avoid an accidental start of the equipment while it is
connected to operation voltage.
INFORMATION
ABB personnel must obey the instructions in
ABB CISE 15.4.
2.1 Connection
1. To install the Softstarter
see chapter 4 Installation.
INFORMATION
You can connect PSTX Softstarters In Line
1
and
Inside Delta

, see Figure 2.1.
2. Connect the main circuit: terminals 1L1 - 3L2 -
5L3 to the line side
1
, and terminals 2T1 - 4T2
- 6T3 to the motor side
2
, see Figure 2.2.. Use
wire connection for PSTX30...105, see Figure 2.2
and terminal connection for PSTX142...570, see
Figure 2.3.
3. Connect the line side to terminals 1L1, 3L2, 5L3.
see
1
and Figure 2.2. Connect the motor to
terminals 2T1, 4T2, 6T3 on the motor side, see
2
Figure 2.2 and Figure 2.3.
