For power supply, use a circuit with energy limitation (EN/UL/
IEC 61010-1, section 9.3) with the following maximum values for
the current: with U = DC 30 V: 5 A / U = DC 35 V: 4.2 A. Provide a

separate switch for the external power supply. Alternative for North
America: The connection may also be made to „Class 2 Circuits" or
„Class 2 Power Units" according to CEC (Canadian Electrical Code)
or NEC (National Electrical Code).
