*1.
Do not use an inverter output for the Power Supply. Inverters with an output frequency of 50/60 Hz are available, but the rise in the internal temperature of the Power Supply may result in ignition or burning.

*3.
If the output voltage adjuster (V. ADJ) is turned, the voltage will increase by more than +15% of the voltage adjustment range. When adjusting the output voltage, confirm
the actual output voltage from the Power Supply and be sure that the load is not damaged.

Safety Standards for a DC Input
The following safety standards apply to a DC input: UL 60950-1, cUR (CSA C22.2 No. 60950-1), EN 50178, EN 60950-1, and Lloyd’s.
For a DC input, safety is ensured by an external fuse.
Select an external fuse that meets the following conditions.
