1.
Mount the PMAC II panel in a central loca-
tion such as a motor or electrical room. The
panel should be where there is good air flow
(not in a closet). Keep a 6-12 inch clearance
on top and bottom for good air flow. The
room's ambient temperature should always
be below 100° F. Figure 2-1 and Figure 2-2
have the mounting dimensions.
