ATTENTION!
Please check which type of connection is used to connect the SSW-03 Plus to the motor: standard connection or SSW-03 Plus is connected within the motor Delta connection.
Standard connection with three cables: the line current of the Soft-Starter is equal to the motor current.
SSW-03 Plus is connected within the motor Delta con­nection with six leads: the line current of the Soft-Starter
is approximately 58% of the motor current.
ATTENTION!
To connect the SSW-03 Plus within the Motor Delta connec­tion, the motor must permit the Delta connection in the de­sired voltage.

INTRODUCTION
2.1 - ABOUT THIS MANUAL
This Manual describes how to install, start-up, operate and identify the problems of the SSW-03 Plus Soft-Starters series.
Should you require any training or further info, please contact WEG.
This Manual is divided into 10 Chapters, providing information to the user on how to receive, install, start-up and operate the SSW-03 Plus:
Chapter 1- Safety Notices; Chapter 2 - Introduction; Chapter 3 - Installation; Chapter 4 - Power-up / Commissioning; Chapter 5 - Use of the HMI; Chapter 6 - Detailed Parameter Description; Chapter 7 - Maintenance; Chapter 8 - Technical Characteristics; Chapter 9 - Appendix; Chapter 10- Optional Devices.
This Manual provides information for the correct use of the SSW-03 Plus. The SSW-03 Plus is very flexible and allows for the operation in many different modes as described in this manual.
As the SSW-03 Plus can be applied in several ways, it is impossible to describe here all of the application possibilities. WEG does not accept any responsibility when the SSW-03 Plus is not used according to this Manual.
No part of this Manual may be reproduced in any form, without the written permission of WEG.
It is important to note the Software Version installed in the Version SSW-03 Plus, since it defines the functions and the programming parameters of the Soft-Starter. This Manual refers to the Software version indicated on the inside cover. For example, the Version 1.XX applies to versions
1.00 to 1.99, where “X” is a variable that will change due to minor software revisions. The operation of the SSW-03 Plus with these software revisions are still covered by this version of the Manual.
The Software Version can be read in the Parameter P71.

2.4 - ABOUT THE SSW-03 PLUS
The SSW-03 Plus series is a totally microprocessor controlled Soft-Starter series which controls the starting current of three­phase induction motors. In this way mechanical inmpacts on the load and current peaks on the supply network are prevented.
2.4.1 - Introduction
This series includes models from 120 to 1400A, being supplied from 220V, 230V, 240V, 380V, 400V, 415V, 440V, 460V, 480V, 525V or 575V. (The available types are listed in Section 8).
The models up to 205A are fitted with forced cooling and isolated heatsink (thyristor-thyristor modules). The models from 255A up to 1400A have forced cooling and energized heatsink. (Disc thyristors).
The electronic control circuit uses a 16 bit microprocessor with high performance, allowing settings and displaying by means of the interface (keypad + display) of all needed parameters.
Depending on the power, this series (SSW-03 Plus) has 8 different construction forms, as shown in Figure 2.1.

INTRODUCTION
2.4.2 - Simplified Block Diagram of the SSW-03 Plus
In the power stage, the line voltage is controlled by means of 6 SCR’s that allow the variation of the conduction angle of the voltage supplied to the motor.
For the internal supply of the electronics, a linear source is used with several voltages, fed independently of the power supply.
The control board contains the circuits responsible for the control, monitoring and protection of the power components. This board also contains the control and signalling circuit to be used by the user according to its application as a relay output.
All parameters or controls for the operation of the Soft-Starter can be displayed or changed through the HMI.

GROUNDING CONNECTIONS
ATTENTION!
The connection of the motor to the Soft-Starter must be realized carefully. Follow strictly the connection diagrams according to the winding types shown in figure 3.5 and item 6.4.1.
If reversal of motor direction of rotation is required, change the Soft-Starter connection to the line supply. Ensure that power is switched OFF while connections are changed.
Do not start motor with wrong P28 content:
OFF = standard connection ON = within the motor delta connection
DANGER!
AC input disconnect: provide an AC input disconnecting switch to switch OFF input power to the Soft-Starter. This device shall disconnect the Soft-Starter from the AC input supply when required (e.g. during maintenance services).
DANGER!
The AC input disconnect cannot be used as an emergency stop device.
DANGER!
Be sure that the AC input power is disconnected before making any terminal connection.
DANGER!
The information below will be a guide to achieve a proper installation. Follow also all applicable local standards for electrical installations.
ATTENTION!
Provide at least 10 in (0.25m) spacing between low voltage wiring and the Soft-Starter. , line or load reactors, AC input power, and AC motor cables.
ATTENTION!
Control of overvoltage in the line that supply the Soft-Starter must be made using protective of surge with voltage of 550Vac (for models 220 - 440Vac) and 680Vac (for models 460 - 575Vac) connection phase to phase, and absortion energy capacity of 80 joules.

The line voltage must be compatible with the rated voltage
of the Soft-Starter.
For installation use the cable cross sections and the fuses recommended in Table 3.1, 3.2, 3.3, 3.4. Maximum torque as indicated in table 3.5.
Power factor correction capacitors must never be installed
on the Soft-Starter output.
The Soft-Starters must be grounded. For this purpose use a cable with a cross section as indicated in Tables 3.2, 3.3, 3.4. Connect it to a specific grounding bar or to the general grounding point (resistance 10 ohms). Do not share the grounding wiring with other equipment which operate at high currents (for instance, high voltage motors, welding machines, etc.). If several Soft-Starters are used together, see Figure 3.6.

Soft-Starter
Grounding bar Internal to the panel
The Soft-Starter is fitted with electronic protection against motor overloads. This protection must be set according to the specific motor. When several motors are connected to the same Soft-Starter, use individual overload relays for each motor.
If a isolating switch or a contactor is inserted in the motor supply, do not operate them with running motor or when the Soft-Starter is enabled.
