Wiring diagram, Low Voltage

Detailed LV connector C144 pin description C144.pdf

Connect the following pins:

• Pin 1 to 12V constant (BMS+)
• Pin 5 to 12V constant
• Pin 6 to 12V constant
• Pin 8 to 12V constant (Relay Control)
• Pin 25 to GND for 12V
• Pin 26 to GND for 12V
• Pin 15 or 21 to CAN-L on Battery-Emulator
• Pin 16 or 22 to CAN-H on Battery-Emulator

Note: The battery does NOT contain a terminating resistor, so it is a good idea to add a 120 Ohm resistor between CAN-L and CAN-H on the battery side.

Wiring, High voltage

High voltage interlocks

Jumpers need to be fitted on interlock detection pins, to make the battery believe the HV connectors are seated OK
