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 con-
nection 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 connec-
tion, the motor must permit the Delta connection in the de-
sired voltage.

2INTRODUCTION
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 three-
phase 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.

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.

Max. Cont.: It's the maximum current that the Soft-Starter can
have in continuous duty. For this current the Soft-Starter can
only have 1 start per hour.
The SSW-03 Plus is supplied in cardboard boxes up to 205A,
current sizes from 255 to 1400A are supplied in wood crates.
The outside of the packing container has a nameplate that is
the identical to that on the SSW-03 Plus. Please check if the
SSW-03 Plus is the one you ordered.
Open the box, remove the foam and then remove the SSW-03
Plus.
For sizes above 255 A, open the wooden crate on the floor,
remove the fastening bolts on the base and remove the SSW-
03 Plus with the aid of a hoist.
Check if:
SSW-03 Plus nameplate data matches the purchase order;
The equipment has not been damaged during transport.
If any problem is detected, contact the carrier immediately.
If the SSW-03 Plus is not to be installed immediately, store it
in a clean and dry room (Storage temperatures between -
25°C and 60°C). Cover it to prevent dust, dirt or other
contamination.
