CAUTION
• To prevent a malfunction caused by noise, separate the signal cables more than 10cm from the power
cables.
• During wiring, do not leave wire off-cuts in the inverter.
Wire off-cuts will cause an alarm, failure or malfunction. Always keep the inverter clean. When drilling
mounting holes in a control box etc., take care not to allow chips and other foreign matter to enter the
inverter.
3-phase AC
power supply
Take care not to
short terminals
PC-SD.
Avoid frequent ON-OFF.
Repeated inrush currents at
power-on will shorten the
converter life.
(Switching life is 100,000)
