Communication Wiring to Gateway 3
Note
Refer to local codes and standards for
correct wiring practices and wire colors.
Terminal Name | Recommended Wire Color | Wire Gauge | |
---|---|---|---|
1 | CN- (CAN LO) | Orange | 24 - 16 AWG (0.2 - 1.5 mm2) |
2 | CN+ (CAN HI) | Blue | 24 - 16 AWG (0.2 - 1.5 mm2) |
3 | GND (Earth) | Black | 24 - 16 AWG (0.2 - 1.5 mm2)* |
4 | 12V+ (Logic+) | Red | 24 - 16 AWG (0.2 - 1.5 mm2)* |
* The recommended minimum wire gauge is 18 AWG (0.8 mm2) due to potential voltage drop on long wire runs with smaller conductors.
