Configuration

Mounting
Attach the busbar from below to the rear terminals L1, L2 and L3 of the 3RM1 motor starter.
The outgoing feeders to the motors thus remain accessible.
Figure 4-1
Hazardous Voltage.
Can Cause Death, Serious Injury, or Property Damage.
If free and uncovered terminal lugs are touched when the load voltage is switched on,
death or serious injury can result.
For this reason, always cover the free terminal lugs (= free slots that are unassigned for
thermal reasons, for example) with a cover cap. The cover caps are available as
accessories.
Energy is supplied via the infeed terminal 3RM1920-1AA. This means you can connect
conductors with a cross-section of 1.5 mm² to 4 mm².
