   2. Hex-head bolts (1/4 inch)

3. Use 2 hex-head bolts (1/4 inch) to connect the red and black battery cables to the bus bars that you installed in the previous step (Figure 4).

   Important: Loosely install the hex-head bolts to the cables and bus bars. You will torque the bolts in a later step.

4. Verify that the bus bars are seated properly and torque the hex-head bolts (Figure 3 and Figure 4) to 11 N·m (95 in-lb).

5. Route the battery cables toward the rear battery tray as shown in Figure 4 and Figure 5.

   Important: Ensure that the cables are routed away from pinch points or sharp edges.

6. Use 2 carriage bolts (1/4 inch), washers (1/4 inch), and 2 locknuts to connect the red and black battery cables to the bus bars at the rear battery tray as shown in Figure 6.

   Torque the hardware to 10.8 N·m (8 ft-lb).

   Note: The black battery cable in the kit is installed on top of the existing black battery cable on the machine as shown in Figure 6.

1. Connect the wire harnesses to the batteries as shown in Figure 7.

   

   Figure 7

   1. Wire harness (data interface—7-1/2 inches)
   2. Wire harness (data interface—45-1/2 inches)

2. Route the remaining connector of the data-interface wire harness (45-1/2 inches) toward the rear battery tray (Figure 7).

3. Remove the existing wire harness (CAN Terminator) from the D2 battery port (Figure 8). Retain the wire harness.

   Note: The CAN Terminator harness is a jumper that terminates the Controller Area Network (CAN) communication system to which the batteries are connected. When new batteries are installed, ensure that the terminator harness is installed to the newly installed batteries at the end of the network.

4. Install the remaining connector of the data-interface wire harness to the D2 battery port (Figure 8).

5. Install the wire harness (CAN Terminator) that you removed in step 3 to the D2 battery port on the top battery in the battery tray (Figure 9).

Important: Before you install the cable ties, ensure that the wire harness and cables are routed away from any moving or sharp parts.

Use 2 cable ties to secure the wire harness and battery cables together in the areas shown in Figure 13.

You must use Toro DIAG to configure the number of equipped batteries on the machine and verify their software revision level.

1. Turn the battery-disconnect switch to the OFF position.

2. Remove the charger-cable cover (Figure 14).

Note: This section only applies to an e3300 machine and a model year 2027 and newer e3200 machine.For an older e3200 machine, use the diagnostic port in the arm rest.The battery bus bars will have live voltage when the software is being updated.

1. Connect Toro DIAG to the machine; refer to the Toro DIAG Commercial Product User’s Guide.

2. Ensure that the software revision level for the batteries is updated by selecting the REPROGRAM button in Toro DIAG; refer to the Toro DIAG Software User’s Guide.

3. Lift the hood up to access the diagnostic port behind the seat.

4. Check and ensure the battery disconnect switch is OFF.

5. Update the battery software only using the diagnostic port behind the seat.

   Note: Ensure that the battery-disconnect switch is OFF while updating the battery software. All other machine controllers will not connect to ToroDiag during this time.

Figure 16

1. Turn the battery-disconnect switch to the ON position.

2. Connect to Toro DIAG using the diagnostic port.

3. Within Toro DIAG, select PRIMARY CONTROLLER, navigate to the CONFIG tab, then enter the number of batteries that are equipped on the machine in the NUMBER OF BATTERY PACKS field.

4. Disconnect Toro DIAG from the machine.

   

   Figure 17

1. Turn the battery-disconnect switch to the OFF position.

2. Install the DC power connector to the charger (Figure 15).

3. Install the charger-cable cover (Figure 14).

4. Turn the battery-disconnect switch to the ON position.

5. Charge the batteries; refer to your machine Operator’s Manual.

   Note: Ensure that the new batteries are fully charged to sync up with the charge level of the existing machine batteries. This enables the batteries to connect to the machine system.

6. Perform the following steps to verify the number of active batteries on the machine:

   1. Use the machine display screen to navigate to the DIAGNOSTICS menu.

   2. Navigate to the BATTERY menu item, select OUTPUTS, then scroll to the PACKS READY line.

   3. Verify that the number shown on the PACKS READY line matches the number of batteries that are equipped on the machine.
