• Do not connect or disconnect wiring while the power supply is turned on.
• The internal capacitor remains charged even after the power supply is
turned OFF. Before servicing, disconnect all power to the drive to prevent
electric shock. Status indicator LEDs and Digital Operator display will be
extinguished when the DC bus voltage is below 50 VDC. Wait at least 1 minute
after the power supply is disconnected, and all indicators are OFF.
• Do not perform a withstand voltage test on any part of the unit. This electronic
equipment uses semiconductors and may be damaged by high voltage.
• Do not remove the digital operator or the blank cover unless the power supply is
turned OFF. Never touch a printed circuit boards (PCB) while the power supply is
turned ON.
• The drive is not suitable for circuits capable of delivering more than 18000 RMS
symmetrical amperes, 250V maximum (200V class units) or, 18000 RMS
symmetrical amperes, 480V maximum (400V class units).
