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.
Requirements to be met by external power supply
Input voltage range
DC 24 V ±10%
Rated input current
Max. 1.1 A
Peak inrush current
Typically: < 25 A
External fuse

Safety
Safety extra low voltage (SELV) according to EN 61800-5-1
CAUTION
!
The digital inputs and the DC 24 V terminal of the electronic control equipment can withstand external
voltage up to DC 30 V. Avoid higher voltage levels. Higher voltages may destroy the unit.
