Description
Minimum distance (in / cm)
I
If a front door exists, this is the distance between the back surface of the door and
the front surface of the vertical NEMA rail. Space is required to provide clearing for
bezel airflow.
2.5 / 6.4
J
Space required for enclosures, rails, and cable management arms.
37 / 94
K
Distance between the rack wall and the NEMA rail spacing. This space must be
large enough for the PDU to fit.
PowerMax 2000 inward-facing PDU requirements
If using an inward-facing PDU within a third-party rack, refer to the diagram below to ensure that the minimum width (F) and depth (A) of
the rack and PDU combination are sufficient for the array. Inward-facing PDUs may encroach into the service area and make serviceability
more difficult than rear-facing PDUs.

Description
Minimum distance (in / cm)
A
Minimum depth of the rack. Total value of
B+J+G+K+L
in the diagram.
B
Distance between front surface of the rack post and the NEMA rail.
C
Distance between the NEMA rails.
24 / 61
D
Distance between the rear NEMA rails to the exterior, rear surface of the rack.
17 / 43.2
E
NEMA rail spacing.
19 / 48.3
F
Minimum width of the rack. Total value of
E+H+H+M
in the diagram.
Because the AC cable bend radius (M) includes a portion of the equipment
enclosure area, only half the distance of (M) on each side of the rack is required to
determine the minimum width of the rack. The equation can be thought of as E+H
+H+½M+½M.
