  NOTICE  
1. Rated input voltage.
Input voltage range is set individually to our power supply. It is very dangerous if applied the voltage except the input range or applied the reverse voltage, which damages devices inside the power supply.
2. Leakage current.
Leakage current draws to all power supplies within the limited value. Though the individual value of leakage current is low, but when several units are operated as per below drawing, the total leakage current of the numbers connected will be drawn.
3. Wires
Wires are themselves have rated voltage and drawable current depend on the types. When wiring, please use thick wire which fits to rated output current.
4. Earth.
The earth terminal of power supply should be connected to the equipment where power supply is placed as thicker and shorter to protect electric shock or noise interference.
5. Fuse.
When the internal fuse is opened, it means devices inside the power supply is defected. Therefore, when fuse is opened, please ship unit back to us for repair.
6. High voltage.
There is a part of high voltage inside the power supply. Please do not touch by hand directly to avoid electric shock.
