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.
SITOP PSU100L is a primary-clocked power supply for connection to a 1-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 is used to signal the operating state.
The end stop may be subject to a maximum load of 0.04
2.3 Potentiometer
The potentiometer ③ on the front of the device is used to set the output voltage. The output
voltage is set to 24 V in the factory, and can be adjusted in the range 22.8 - 26.4 V (for
6EP1336-1LB00 22.8 - 28 V); for example, to compensate voltage drops across long supply
lines to the connected load.
Figure 2-4 Potentiometer (example, 6EP1334-1LB00)
When adjusting the output voltage to greater than the rated voltage, the output current must
be derated by 4 %/V, or the permissible ambient temperature must be taken into account
with 3° C/V.

The selector switch as delivered (factory setting) is in the 230 V position. It must be moved to
the appropriate position for operation in the 120 V range. The selector switch can only be
actuated in the de-energized state.
