3 Series/Parallel
Operation
3.1 Series Operation
¡
You can use a power supply in series operation. The output cur-
rent in series operation should be lower than the rated current of a
power supply with the lowest rated current among the power sup-
plies that are serially connected. Please make sure that no current
exceeding the rated current flows into a power supply.

3.2 Parallel Operation
¡
There is no current balance function.
When operating in parallel, such as diode-OR, please use on the
output voltage was adjusted enough to balance the current.
Exceeds the rated output current, the output is shut down.

Redundancy operation is available by wiring as shown below.

When you mount a power supply on a DIN rail, have the area
marked A catch one side of the rail and push the unit to the direc-
tion of B. To remove the power supply from the rail, either push
down the area marked C or insert a tool such as driver to the area
marked D and pull the unit apart from the rail.
When you couldn’t remove the unit easily, push down the area
marked C while lightly pushing the unit to the direction of E.
