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.
Potentiometer R230 is only allowed to be actuated using an insulated screwdriver to DIN 7437, because accidental contact may
be made with parts inside the equipment carrying dangerous electrical voltage.
CAUTION
Electrostatically sensitive device (EGB). The device may only be opened by qualified personel.
Description and construction
The SITOP 24V/2A, 5A, 10A 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 mounting on a DIN EN 50022-35x15/7.5 standard.
For connection to 120 or 230V, 50/60Hz single-phase AC system.
Output voltage +24V DC, potential-free, protected against short-circuit and open-circuit conditions.

Installation
To ensure adequate cooling, the device must be installed vertically, with the input and output terminals at the bottom. Be sure to leave a minimum
free space of 50mm ( 2in.) above and below the device.
The supply voltage (AC 120/230V) and necessary jumper for the 120V range must be connected in accordance with VDE 0100 and VDE 0160. A
protective device (fuse) and an isolating device for disconnecting the power supply must be provided.
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.
If the equipment is operated in the 120V range, a jumper must be wired between the two "AC120V-JUMPER"-terminals. It must have the same
cross-section and insulation as the power supply cables. It must not be longer than 100mm ( 4in.).
Important: The necessary jumper also carries dangerous electrical voltage!
