6.3.3 Load type
This is where you select whether the motor starter should protect a single-phase or a
three-phase load.
Note
Reversing starter
1-phase loads are not permissible on the reversing starter. 1-phase operation is also not
permissible after activation of the "EX motor" parameter in the case of fail-safe direct
motor starters.

3-phase operation
In 3-phase operation, you can operate a 3-phase asynchronous motor at the connections of
the motor starter.
To ensure motor protection, do not connect more than one motor to one motor starter.
Do not operate several single-phase motors on one motor starter in three-phase operation.
1-phase operation
In 1-phase operation, you can operate a 1-phase asynchronous motor at the connections of
the motor starter. 1-phase operation is only possible when using a direct-on-line starter. The
relevant three-pole tripping characteristics apply to single-phase operation.
Feed in the line voltage on terminals L1 and L2(N) only and connect the single-phase motor
to the terminals T1 and T2 only.
An ATEX application in 1-phase operation is not possible with the motor starter.
