WARNING
!
Hazardous voltages are present in this electrical equipment during operation. Failure to properly maintain the equipment can
result in death, severe personal injury or substantial property damage. Only qualified personnel is allowed to work on or
around this equipment. The successful and safe operation of this equipment is dependent on proper handling, installation
and operation.
The mains switch has to be switched off and prevented from being switched on again before installation or maintenance. If
these rules are not adhered to, contact with live parts or improper use can result in death or severe personal injury.
CAUTION
Electrostatically sensitive device (EGB). The device may only be opened by qualified personel.
Description and construction
The SITOP 24V/0.5 and 0.375A power supplies are rail-mounted built-in units. The relevant DIN/VDE regulations or equivalent local
regulations must be observed during installation.
Primary switched-mode power supply for connection to 120-230V, 50/60Hz single-phase AC system (6EP1331-2BA10) respectively to 48-
220V DC system (6EP1731-2BA00); Output voltage +24V DC, potential-free, protected against short-circuit and open-circuit conditions.
