WARNING
!
Hazardous voltages are present in certain parts of this electrical equipment during operation. Incorrect handling of the
equipment can result in death, severe personal injury or substantial property damage. Only qualified personnel are allowed
to work on or around this equipment. The successful and safe operation of this equipment is dependent on proper transport,
storage and installation.
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
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
The device may only be opened by qualified personnel.
Electrostatically sensitive devices (ESD)
Description and Design
The SITOP 24V/ 20A power supply is a device of the built-in type. The pertinent DIN/VDE standards or country-specific specifications apply
to the installation of the device.
Power supplies with primary AC input for connection to 120 or 230V, 50/60 Hz single-phase AC system. Output voltage +24V DC,
potentialfree, protected against short-circuit and open-circuit conditions.

Installation
Mounting on standard rails as per DIN EN 50022-35x15/7.5.To ensure adequate cooling, the device must be installed vertically so that the
input terminals are at the top and the output terminals at the bottom. Be sure to leave a minimum clearance of 50 mm above and below
and 40mm to the left of 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. 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.).
!
WARNING: The necessary jumper for operating voltage range 93-132V also carries dangerous electrical voltage!
