AFE in IP21 Rittal Enclosure—Installation/Wiring Chapter 2
Routing the AC Input, Ground (PE), and DC Bus Output Wiring for AFE
in IP21 Rittal Enclosure
Frame 10
The AC input and ground (PE) wiring for the IP21 Rittal enclosure can be
routed through either the bottom of the enclosure, or through the bottom right
side of the enclosure (see shaded area in figure below).
The DC bus output wiring for the IP21 Rittal enclosure must be routed through
the top right side of the enclosure (see shaded area in figure below).

Frame 13
The AC input, ground (PE), and DC bus output are located in the right-most
bay (see front view of
Figure 31 ). The AC input, ground, and DC bus output
wiring can be routed through the top, bottom, or right side of the right-most bay.
ATTENTION: To minimize disruption of air flow through the enclosure and
avoid overheating within the AFE enclosure, remove only the minimum area
needed to route the power cables. In addition, remove only the minimum area
from the enclosure within the shaded areas shown in
Figure 32 for routing the
AC input, ground (PE), and DC bus output wiring. Removing sections for
routing in other areas disrupts the air flow throughout the enclosure, causing
overheating.
