Switched outputs
1)
Short, low-resistance connection from a housing screw to the unit- or vehicle ground
2)
Separate ground connection from solenoid return line to the battery (chassis also possible)
3
) Separate fuses recommended for switches, sensors and electronics
4
) CAN bus: 120 Ω terminator recommended (see installation instructions RDE 90 300-01)
5
) Constant voltage source
6
) Observe maximum current consumption where proportional solenoids and switched outputs are controlled simultaneously
