3.11. Routine Maintenance
The drive should be included within the scheduled maintenance program so that the installation maintains a suitable operating
environment, this should include:
Ambient temperature is at or below that set out in the section
on page 65, with any relevant derating applied.
Heat sink fans (where fitted) freely rotating and are dust free.
If the drive is mounted within an enclosure:
o Ensure this is free from dust and condensation.
o Ensure sufficient ventilation of clean cooling air is provided.
o Ensure any panel ventilation fans and air filters are clean and provide the correct required air flow.
Checks should also be made on all electrical connections, ensuring screw terminals are correctly torqued; and that power cables
have no signs of heat damage.
