NOTE!
When contacting WEG for services, please have the following
data on hand:
Inverter model;
Serial number, manufacturing date and hardware revision,
as indicated on the inverter nameplate (refer to section 2.4);
Software version (refer to section 2.2);
Information about the application and inverter programming.
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!
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.
If this is necessary, contact WEG.
