This equipment is intended for operation with low voltages, which are separated from
the AC 230 V (50 Hz) mains voltage – or voltages greater than AC 50 V or DC 120 V for
dry environments. A connection to an SELV circuit is recommended, or alternatively to
circuits with a different protective measure in accordance with IEC 60364-4-41 installation
standard.
5.5.2
