Electronics Enclosure Flamepaths (Joining Surfaces)
Any time the Electronics Enclosure is opened for maintenance, inspect the
amepath (joining surfaces) for scratches, indentations, or other damage.
Carefully clean the amepath with a soft, non-abrasive cloth just prior to clos-
ing it.
If it is necessary to use a cleaning agent, make sure the AC power to
the analyzer is o. Also, the agent must be non-abrasive and must
not attack aluminum (example, a suitable agent is Isopropanol).
Following any maintenance and/or cleaning – and after the cleaning
uid has evaporated completely – immediately close the Electronics
Enclosure.
When the Electronics Enclosure is opened for maintenance or repair,
take extreme care to avoid scratching or damaging its amepaths.
Always close the enclosure door and secure it with one screw when-
ever service or maintenance is not being performed on the internal
components of the Electronics Enclosure. This will reduce the risk of
inadvertently scratching or damaging the amepath.
Before closing the door, gently clean the amepath (joining surfaces)
with a soft, non-abrasive cloth and make sure the surfaces are free of
debris.
When performing equipment maintenance in hazardous locations, all
safety standards and procedures must be followed, as specied by the
Owner Company, local electrical-inspection authority, and National/
EU regulations.
