Switch on the power supply only if the DIP switch is
positioned at a permitted setting.
Warning
Use power supplies which guarantee reliable electrical
isolation of the operating voltage as per IEC/DIN EN
60204-1. Consider also the general requirements for
PELV circuits in accordance with IEC/DIN EN 60204-1.
By the use of PELV circuits, protection against electric
shock (protection against direct and indirect contact) is
guaranteed in accordance with IEC/EN 60204-1 (Electri
cal equipment for machines, General requirements).
