper layer and the positive

terminal of the battery module on the lower layer.

b. Install copper bars between battery modules. Install the

copper bar end with a round hole at the battery

module on the upper layer, and close the terminal

protective cover. Install the copper bar end with a

slotted hole at the battery module on the lower layer,

and close the terminal protective cover.

c. Repeat these two steps.

d. Open the terminal protective covers, install the battery

power cables reserved in the cabinet, and close the

terminal protective covers.

SmartLi 3.0 Quick Guide (Short-Term Backup Power)

•If battery modules will be stored for a long time after power-off, remove the BCU to

reduce battery discharge. This prevents battery modules from being overdischarged due

to storage at low SOC.

•If battery modules are stored without being fully charged, charge them according to the

requirements in "Operations > Recharge Requirements for Batteries with Low SOC" to

prevent battery module damage due to overdischarge.

•When you hold the button to power off a cabinet, only the indicators on the cabinet

where the software version is later than V500R022C00SPC100 will blink.

The preceding procedure applies to the single-cabinet scenario. For the multi-cabinet

scenario, see
