!
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.
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 mounting on standard rails as per DIN EN 50022-35x15/7.5.
For connection to a single-phase power supply. Rated voltages of 120V and 230V, 50/60Hz.
Output voltage +24V DC, electrically isolated, short-circuit proof and idling proof.

Installation
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 optional 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 optional jumper also carries dangerous electrical voltage!
