Front side and operating elements

Input terminals (screw terminals)

Designation (A)	Description
+	positive input
-	negative input
	PE -> Protective Earth (Ground) connection

Output terminals (screw terminals)

Designation (B)	Description
+	positive output
-	negative output, two identical - poles

Output voltage potentiometer

Designation (C)	Description
Potentiometer	Adjust the output voltage, Factory setting: 24.1 V

DC-OK LED

Designation (D)	Description
LED green	DC-OK LED (green) On: voltage on the output terminals is > 21 V

DC-OK relay contact (screw terminals)

Designation (E)	Description
13 / 14	The DC-OK relay contact is synchronized with the DC-OK LED. See chapter DC-OK relay contact for more details

Link for parallel use (F), “Parallel Use” “Single Use” link

Designation (F)	Description
Push-in terminals	Connect the two terminals when power supplies are connected in parallel. In order to achieve a sharing of the load current between the individual devices, the “parallel use” regulates the output voltage in such a manner that the voltage at no load is approx. 4 % higher than at nominal load. (See chapter Parallel Use to Increase Output Power for details).

Description

Push-in terminals

Connect the two terminals when power supplies are connected in parallel.

In order to achieve a sharing of the load current between the individual devices, the “parallel use” regulates the output voltage in such a manner that the voltage at no load is approx. 4 % higher than at nominal load. (See chapter Parallel Use to Increase Output Power for details).
