Installation Guidelines
Connection with IM 304/IM 314 Interface Modules
Plug the IM 304 interface module into a CR 700-2/-3-0LB central rack to connect as many as four
EUs per interface to the CC. Plug an IM 314 into each ER 701-2 or ER 701-3 expansion rack. Connect
the interface modules with the 6ES5 721-.... connecting cable as shown in Figure 3-20.
Connections with the IM 304/IM 314 interface modules have the following special features:
•
Using the IM 304/IM 314 symmetrical interface modules, you can connect EUs on ER 701-2 or
ER 701-3 expansion racks with full address bus to CCs of the S5-115U, S5-135U, S5-150U, and
S5-150S and S5-155U systems.
•
Connection to EU 183, EU 185 and EU 186 is possible.
•
You can use the extended address set for the programmable controllers mentioned above
(see the IM 304/IM 314 manual).
•
Always insert a 6ES5 760-1AA11 termination connector in the receptacle for the lower front
connector (X4) on the last IM 314.
•
The potential difference between CC and EU must not exceed 7 V. An equipotential bonding
conductor should therefore be provided!
