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.
Before installation or maintenance work is carried out, the mains switch must be switched off and locked to prevent it from
being switched on again. 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 construction
The SITOP 24 V / 10 A, 20 A, 30 A and 40 A power supplies are built-in units. The relevant DIN/VDE regulations or equivalent local
regulations must be observed during installation.
Primary switched-mode power supplies for connection to a 400 V to 500 V, 50/60 Hz three-phase AC system; Output voltage +24 V DC,
potential-free, short-circuit resistant and stable under no-load conditions.

Installation
Mounting on a DIN EN 50022-35x15/7.5 standard rail. 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 (3-ph. AC 400 to 500V) must be connected in accordance with VDE 0100 and VDE 0160. It is important to provide the
protective device referred to above (circuit-breaker or motor circuit-breaker) and the disconnecting device for isolating the power supply. A
current-operated earth-leakage circuit-breaker must not be the sole device used where protection against indirect contact is required. The
same applies for the entire system protected by a current-operated earth-leakage circuit-breaker.
