Warning!
Before connecting the PSE18...PSE170 to operational voltage(Ue) for
the fi rst time, the supply voltage(Us) must be connected and turned
on to ensure the bypass relay is switched to open position. This is
necessary to avoid unintentional starting of the equipment during the
connection.
1. Be aware of the ambient temperature. Derating is required above 40 °C
(104 °F). See chapter 3.6.
2. Mount the softstarter according to Chapter 4 Mounting.

Warning!
Hazardous voltage. Will cause death or serious injury. Turn off and
lock out all power supplying this device before starting work on this
equipment.
3. Connect the terminals 1 L1, 3 L2 and 5 L3 to the operational voltage on the
power supply line side.
4. Connect the terminals 2T1, 4T2 and 6T3 to the motor.
Warning!
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 such capacitors are to be used, they should be connected on the line side of the
softstarter.

The earthing is not a protective earth, it is a functional earth. The earthing
cable should be as short as possible. Maximum length 0.5 m. The earthing
cable should be connected to the mounting plate, which should also be
earthed.
7. Connect the start, stop and other control circuits including the analog out to
the terminals, 8, 9, 10, 11, 12, 13 if needed. This section is using an internal
24 V DC. Do not feed with any external voltage.

8. Connect terminals 3, 4, 5, 6 and 7 when using the signal output relays. These
are potential free contacts for maximum 250 V AC, 1,5 A AC-15. Make sure
you are using the same voltage level within this terminal section.

D
When the rated current of the motor is
reached, press the Select key again to save.
If needed, continue to set other parameters
according to the application following the
same procedure.
Press the Exit key to return to the top level.
Warning!
The same external voltage (maximum 24 V DC or maximum 250 V
AC) must be connected to the output relay terminals 3, 4, 5, 6 and 7.
Failure to observe the above may damage the softstarter and the warranty may no longer be valid.
9. Switch ON the control supply voltage Us, terminals 1 and 2.
10. Continue to confi gure parameter Ie as described in fi gure 2.3. Complete
information about confi guration is available in Chapter 6 Human-Machine
Interface (HMI) and Chapter 7 Functions and confi guration.
11. Switch ON the operational voltage Ue. The green “Ready” LED will turn solid.
12. Give start command to the softstarter.
Warning!
Depending on the two phase control, a connected motor terminal
always carries live hazardous voltage. Do not touch terminals when
voltage is applied. Output terminals will have live voltage even when
the device is OFF. This can cause death or serious injury.

Figure 3.1: Integrated By-pass. Controlled
phases 1 and 3 (L1 and L3).
3.1 Overview
The PSE Softstarter is a microprocessor-based softstarter designed with the latest
technology for soft starting and soft stopping of three-phase squirrel cage motors.
The softstarter has several advanced features as standard.
• Integrated by-pass in phases L1 and L3, see fi gure 3.1.
• Thyristors are used on phases L1 and L3 for controlling the motor voltage.
1SFC132253F0001
• Select between voltage ramp or torque control during start and stop.
• Motor protection, as well as underload and locked rotor protection.
The keypad on the front is designed to be as user-friendly as possible, with a clear
display showing icons.
The PSE Softstarter can be controlled in two ways:
• Hardwire inputs control
• Fieldbus communication interface
Only one type of control method can be enabled simultaneously. Default selection
is hardwire inputs control.
The integrated fans for cooling are operated only during ramping ( start/stop) and
when the temperature of the heat sink is high. The temperature is monitored by a
thermistor mounted on the heat sink.
Phase L2 is directly connected to the motor, see fi gure 3.1.
Figure 3.2: Torque control is offered as standard
with the PSE softstarter.
Check that you have the correct product in regards to operational voltage, control
supply voltage and rated motor data. See chapter 3.3 Type designation.
The PSE18...PSE370 Softstarters operates over wide voltage ranges.
• Rated operational voltage 208 - 600 V AC
• Rated control supply voltage 100 - 250 V AC
Warning!
The product should only be used within the specifi ed ratings.
Be aware of the ambient temperature and altitude above sea level. Derating
is required above 40 °C (104 °F) and above 1000 m (3281 ft).

4.2.2 Requirements
See Chapter 3 Description for environmental requirements.
The PSE Softstarters exist in three different physical sizes which are designed to
be mounted with M6 (1/4 in.) bolts as well as bolts of equivalent dimension and
strength. Measures and drilling plans will be found in chapters 3.7.6 Dimensions
and 3.7.7 Drilling plan.
4.2.3 Minimum enclosure size
In applications where the softstarter is installed in an enclosure, the following
minimum enclosure sizes are recommended. Dimensions according to the sketch
in fi gure 4.3.
