4.2.2 External 24 V power supply X210A.1 & X210A.2
The bidirectional control terminals X210A.1/ X210A.2 can be used as a voltage output or voltage input. By
connecting an external power supply of DC 24 V ±10% to terminals X210A.1/X210A.2, the function of inputs and
outputs as well as the communication can be parameterized and maintained, even when mains voltage is off.

CAUTION
The digital inputs and the DC 24 V terminal of the electronic control equipment can withstand ex-
ternal voltage up to DC 30 V. Avoid higher voltage levels. Higher voltages may destroy the unit.
