2.6 Power Terminal Wire Range and Tightening Torque
Note: All wiring must be sized according to NEC standards.
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.
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 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.
