WARNING!
Remove all sources of power before cleaning the unit.
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 clean, dry compressed air
only, 80 to 100 psi. A three-inch, high quality, dry paintbrush is helpful to
loosen up the dust prior to using compressed air on the unit. Do not use
wire brushes or other conductive cleaning materials

Power Terminations
All line and load power terminations are to be made to the tin plated
copper Bus Tabs located on each unit. Bus tabs are pre-drilled to
accept industry standard bolts. Motortronics recommends using crimp-
on ring lugs, although mechanical compression lugs are suitable as
well. The following diagrams show sizes of the bus tab holes and critical
spacing between them for determining the size of lug that can be used.
Note: All wiring must be sized according to local and national code
standards.
