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 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.
CAUTION
The device may only be opened by qualified personnel. Electrostatically sensitive devices (ESD)
Description and construction
The SITOP 24V/5A and 10A power supplies are built-in units. The devices must be installed in accordance with the relevant DIN/VDE
standards or national codes of practice.
Primary switched-mode power supplies for connection to 1-phase AC systems or to 2 phases of three-phase systems (TN, TT or IT systems
in accordance with VDE 0100 T 300 / IEC 364-3) with rated voltages 120 V / 230V , 50/60Hz or to a DC system in the 240V to 350VDC
range, output voltage +24V DC, floating, short-circuit-proof and stable at no load.

Installation instructions
Mount on standard DIN rail DIN EN 50022-35x15/7.5. To ensure proper cooling, the device must be mounted vertically such that the input
and output terminals are at the bottom. A clearance of 50 mm in each case must be left above and below the device.
The supply voltage connection must be made in accordance with VDE 0100 and VDE 0160. An interrupter must be provided for safe
disconnection of the power supply.
