2.2.1 Layout and Fastening of the NCU/ NX Modules
Fastening of the NCU 7x0/ NX Modules
For the fastening of the NCU / NX modules, a differentiation is made between fastening
using direct installation, using fastening clip or using spacers.
The fastening of the NX component to the NCU differs depending on whether an NCU 710 or
an NCU 720/730 is used (cooling fins on the rear side of the NCU 720/730).
