†
) The DH21A existists in two different hardware variants:
– Function outputs AUX3, AUX4: each 1,0 A
(connecting option -0/-2/-3/-4)
– Function outputs AUX3, AUX4: unamplified *)
(connecting option -5)
If necessary: Connect blue wire (common return conductor) to VS.
You can connect a buffer capacitor to ZVS (+) and GND (-).
