Front side and operating elements

L1, L2, L3

Mains input L1, L2, L3

PE input (protective conductor)

+

two identical positive poles, positive output

-

two identical negative poles, negative output

Potentiometer cover

Open the flap to adjust the output voltage. Factory setting: 24.1 V

Jumper for "Single Use"
or "Parallel Use"

Set the jumper to "Parallel Use" if devices are connected in parallel to increase the output power.
In order to distribute the load current among the individual power supply units, the "Parallel Use" mode regulates the output voltage so that the voltage at zero load is approx. 4% higher than at nominal load. A missing jumper corresponds to "Single Use" mode, which is the factory setting.

Push-in terminals
13 / 14

Monitors the output voltage of the active power supply.
