 SEM3™ Metered Bus Plug for SENTRON Busway Systems

9.0 Additions to the Network

If additional plugs are required after an initial installation, 
one of two procedures should be followed.

If there is inadequate controller metering capacity, such that 
the new meters cannot be connected to an existing installed 
controller bus plug, a new controller bus plug must be 
installed. This plug will NOT be "daisy chained" to any 
neighbors, and addressing the rack is not required (default 
setting 

0

). CAT6 cable must be run from the 

PC

 port to the 

selected data aggregator. See Section 6.3 for CAT6 wiring 
instructions. Refer to Section 7.0 for commissioning an 
additional controller. 

If the existing installation allows for any meters in an 
additional plug to be uniquely addressed, then a controller 
plug is not required. Simply install the additional plug per 
Section 6.0. The rotary switch must be set so as to uniquely 
address the meters in the new bus plug, see Section 7.3 to 
address the meter rack appropriately. "Daisy chain" the 
isolated communication cable to the neighboring plug per 
Section 6.3. The meters will be visible via the controller they 
are connected to. 

If a SCADA system is integrated with the SEM3™ network, 
additional steps may be required to integrate any system 
modifications or new metering points. See Section 10.0.
