The design of the EUs is comparable to that of the CC: they comprise
a compact housing with a type-dependent number of slots for modules
and, according to the type of EU, a cable duct, an integral power
supply unit or fan subassembly.
The mounting dimensions of the EU 183U, EU 184U and EU 185U
are the same as those of the 135U/155U CC (see Figures 4-2 and 4-4).
The EU 187U has neither power supply unit nor cable duct. Its overall
height and depth are therefore different from those mounting
dimensions of the other EUs.
