2.5 Mounting and Cleaning

When drilling or punching holes in the enclosure, cover the electrical assembly
to prevent metal filings from becoming lodged in areas which can cause
clearance reduction or actually short out electronics. After work is complete,
thoroughly clean the area and reinspect the unit for foreign material. Make
sure there is sufficient clearance (six inches) all around the unit for cooling,
wiring and maintenance purposes. To maximize effective air flow and cooling,
the unit must be installed with its heat sink ribs oriented vertically and running
parallel to the mounting surface.
Remove all sources of power before cleaning the unit.
WARNING
In dirty or contaminated atmospheres the unit should be cleaned on a regular
basis to ensure proper cooling. Do not use any chemicals to clean the unit.
To remove surface dust use 80 to 100 psi, clean, dry compressed air only. A
three inch, high quality, dry paint brush is helpful to loosen up the dust prior
to using compressed air on the unit.
