5.2.3 Connection of the operational power circuit

The softstarter is recommended to be connected with a line contactor as de-
scribed in figure 5.1. Additional circuit diagrams will be found in Chapter 11 Wiring
diagrams.
Softstarters PSE18...PSE105 are provided with built-in cable clamps. The cables
must be stripped before connection, and the length of the exposed wire should
be 20 mm or 0.8 in. Connect according to figures 5.3 and 5.5.
For Softstarters PSE142...PSE370 the cables must have lugs and be connected
to the terminal bars, according to figure 5.4 and 5.5.
Connect the line side to terminals 1L1, 3L2, 5L3.
Connect the motor to terminals 2T1, 4T2, 6T3.
The terminals marking are printed on the front of the softstarter.

Warning!
Capacitors for power factor compensation are not allowed between the
softstarter and the motor, since this can cause current peaks which can
burn the thyristors in the softstarter. If such capacitors are to be used, they
should be connected on the line side of the softstarter.
