1)
Short, low-resistance connection from a housing screw to the unit or vehicle ground
2)
Separate ground connection from solenoid return lead to battery (chassis also possible)
3)
Separate fuses recommended for switches, sensors and electronics
4)
CAN bus: Terminating resistor 120 Ω recommended (see RDE 90 300-01 installation instructions)
5)
Separate ground connection from current source to battery, control unit GND (pin 38/49) possible
6)
Constant voltage source
7)
Observe max. current consumption where proportional solenoids and switch outputs are controlled simultaneously
