Selecting GVI mounting fasteners
Recommended bolts and washers for mounting of the motor controller are specified in chapter 10.5.1.
7.6
Wiring and connections
WARNING
High voltage - risk of personnel injury and/or damage to equipment
High power levels are exposed at each of the connection posts. These terminals should be
protected from accidental contact which could result in a short circuit.
This section provides schematic diagrams and related information for connecting the motor controllers in a
vehicle. These circuit diagrams present basic – but functional – general purpose wiring configurations. The
OEM may choose to modify these generic wiring configurations to fit their individual requirements or
conventions. It is the responsibility of the OEM to develop vehicle specific wiring schematics and instructions
for each vehicle mode.
7.6.1. Motor and battery connections
Recommended fasteners for the terminal posts are specified in chapter 10.6.
NOTE
The motor connections (U, V, and W) are not interchangeable and shall be connected to the
corresponding terminals on the motor.
CAUTION
Incorrect dimensioning of connections – risk of overheating
Ring lugs for motor and battery connections must be adequately rated to carry motor and
battery currents. Otherwise cables and terminal posts may be overheated. See also power
cable sizing guidelines in chapter 12.2.
An example of basic power wiring diagram for the motor controller and its motor is shown in Figure 10.
NOTE
Figure 10 is a simplified and generic schematic drawing. The actual wiring in a vehicle may
differ.
