1.1 Purpose of this manual
This is a manual for simplified installation, set-up and
operation of a PSTX softstarter with a waste water
pump. If the instructions in this manual are followed, the
PSTX softstarter will have the most important features
activated and controlled by hard wire. If any further
functionality or information is requested or if the PSTX
softstarter is not controlling a waste water pump, please
see 1SFC132081M0201 - Softstarters Type PSTX30...
PSTX370, Installation and Commissioning Manual,
available on http://new.abb.com/low-voltage/products/
softstarters. This manual will show how to activate:
• Soft start and stop of pump for normal operation.
• Electronic
overload protection, for detection of pump clogging.
• Current under load protection, for detection of dry
pump based on current.
• Power factor under load protection, for detection of
dry pump based on power.
• Pump cleaning with full voltage forward and fast jog
reverse.
• All inputs and outputs that are needed to get an easy
control of the PSTX softstarter using push buttons or
a PLC with hard wire.

3 Connection
This chapter describes the electrical connections as well
as connections for communication devices that can be
connected to the softstarter.
WARNING
Mounting and electrical connections of the
softstarter shall be made in accordance with
local laws and regulations and be performed by
authorized personnel.
CAUTION
Hazardous voltage. Can cause death or serious
injury. Turn off and lock out all power supplying
this device before any work on the softstarter.
WARNING!
Apply the control supply voltage to make sure
that the bypass relays are in open position before
you connect the softstarters PSTX30...PSTX170
to operational voltage for the rst time. If not, the
equipment can start accidentally. This is necessary to
avoid unintentional starting of the equipment during
the connection.
INFORMATION
ABB personell have to obey the instructions in
ABB CISE 15.4.
WARNING
Capacitors for power factor compensation
are not allowed in 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.
For more information, please see 1SFC132081M0201
- Softstarters Type PSTX30...PSTX370, Installation and
Commissioning Manual.
3.1 Main circuit
INFORMATION
The voltage dips may not be more than 5%
between softstarter and motor. The cable lenght
does not matter.
Softstarters PSTX30...PSTX370 can be connected both
In Line, see 1Figure 1,
and Inside Delta, see 2Figure 1.
Use wire connection for PSTX30...PSTX105 see Figure 2
and terminal connection for PSTX142...PSTX170
see Figure 3.
• Connect the line side to terminals 1L1, 3L2, 5L3, see
1in Figure 2 and 3.
• Connect the motor to terminals 2T1, 4T2, 6T3 on the
motor side, see 2in Figure 2 and 3.
The terminal marking is printed on the front of the
softstarter. For tightening torques and cable thickness,

3.2 Control supply and control circuit
Wires in industrial control applications are divided into
three groups: main power supply, control supply and
control circuit.
Main power supply (1L1, 3L2, 5L3, 2T1, 4T2, 6T3)
Control supply voltage (terminals1and2)
Control circuit (terminals 13 - 21).
3.2.1 Control supply voltage -
terminals1and2
Connect neutral and phase to terminal 1 and 2.
See Figure 4.
INFORMATION
Only use 100-250 V, 50 / 60 Hz supply voltage.

3.2.2 Functional earth - terminal 22
Softstarters type PSTX85...PSTX370 should be earthed
using the terminal 22 as shown in Figure 5 (one
connection is sufficient). Connect the cable to an earthing
point close to the softstarter. The cable should be as
short as possible. A suitable earthing point is next to the
softstarter on the mounting plate, which should also be
earthed.
INFORMATION
This is not a protective earth, it is a function
earth. The earthing cable should be as short as
possible. Maximum length 0.5m.
INFORMATION
Do not use functional earth in IT-networks,
commonly found in for instance marine
applications.
