Toshiba TE2 Series - Service Warnings and Mounting Clearances

TE2 Series Digital Solid State Soft Starter User Manual 6 | Page
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 Lockout 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 TE2
Series - BP models were designed for close clearances of only 1 inch
(25mm) on either side. A minimum clearance of 4 inches (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. NEC or local codes may require more
clearance, particularly for the power terminals.
