•
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.

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

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.)

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.
