Installation Guidelines
Possible Configurations on Mounting Rack ER 701-3
Use expansion mounting rack ER 701-3 to install expansion unit EU 3. EU 3 is suitable for con-
nection to a centrally configured or remote CC 2/CC 3 central controller. ER 701-3 has slots for a
power supply module (PS), digital and analog input or output modules, communications
processors and intelligent input/output modules (interrupt-triggering modules can only be used
via an IM 307/317), one central controller interface module, and one IM 306 expansion unit
interface module. The IM 306 lets you connect up to three EU 1 expansion units to one EU 3
expansion unit.
Use the IM 310, IM 311, IM 314 and 318 central controller interface modules to connect the EU 3
to the S5-135U, S5-150U and S5-155U programmable controllers.
