Technical Data - Siemens SITOP 5A Instrucciones

WARNING
! Hazardous voltages are present in this electrical equipment during operation.
Failure to handle the equipment properly can therefore result in death, severe personal injury or substantial property damage.
Only qualified personnel should work on or near this equipment.
The product will function correctly and safely only if it is properly transported, stored, set up and installed.
The main plant switch must be switched off and secured against reconnection prior to installation or maintenance of the equipment. Failure to
disconnect the main switch means that contact with live parts could result in death or severe personal injury.
To operate the unit in 120V mode, the switch on the side panel under the cover (see picture on page 3 for location) must be set to the 120V
position.
IMPORTANT
The unit may only be opened by properly trained personnel. Contains electrostatically sensitive components!
Description and design
The SITOP 24V/5A and 24V/10A power supplies are chassis-mounted units. The devices must be installed in accordance with the relevant DIN/VDE standards
or national codes of practice. The equipment is to be provided with fixed connecting leads.
Primary switched-mode power supplies for connection to 1-phase AC systems or to 2 phases of three-phase systems (TN, TT or IT (≤3AC 500V) systems in
accordance with VDE 0100 T 300 / IEC 364-3) with rated voltages 120-230V / 230V to 500V , 50/60Hz; 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 (AC 120V/230V) must be made in accordance with VDE 0100 and VDE 0160. A protective device (circuit-breaker) and
interrupter must be provided for safe disconnection of the power supply. If the power pack is operated between phases L1 and L2, and an r.c.d. is used as
protection against direct or indirect contact, then the r.c.d. must be a universal device (type B).
Parallel operation and selectable short-circuit behavior
Selector switch Function
A For load distribution in parallel operation, the devices can be switched from single mode (switch setting OFF) to parallel mode (switch
setting ON). Switch setting ON produces an inclined output characteristic
B In switch setting OFF (constant current mode), the device supplies a constant current of about 1.15 x rated current in the case of an
overload/short circuit. In switch setting ON (shutdown mode), the device is shut down if it is overloaded for more than about 100 ms. This
status can be reset by Power OFF for at least 5 seconds followed by Power ON.
