10. MAINTENANCE
SD300 drives consist of advanced semiconductor devices. Temperature,
humidity, vibration and deteriorated components can reduce their efficiency.
To avoid any possible irregularities, we recommend making periodic
inspections.
Cooling
It is possible to replace the cooling fan without dismounting the whole
equipment. To do this, unscrew the screws and disconnect the connector.
The following image shows the standard fan usage rate. Replacement level
