8 Maintenance
8.1 Preventive maintenance operations
The MVX system does not require any specific operation for its maintenance, except
for dust cleaning on the ventilation inlets.
To do so, disconnect MVX from the power supply.
In case of a particularly dusty atmosphere, it can be useful to get rid of the dust
accumulated inside MVX.
To do so, please contact 01dB-Metravib’s after-sales department.
8.2 Replacement of the battery
The theoretical lifetime of the data back-up battery is several dozen years for a MVX
module under constant voltage.
Replacing this battery may however be necessary every 10 years.
Also, we recommend that the battery be replaced as soon as the MVX module has
remained totally unused for more than a year.
To replace the back-up battery, please contact the 01dB-Metravib’s support.
