Warnings for UL/cUL Marking
•Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON.
•The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent
electrical shock, disconnect all power before servicing the Inverter. Then wait at least one minute after
the power supply is disconnected and all indicators are OFF.
•Do not perform a withstand voltage test on any part of the Inverter. This electronic equipment uses
semiconductors and is vulnerable to high voltage.
•Do not remove the Digital Operator or the blank cover unless the power supply is turned OFF. Never
touch the printed control board (PCB) while the power supply is turned ON.
•The Inverter is not suitable for use on a circuit capable of delivering more than 5,000 RMS symmetrical
amperes, 250 volts maximum (200-V-class Units) or 18,000 RMS symmetrical amperes, 480 V maxi-
mum (400-V-class Units).
•Take measures against overcurrent, overload, and overheating by using the Motor Protection Set-
tings.
