Technical Description of the Expansion Units
The design of the EUs is comparable to that of the CC: they comprise a
compact housing with a type-dependant number of slots for modules and,
according to the type of EU, a cable duct, an integral power supply unit or
fan subassembly.
compact housing with a type-dependant 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 Figs. 4-3 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.
