• Make sure that the load connection wires are of the same length and thickness so that the same
current flows through the wires.
 Overvoltage Protection
When an excessive voltage that is approximately 130% of the rated output voltage or more is output, the
output voltage is cut OFF, preventing the load from damage due to overvoltage.
To reset the Power Supply, turn off the input power for at least 3 minutes and then turn it on again.
Note: Do not turn ON the power again until the cause of the overvoltage has been removed.
 Parallel Operation
Set the switch to "PARALLEL" if the units are in parallel operation.
SINGLE : The output current can use 100% of the rated output current.
PARALLEL : Overcurrent protection limits the output current to 80% of the rated output current.
 In Case of No Output Signal
The overcurrent or overvoltage protection may be functioning. If a large surge voltage such as a lightning
surge is applied to the input, the internal protection circuit may be functioning. Please contact us if there is
still no output voltage even after checking the following two points.
• Checking the overcurrent protection
Check (by removing the load cable) whether the load is in an overcurrent state (including short circuit).
Turn off the input power once, leave it for at least 3 minutes, and then turn on the input power again.
• Checking both the overvoltage protection and internal protection
Turn off the input power once, leave it for at least 3 minutes, and then turn on the input power again.
