Clearances
When mounting into an enclosure, make sure there is sufficient clearance all around the unit for cooling, wiring
and maintenance purposes. To conserve panel space, the
VMX Series
–BP models were designed for close
horizontal clearances of only 1 inch (25mm) on either side. A minimum vertical clearance of 4” (100 mm) on the
top and bottom is necessary to maximize effective airflow and cooling, and the unit must be installed with its
heat sink ribs oriented vertically and running parallel to the mounting surface. Keep in mind that these are
minimums. Wiring may require more clearance, particularly on the bottom.

Cleaning:
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
