YASKAWA VS-616PS5 Series Programming Manual page 4

READ THIS ENTIRE MANUAL BEFORE INSTALLING OR OPERATING THE VS-616PS5!
The PS5 motor uses permanent magnets. HIGH VOLTAGE is generated by the
motor whenever the rotor is turning, with or without a power supply. Make sure
the motor is not turning before performing ANY service on the motor or on the
inverter.
If there is a possibility that the motor can be turned by the load while inverter
power is off, install a contactor or a manual disconnect to open the motor leads
while servicing the inverter. Interlock the disconnect with the control circuits of
the drive.
ONLY PERSONNEL WHO ARE EXPERIENCED IN WORKING WITH HIGH VOLTAGE, HIGH
POWER EQUIPMENT SHOULD INSTALL OR SERVICE THIS EQUIPMENT.
Turn off the supply power to the VS-616PS5 AND make sure the motor is stopped AND the internal
capacitors are discharged before connecting or disconnecting wires or touching any internal parts.
The VS-616PS5 internal capacitors remain charged even after the power supply is turned off. Wait
at least five minutes after removing power. Make sure all LED's are off before servicing the inverter.
Do not use a Megger or other type of high withstand voltage tester on the VS-616PS5. Higher volt-
Do not connect or disconnect the operator or a computer while the VS-616PS5 is running.
FAILURE TO OBSERVE THE WARNINGS AND PRECAUTIONS IN THIS MANUAL CAN EXPOSE THE USER TO HIGH
VOLTAGES, RESULTING IN DAMAGE TO EQUIPMENT, SERIOUS PERSONAL INJURY, OR EVEN DEATH.
The VS-616PS5 is suitable for use on a circuit capable of delivering not
more than 65,000 RMS symmetrical amperes at 480 VAC maximum (for
460 VAC class units) or 240 VAC maximum (for 230 VAC class units).
