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 PSU8200 1ph 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 displays indicate the operating state. The operating state of the device can be processed via the signaling contact. The device can be switched ON/OFF remotely using a remote contact.

2.3Potentiometer
The potentiometer 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 24...28.8 V; for example, to compensate voltage drops across long supply lines to the connected load.
Figure 2-3 Potentiometer (example: 6EP3334-8SB00-0AY0)
NOTICE
Thermal overload possible
When adjusting the output voltage to >24 V, the output current must be derated by 4 %/V, or the permissible ambient temperature must be taken into account with 3° C/V.
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
Terminal data (Page 10).
