Description
2.8 Communication and system connection
3WA1 air circuit breaker
146 Equipment Manual, 02/2023, 92310000002-06
The following graphic shows the interconnection of the COM190 communications
module (module role selector switch is set "A"), a PSS COM, and an external write
protection switch.
Connections X63/X64
Connections X63 and X64 are the Switched Ethernet connections of the COM190
communications module.
If the communications module is mounted on the secondary disconnect terminal of the
circuit breaker, the space for the Ethernet connectors is restricted by the control cabinet
door.
The available space can be used optimally, e.g. by selecting suitable plugs. Examples
include:
• 90° right-angled connector, e.g. PROFINET connector 6GK1901-1BB20-2AA0
• Flat ribbon cable with short Ethernet connector
If it is not possible to use the above-mentioned Ethernet connectors and the available
space is not sufficient for observing the specified bending radius, the module must be
mounted externally on a DIN rail. You will find information on mounting the COM
modules on a DIN rail separate from the 3WA air circuit breaker in Chapter Mounting
adapter for CubicleBUS² modules (Page 384).
