2. Remove the end plate and disassemble the front module stack.

WARNING:

To prevent electric shock, wear insulated protective gear and use insulated tools.

ASSEMBLY

1. When replacing the Li-ion battery with a new battery, perform the following operation.
a. Enter the date of the (replacement) work on the EV battery tracking identification seal that is packaged

together with the new part.

b. Cut the EV battery tracking identification tool into 2 pieces and apply them to the body of the replaced

(old) LI-ion battery and to the “Li-ion battery replacement history record”.

c. Enter the necessary information in the “Li-ion battery replacement history record”.
2. Follow the procedure below to assemble the front module stack.

DANGER:

 There is the danger of electric shock caused by contact with the terminals. Be sure to wear

insulated protective gear and use insulated tools.

a. Assemble the module so that the module terminals are arranged as shown in the figure.

Be careful of the directions of the + terminal and – terminal when assembling the module. If

the polarity is incorrect, there is a risk of electric shock, fire, and component damage.

NOTE:

• To identify the module + terminal and 

− terminal, refer to the

figure.

• Install the module while aligning the position of the module col-

lar .

b. Install so that the end plate carabiner installation holes   are in the positions shown in the figure.

NOTE:

There are 2 end plates, each with different carabiner installation hole positions. If they are installed

reversed, the carabiner installation hole is positioned on the inside and lifting up is not possible.

c.

Install the mounting bolts   at opposite corners for each module, then insert 

φ7 mm (0.28 in) metal bars

(B) into the empty bolt holes and perform centering of the module collar position.

CAUTION:

If the collar position is incorrect, there is a risk of the bolts loosening because they are not sup-

ported by the collar between the modules.

d. Tighten the mounting bolt to the specified torque.
3. Follow the following procedure and install the bus bar module onto the front module stack.
a. Install the bus bar module  , then use an insulated torque driver to tighten the voltage detection terminal

mounting screws  .

DANGER:

•

 There is the danger of electric shock caused by contact with the terminals. Be sure to wear

insulated protective gear and use insulated tools.

•

This work must not be performed by multiple operators because there is a risk of electric

shock if the operators contact one another.

b. Tighten the module terminal mounting bolts in numerical order as shown in the figure.
