Power Structure Installation
Preparing the Enclosure
Frames 10…12
To facilitate ease of service, it is recommended that the power structure be
mounted on support rails. Fasten the rails to the sides of the enclosure at
distances “F” (from the top) and “G” (from the bottom) shown in
Figure 11
(below). Leave a space (“A”) between the structure and side walls for internal
cooling air flow. When two enclosures are utilized for a Frame 12 installation,
space between the enclosures is not required.
The power structure should be secured to the rear of the enclosure as shown by
installing two rails on the rear wall of the enclosure at the appropriate levels.
Refer to the dimension drawings in Component Dimensions beginning on page
53
for more details.

(1) Dimension if the AC choke is installed at the bottom of the enclosure. If the choke is installed in another location, the distance must
be greater than 290 mm (11.4 in.).
E
(2)
(2) Minimum distance from the enclosure door. This allows installation of the control frame in front of the power structure. If the
control frame is installed in any other location, this dimension must be a minimum of 44 mm (1.7 in.).
F

(3) Minimum distance from the top of the mounting rails to the top of the enclosure.
G
(4)
(4) Minimum distance from the top of the mounting rails to the enclosure floor. If the choke is installed in another location, the
distance must be greater than 590 mm (23.2 in.)
H
