WARNING
!
Hazardous voltages are present in this electrical equipment during operation.
Failure to properly maintain the equipment can 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 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, a jumper must be inserted between the two "Jump 120VAC" terminals. This jumper must have the same
cross section and insulation as the mains supply cable. It must not be longer than 100 mm.
Important: The optional jumper also carries hazardous voltage!
IMPORTANT
Only qualified personnel may open the device. Electrostatically sensitive components
Description and design
The SITOP 24V/ 40A power supplies is a chassis-mounted unit. The device must be installed in accordance with the relevant DIN/VDE standards or national
codes of practice. The 24V/40A PS can be operated on public low-voltage systems only with additional measures as specified within the scope of EN 61000-3-2.
The equipment is to be provided with fixed connecting leads.
Primary switched-mode power supply 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; 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) and the optional jumper for the 120V range 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.
