6.3.2 Install Drive Unit to Connection Interface
[Diagram showing the drive unit with numbered mounting holes (1, 2, 3) and an arrow indicating rotation. A second diagram shows the drive unit being attached to a frame interface with labeled bolts (A), washers (B), lock nuts (C), and a tool (D).]
Steps:
- Align Hole 1 on the frame interface with the mounting hole on the motor.
- Rotate the motor anticlockwise around Hole 1, and align Hole 2 and Hole 3.
- Fasten 3 M8 bolts into Holes 1, 2, 3 from the right side to the left side.
- Fasten the 3 M8 lock nuts with flat washers on the left of the frame, with tightening torque at 35 N.m.
6.3.3 Cabling
[Diagram showing the drive unit with various connectors labeled A, B, C, D and corresponding female connectors labeled a, b, c, d. A legend explains each connector type and its purpose, such as 'Male connector for power supply at the drive unit', 'Female connector for power supply at the battery', etc.]
Steps:
- Link the female connector (8 pin) for EB-BUS “d” to the male connector (8 pin) at the drive unit “D”.
- Link the male connector (8 pin) for EB-BUS “c” to the female connector (8 pin) at the drive unit “C”.
- Link the power connectors together.
Note: Whether to link the 6-pin EB-BUS to the drive unit depends on customer functional requirements.
