The controller can be connected to the following loads:
•
resistive loads
The connected load must not exceed the maximum permissible values of the respective output (
Ò
Technical data).
u
Connect the GND of the load to GND
OVA
.
Do not connect GND of the load to other GND connections or to the common GND star point.
Deviating connections are not permitted.
