Remove the fuse cover.

Install battery copper bars and power cables.
•
After removing the insulation cap from a
power cable, install the cable immediately
to prevent the exposed terminal from
touching the shell, which may cause
sparks or burns.
•
Check that there is no dirt on the surface
of copper bars to be connected to the
positive and negative terminals of battery
modules. If there is dirt, clean it up before
installing the copper bars.
•
Ensure that unused terminals and cables
are properly insulated. If an insulation cap
or insulation layer is damaged, repair it
promptly.
•
To avoid short circuit, do not insert tools
such as screwdriver directly into threaded
holes of positive or negative terminals of
the battery module.
•
When installing a copper bar, connect the part with a round hole to the
upper battery module, and connect the part with a slotted hole to the lower
battery module. Install the part with a round hole first, and then the part
with a slotted hole.
•
Excessive bolts will be used as spare parts.
a.
Open the terminal protective covers, install copper bars between battery
modules, and close the covers. Install copper bars between other battery
modules in sequence.

b.
Open the terminal protective covers, install copper bars between battery
modules and fuses, and close the terminal protective covers.

c.
Open the terminal protective covers, install the negative battery cables
reserved in the cabinet, and close the terminal protective covers.

After installing copper bars and cables, check that battery strings are insulated from
the cabinet.
Set a multimeter to the DC voltage mode and measure the voltage between the
uncoated part of the battery cabinet 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.
10
After checking that the battery strings are well insulated, reinstall the front covers
and fuse cover for the battery modules.
Before reinstalling the covers, check and arrange all cables of the board (the
cascading cable must be placed in the notch). Ensure that no cable is squeezed
by the covers.

Reinstall the BCU.
12
Use a marker to mark the corresponding models on the nameplate of the cabinet
based on the number of installed battery modules to facilitate future maintenance.
16 battery modules (example)
