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 “Environment” section;
• heat sink and internal fans freely rotating and dust free;
• the enclosure in which the drive is installed should be free from dust and condensation; furthermore ventilation
fans and air filters should be checked for correct air flow;
• checks on all electrical connections, ensuring screw terminals are correctly torqued; and that power cables have
no signs of heat damage.
