Configuration
The interfaces of the TM31 and TM15 Terminal Modules are
available for communication with the higher level. Additional
terminal strips can be used to connect the circuit breaker or
external protection and monitoring devices. The following tables
give an overview of the type and preassignment of the interfaces
in the standard version.
Note:
For max. conductor cross-section and further technical
data on TM31 and TM15 Terminal Modules,
