The installation of the bottom plate is easier while the back panel is outside the enclosure. The
curved leading edge of the bottom duct adapter is to the front of the frequency converter and
down.
Before installing the back panel with the fre-
quency converter in the Rittal TS8 enclosure
remove and discard the rearmost 5 screws
(see illustration below) located on the top cov-
er of the frequency converter. The holes will
be used to fasten the top ductwork with longer
screws provided with the kit.
Install the back panel in the enclosure, see il-
lustration below. Use Rittal PS4593.000 brack-
ets (minimum one per side at the middle of
the frequency converter) with appropriate
support strip for additional support of the back
panel. For the D4 and E2 frame use two sup-
ports per side. If additional components are
mounted on the same back panel, consult Rit-
tal manual for additional support require-
ments.
