Legal information

Warning notice system

This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are graded according to the degree of danger.

DANGER

indicates that death or severe personal injury will result if proper precautions are not taken.

WARNING

indicates that death or severe personal injury may result if proper precautions are not taken.

CAUTION

indicates that minor personal injury can result if proper precautions are not taken.

NOTICE

indicates that property damage can result if proper precautions are not taken.

If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage.

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.

2.1Device description

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.

2.3 Potentiometer

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).

	feature is not available in this operating mode.
	Turning the power supply off for at least 60 seconds

	6EP3334-8SB00-0AY0).
	To also guarantee the upload of large capacitances at

	shutdown is performed during the first 10 seconds
	after power on or remote ON. During these first ten
	seconds, the device responds for overload as if the
	switch is OFF.

Function: The device is remotely switched off when contacts 15 – 16 are short-circuited (R < 8 kΩ). If the power supply is shut down and latched in the "latching shutdown" mode as a result of an overload, then it can be restarted using remote OFF followed by remote ON.
