13 DIAGNOSTICS AND TROUBLESHOOTING
13.1 INFORMATION FOR CONTACTING TECHNICAL SUPPORT
✓
NOTE!
For technical support or servicing, it is important to have the following information at hand:
Inverter model.
Serial number, manufacturing date and hardware revision, which are available on the product identification label (refer to
Section 1.3 IDENTIFICATION LABEL OF THE MVW01 on page 1-2 ).
Software version (refer to Section 2.2 SOFTWARE VERSION on page 2-1 ).
Application and programming data.
For explanations, training or services, please, contact WEG Technical Assistance.
13.2 PREVENTIVE MAINTENANCE
DANGER!
Only people with properly qualified and familiar with the MVW01 Inverter and associated equipment must plan or service
this equipment.
Such personnel must follow the safety instructions described in this manual and/or defined by local standards.
The noncompliance with the safety instructions may result in death risks and/or damages to the equipment.
WEG Technical Assistance.
DANGER!
Seul un personnel formé, ayant les qualifications adéquates et familiarisé avec le the MVW01 et l’équipement associé
peut planifier et mettre en oeuvre l’installation, le démarrage, l’utilisation et la maintenance de cet équipement.
Ce personnel doit suivre toutes les instructions de sécurité décrites dans ce mode d’emploi et/ ou définies par la règle-
mentation locale.
Le non-respect de ces instructions de sécurité peut entraîner la mort, de graves blessures et/ou des dommages aux
équipements.

The MVW01 inverter has been designed and tested to have a long, failure-free, operation life. The preventive maintenance helps early iden-
tification of possible future failures, extending the useful life of the equipment, increasing the mean time between failures and reducing the
equipment downtime. It also helps identifying whether the equipment is being used within its mechanical, electrical and environmental limits.
The periodical cleaning during preventive maintenance assures an adequate operation when the inverter is used within its rated conditions.
In order to produce the best benefits, the preventive maintenance must be performed periodically by a qualified technician. The interval depends
on factors like the duty cycle and the environmental conditions (ambient temperature, ventilation, the existence of dust, etc.). It is recommended
to begin with the preventive maintenance frequently and increase the interval as the obtained results indicate the possibility of reducing that
frequency. A detailed record of the preventive maintenance is also recommended. These records serve as proof of the maintenance fulfillment
and help identify the cause of possible faults and alarms.
Two types of preventive maintenance are described next: during the inverter operation and with the inverter completely stopped/de-energized.
13.2.1 Preventive Maintenance During Operation
This type of maintenance is performed with the inverter energized and in operation. It is just necessary to access the control cabinet where
only low voltage power supply (< 480 V) is present, but which is potentially dangerous.
DANGER!
This equipment has high voltages that may cause electric shocks. Only people with properly qualified and familiar with
the MVW01 Inverter and associated equipment must plan or service this equipment. In order to avoid the risk of shock,
follow all the safety procedures required for servicing energized equipment.
Do not touch any electrical circuit before ensuring it is de-energized.
