WARNING
Correct handling of the devices
When operating electrical devices, it is inevitable that certain components will carry
dangerous voltages.
Therefore, failure to handle the units properly can result in death or serious physical injury
as well as extensive property damage.
Only appropriately qualified personnel may work on or in the vicinity of this equipment.
Perfect, safe, and reliable operation of this equipment is dependent on proper
transportation, storage, installation and mounting.
Before installation or maintenance work can begin, the system's main switch must be
switched off and measures taken to prevent it being switched on again.
If this instruction is not observed, touching live parts can result in death or serious injury.

2.1
Device description
SITOP PSU2600 3ph is a primary-clocked power supply for connection to a 3-phase AC line
supply. An electronically regulated DC voltage that can be set via a potentiometer is
available at the output of the device. The output of the device is isolated, no-load proof and
short-circuit proof. The LED display indicates the operating status. The operating state of the
device can be processed via the signaling contact. The floating (isolated) reset optocoupler
input is used to remotely switch off the 24 V output voltage.

2.3
Potentiometer
The potentiometer on the front of the device is used to adjust the output voltage. The output
voltage is set to Uout ratedin the factory, and can be changed – for instance to compensate
voltage drops along long power supply cables up to the load.
Figure 2-3 Potentiometer, signaling
NOTICE
Thermal overload possible
When adjusting the output voltage Uout rated, the output current must be derated by 4 %/V, or
the permissible ambient temperature must be taken into account with 3 °C/V. It is not
permissible that Prated is exceeded.
Note
It is only permissible to
use an insulated screwdriver when actuating the potentiometer.
For information on actuating the potentiometer (screwdriver, torque), see Figure 2-2

WARNING
Installing the device in a housing or a control cabinet
The SITOP PSU2600 3ph power supply is a built-
in device. It must be installed in a housing
or control cabinet, to which only qualified personnel have access.
The device can be mounted in a control cabinet on standard mounting rails (see Chapter
Mechanical system (Page 31))
Mounting
To mount the device, position it with the mounting rail guide at the upper edge of the
standard mounting rail and press down to lock it into place. If it is too difficult to snap them
into place, press slider at the same time, as described under "Removal".
Removal
To remove, press on the slider ⑦on the upper side of the device and remove it at the lower
edge of the standard mounting rail. Then you can remove the device from the upper edge of
the standard mounting rail.

4.1
Standard mounting position
The device is mounted on standard mounting rails. The device must be mounted vertically in
such a way that the input terminals and the output terminals are at the bottom to ensure
correct cooling.
A clearance of at least 50 mm should be maintained above and below the device (maximum
depth of the cable duct, 50 mm).
No space is required at the side.

4.2
Other mounting positions
For mounting positions that deviate from the standard mounting position, derating factors
(reduction of the output power or the permissible ambient temperature) must be observed in
accordance with the following diagrams.
Note
In the case of mounting positions that deviate from the standard mounting position, reduced
mechanical resistance of the devices against vibration and
shock must be expected.
Particularly when installing on a vertically fastened standard mounting rail, additional
measures may be required, e.g. to prevent the device from slipping on the rail.
