• Active device via power cable (patch) on power strip

• Power strip via supply line (or power cable (patch)) on UPS

Requirement:

• Power strip with internal port interconnection (port matrix). The output ports must be connected to the feed line. Power strip type: PDU

• Active device via power cable (patch) on power strip

• Power strip via lead on fuse element

• Fuse element via supply line to UPS

Requirement:

• Power strip with internal port interconnection (port matrix). The output ports must be connected to the feed line. Power strip type: PDU

• Security element with internal port interconnection (port matrix). Input connector to output connector. Type: PDU

Remarks:

PDUs such as power strips, socket strips, etc. can have an internal connection of the output to the input ports. This means that the cabling route to the UPS is continued through the PDU. Modular power strips are currently excluded from this, as output and input ports are not on the same device.

The respective phase can be mapped, for example, using tags on the fuse element or the supply port.

Further cabling (sockets, etc.) is only possible as a chain (i.e. a cable from device to device).
