Holes for conduit, piping, etc., are normally
precut in module panels at the factory. However,
if it is necessary to change the location of a
hole or to cut a new one, these guidelines must
be observed:
•
Every hole represents a potential leak. Avoid
adding new holes to the enclosure if possible.
•
If it is necessary to add a new hole or to
move the location of a hole already in the unit,
select a location as close as possible to
hookup inside the enclosure.
•
Cut holes through panels.
DO NOT
cut through
structural members.
22) Removable panels are furnished for large items
such as coils. Adequate service space in front of
these panels should be provided in case the item
or items will have to be removed at some future
time (See
FIGURE 16
).
