Capacitors for power factor compensation are not allowed between the
softstarter and the motor, since this can cause current peaks which can
damage the thyristors in the softstarter. If you use such capacitors, they
must be connected on the line side of the softstarter.
3. Connect control supply voltage to terminals 1 and 2.
4. Connect terminal 22 to the functional earth.
The earthing is not a protective earth, it is a functional earth.
The earthing cable must be as short as possible. Maximum length 0.5
m. The earthing cable must be connected to the mounting plate, which
must also be earthed.
Look at the diagram and connect the start/stop circuits: terminal 13,
5.
14, 18, 19 and 20/21, with the internal 24V DC terminal. When using
internal 24 V DC (terminals 20 or 21), the terminals 18 and 19 should
be connected to each other.
Terminal 15, 16 and 17 are programmable inputs for purposes such as
reset, slow speed forward, slow speed reverse, stand still brake etc.
For usage of external supply see 1SFC132081M0201 - Softstarters
Type PSTX30...PSTX1250, Installation and Commissioning Manual
available on: https://solutions.abb/softstarters
Use 24V DC only when you connect terminal 13, 14, 15, 16 and 17.
Other voltages can cause damage to the softstarter and the warranty
will no longer be valid.
6. Connect terminals 4, 5, 6, 7, 8, 9, 10, 11 and 12 to use the signal
output relays. These are potential free contacts for maximum 250 V
AC, 1.5 A AC-15 and 30 V DC, 5 A DC-12.
7. Check that the operational voltage and control supply voltage
correspond to the softstarter ratings.
8. Switch ON the control supply voltage, terminals 1 and 2.
9. Configure applicable parameters given in chapter 6,
Softstarter settings.
