Maintenance And Inspection - Omron VARISPEED V7 IP65 Guia De Inicio Rapido

• Never touch the heatsinks, which can be extremely hot.
Failure to observe this caution may result in harmful burns to the body.
• It is easy to change operation speed from low to high. Verify the safe working range of
the motor and machine before operation.
Failure to observe this caution may result in injury and machine damage.
• Install a holding brake separately if necessary.
Failure to observe this caution may result in injury.
• If using an Inverter with an elevator, take safety measures on the elevator to prevent the
elevator from dropping.
Failure to observe this caution may result in injury.
• Do not perform signal checks during operation.
The machine or the Inverter may be damaged.
• All the constants set in the Inverter have been preset at the factory. Do not change the
settings unnecessarily.
The Inverter may be damaged.

Maintenance and Inspection

• Never touch high-voltage terminals on the Inverter.
Failure to observe this warning may result in an electrical shock.
• Disconnect all power before performing maintenance or inspection, and then wait at
least one minute after the power supply is disconnected. Confirm that all indicators are
OFF before proceeding.
If the indicators are not OFF, the capacitors are still charged and can be dangerous.
• Do not perform withstand voltage test on any part of the Inverter.
The Inverter is an electronic device that uses semiconductors, and is thus vulnerable to
high voltage.
• Only authorized personnel should be permitted to perform maintenance, inspections, or
parts replacement.
(Remove all metal objects (watches, bracelets, etc.) before starting work.)
Failure to observe these warnings may result in an electric shock.
• The control PCB board employs CMOS ICs.
Do not touch the CMOS elements.
They are easily damaged by static electricity.
• Do not connect or disconnect wires, connectors, or the cooling fan while power is applied
to the circuit.
Failure to observe this caution may result in injury.
