For applications outside these parameters, please consult us!
The amplifier card may only be unplugged and plugged when de-energized.
The distance to aerial lines, radios, and radar systems has to be at least 1 m.
Do not lay solenoid and signal lines near power cables.
For signal lines and solenoid conductors, we recommend using shielded cables.
The cable shield must be connected to the control cabinet extensively and as short as possible.
The valve solenoid must not be connected to free-wheeling diodes or other protection circuits.
The cable lengths and cross-sections specified in the technical data must be complied with.
Wiring information
Power zero b2 and control zero b12 or b14 or z28 must be separately led to the central ground (neutral point).
