6.8 Front connector for the I/O modules
ET 200MP Distributed I/O System
64 System Manual, 01/2013, A5E03723484-01
The front connector is characterized by the following:
● 40 clamping points each
● Clamping technology: Screw
● If you want to supply load groups with the same potential (non-isolated), use the potential
bridges supplied for the front connector. In four locations: 9 and 29, 10 and 30, 19 and
39, 20 and 40, the terminals can be bridged by means of potential bridges. Advantage:
Reduction of the wiring effort
Note
Please note that the potential bridges may be deployed up to a maximum rated voltage of
24 V DC! The current capacity per potential bridge is 8 A maximum.
Reference
Further information on the use of the potential bridges can be found in the Product Manual
for the respective I/O module.
