Inspection
 Periodically inspect the
screws of the connection
between the operator
interface and device.
Tighten screws as
necessary as they may
loosen due to vibration
and varying
temperatures.
 Ensure that oil, water,
metallic particles or any
foreign objects do not fall
inside the operator
interface ventilation slots
and holes, as this may
cause damage to the
unit.
 Ensure the enclosure is
free from harmful dust,
gases, and liquids.
