7.4 PREVENTIVE
MAINTENANCE
DANGER!
Always disconnect the power supply voltage before touching any
component of the inverter.
Even after switching OFF the inverter, high voltages may be present.
Wait 10 minutes to allow complete discharge of the power capacitors.
Always connect the equipment frame to a suitable ground (PE) point.
ATTENTION!
Electronic boards have components sensitive to electrostatic
discharges.
Never touch the components or connectors directly. If this is
unavoidable, first touch the metallic frame or use a suitable ground
strap.
Never apply a high voltage test on the inverter!
If this is necessary, contact WEG.
To avoid operation problems caused by harsh ambient conditions,
such as high temperature, moisture, dirt, vibration or premature ageing
of the components, periodic inspections of the inverter and
installations are recommended.
