7.3 PREVENTIVE MAINTENANCE
DANGER!
Only people with properly qualified and familiar with the MVW3000 Inverter and associated equip-
ment 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.

The MVW3000 inverter has been designed and tested to have a long, failure-free, operation life. The preventive
maintenance helps early identification of possible future failures, extending the useful life of the equipment, increas-
ing 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 tempera-
ture, 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 com-
pletely stopped/de-energized.
7.3.1 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.
