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.
Inspection

Visually check to ensure
that there are no lose
screws, metal shavings,
and conductive or
flammable materials that
may fall into the operator
interface.
