Installation Guidelines S5-115F Manual
Possible configurations on mountning rack ER 701-3
The modules on an ER 701-3 mounting rack form an EU 3. The EU 3 is suitable for
• Connection to a central controller (CC) in centralized configurations
or
• Connection to a distributed EU 2 or EU 3 in centralized configurations
or
• Connection to a CC, EU 1 or EU 2 in distributed configurations.
Note
You must always use an EU 3 if you want to operate several safety-related 463 AI
modules or CP 523 communications processors in one expansion unit.
When the AE 463 is used in a central configurated ER 701-3 with IM 306 please notice:
• the 705 connecting cable must not longer than 0.5 m
• it is not allowed to use the AE 463 in the third expansion unit (EU)
The ER 701-3 has slots for a power supply module, digital and analog input or output modules, the
CP 523 as well as the IM 306 and IM 314 EU interface modules.
1 Only required in the case of distributed configurations
2 Except the 6ES5 434-7LA12 interrupt input module
3 Also for the 6ES5 463-4UA11 safety-related AI module
4 Only in the case of distributed configurations
