Warning / Danger of electric shock
!
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 upon proper transport,
storage and installation. Before installation or maintenance work is carried out, the main 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.
Important Note: Input 3 phase circuit breaker is required! (Refer to "Input Data")
Caution
The device may only be opened by qualified personnel. Electrostatically sensitive devices (ESD)
Description and construction
The SITOP 48V/10A power supply are built-in units. The relevant local regulations must be observed during installation.
Primary switched-mode power supplies for connection to a 400-500 V, 50/60 Hz three-phase AC system (TN-, TT- or IT-system acc. to
VDE 0100 T 300 / IEC 364-3); output voltage +48 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 convection, the device must be installed vertically, with the input
and the output terminals at the bottom. Be sure to leave a minimum clearance of 50 mm above and below the device. The supply voltage (3-
ph. AC 400-500 V) must be connected in accordance with IEC 60364 and EN
above (miniature circuit-breaker or 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.
