outputs
1)
Short, low-resistance connection from a case screw to the vehicle ground
2)
Separate ground connection to battery (chassis possible)
3)
Separate fuses recommended for switches and sensors and electronics
4)
CAN bus: 120 W termination resistor recommended (see installation instructions RDE 90 300-01)
5)
5V / ground outputs may also be used alternatively as sensor supply
6)
Observe maximum current consumption where proportional solenoids and switched outputs are controlled
simultaneously
7)
The terminals are labeled according to DIN 72 552. This does not apply for the controller.
