2.4 SERVICE WARNING!
Do not service equipment with voltage applied! The unit can be the
source of fatal electrical shocks! To avoid shock hazard, disconnect
main power and control power before working on the unit. Warning
labels must be attached to terminals, enclosure and control panel to
meet local codes. Use Lock Out tags such as the one shown when
servicing equipment.
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 actual electrical shorts. After work is
complete, thoroughly clean, vacuum the area, and re-inspect the unit for
foreign material.
2.5.1 Clearances
Make sure there is sufficient clearance all around the unit for cooling,
wiring and maintenance purposes. To conserve panel space, the TE
Series –BP models were designed for close vertical clearances of only 1
inch (25mm) on either side. A minimum horizontal clearance of 4” (100
mm) on the top and bottom is necessary to maximize effective airflow
and cooling. Also 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.
