3.7.1 External 24 VDC voltage supply
The bidirectional control terminals X210A.1/X210A.2 can be used as voltage output or voltage input. If an exter-
nal 24 VDC voltage supply is connected to the terminals X210A.1/X210A.2 the parameterisation and communica-
tion is possible and input and outputs are active, even if the mains voltage is switched off.
The specification of technical requirements of the external voltage supply can be found in the operating instruc-
tions manual.
Requirements of the external voltage supply
Input voltage range 24 VDC ±10%
Input rated current Max. 1.1 A
Inrush current peak Typical: < 25 A
External fuse protection Via commercial available circuit breakers for rated current, charakteristic: slow-
acting
Safety Extra safety low voltage (SELV) according to EN 61800-5-1
