• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the inverter
and the interface card.
Otherwise, a fire or an accident might result.
• Incorrect handling in installation/removal jobs could cause a failure.
A failure might result.
Operation
• Be sure to mount the front cover before turning the power ON. Do not remove the cover when the inverter
power is ON.
Otherwise, an electric shock could occur.
• Do not operate switches with wet hands.
Doing so could cause an electric shock.
• If you configure the function codes wrongly or without completely understanding the FRENIC-VG Instruction
Manual and User's Manual, the motor may rotate with a torque or at a speed not permitted for the machine.
Confirm and adjust the setting of the function codes before running the inverter.
Otherwise, an accident could occur.
• When enabling the communications link (H30), be sure to check that a run command entered via the T-Link or
digital input terminals is OFF beforehand. Enabling it with the run command being ON causes a sudden motor
start.
• When resetting an alarm, be sure to check that a run command entered via the T-Link is OFF beforehand.
Resetting it with the run command being ON causes a sudden motor start.
• If a communications error occurs when the inverter is controlled via the T-Link, it may cause the inverter to fail
to recognize a stop command via the T-Link. Make an emergency stop measure using
BX
("Coast to a top") or
STOP1
,
STOP2
,
STOP3
("Decelerate to stop") assigned to inverter digital input terminals.
• If "Communications error processing" (y02, y12) is set to "Continue to run" or "Retry and continue to run," the
inverter may automatically start running after recovery from errors.
Otherwise, an accident could occur.
Maintenance and inspection, and parts replacement
• Before proceeding to the maintenance/inspection jobs,
turn OFF the power and wait at least five minutes for
inverters of 22 kW or below, or at least ten minutes for those of 30 kW or above
. Make sure that the LED
monitor and charging lamp are turned OFF. Further, make sure, using a multimeter or a similar instrument, that
the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC or below).
Otherwise, an electric shock could occur.
• Maintenance, inspection, and parts replacement should be made only by qualified persons.
• Take off the watch, rings and other metallic objects before starting work.
• Use insulated tools.
• Never modify the interface card.
Otherwise, an electric shock or injuries could occur.
Disposal
• Treat the interface card as an industrial waste when disposing of it.
Otherwise injuries could occur.
Others
• Never modify the interface card.
Doing so could cause an electric shock or injuries.
