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.

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, 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 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.
