3.1 Mounting
The EMS2 system includes two types of adapters:
•
Top-hat rail adapter EMS2-XTH
The motor starter is supplied via terminals on the adapter. The adapter is
mounted on a top-hat rail and the starter is inserted into the adapter.
•
Busbar adapter
•
Classic EMS2-XBB60
Power to the busbar adapters is supplied by a busbar which runs along
the back. It is not necessary to supply the individual starters.
In addition, EMS2-ROSF motor starters are compatible with the Motor
Starter Feeder System (MSFS).
