Terminal box<br />
<strong>Lenze</strong>'s <strong>three</strong>-<strong>phase</strong> <strong>AC</strong> motor features a larger terminal<br />
box in which all connections are clearly arranged. The terminal<br />
box is located at the top of IM B3 design <strong>motors</strong>.<br />

Motor connection<br />
The <strong>three</strong>-<strong>phase</strong> <strong>AC</strong> <strong>motors</strong> are designed for operation on a<br />
constant mains and for inverter operation.<br />
For operation at 50 Hz, the <strong>motors</strong> should be operated in<br />
a Δ-connection at 230 V or in a Y-connection at 400 V.<br />
For inverter operation, the base frequency has been set<br />
at 87 Hz at a rated voltage of 400 V in a Δ-connection.<br />
For this purpose, the <strong>motors</strong> should be connected in a<br />
Δ-connection.<br />
for the brakes. The terminal box has a built-in DIN rail for<br />
up to 18 possible connections.<br />
