1 SAFETY INSTRUCTIONS
This quick installation guide contains the basic information necessary to commission the MW500. It has
been written to be used by qualified personnel with suitable training or technical qualification for operating
this type of equipment. The personnel shall follow all the safety instructions described in this manual
defined by the local regulations. Failure to comply with the safety instructions may result in death, serious
injury, and/or equipment damage.
2 SAFETY WARNINGS IN THE MANUAL
NOTE!
It is not the intention of this guide to present all the possibilities for the application of the
MW500, as well as WEG cannot take any liability for the use of the MW500 which is not
based on this guide.
For further information about installation, full parameter list and recommendations, visit the
website www.weg.net.
DANGER!
The procedures recommended in this warning have the purpose of protecting the user
against death, serious injuries and/or considerable material damage.
ATTENTION!
The procedures recommended in this warning have the purpose of avoiding material damage.
NOTE!
The information mentioned in this warning is important for the proper understanding and
good operation of the product.
High voltages are present.
Components sensitive to electrostatic discharge.
Do not touch them.
Mandatory connection to the protective ground (PE).
Connection of the shield to the ground.
High temperature warning.
3 PRELIMINARY RECOMMENDATIONS
DANGER!
Always disconnect the general power supply before changing any electric component
associated to the inverter. Many components may remain loaded with high voltages and/ or
moving (fans), even after the AC power supply is disconnected or turned off. Wait for at least
ten minutes in order to guarantee the full discharge of the capacitors. Always connect the
grounding point of the inverter to the protection grounding.
NOTE!
Frequency Inverter may interfere with other electronic equipment. Follow the precautions
recommended in manual available in www.weg.net.
Do not perform any withstand voltage test!
If necessary, contact the manufacturer.
ATTENTION!
The electronic boards have components sensitive to electrostatic discharges. Do not touch
the components or connectors directly. If necessary, first touch the grounding point of the
inverter, which must be connected to the protection ground or use a proper grounding strap.
Do not touch the frame of the inverter directly. The inverter may be very hot during and
after the operation.
ATTENTION!
When the inverter is stored for a long period, it becomes necessary to perform the capacitor
reforming. Refer to the procedure recommended in www.weg.net.
