NOTE!
It is very important to check if
the Soft-Starter Software is the
same as the above.
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.

ATTENTION!
To connect the SSW-03 Plus within the Motor Delta connection, the motor must permit the Delta connection in the desired voltage.
During the start of the motor the current relation of the motor
in relation of the Soft-Starter is 1.50. However in full voltage
condition (after the start timeof the motor) the current relation
is 1.73.

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.

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.

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.

When connection is made within the motor connect as delta
connection, follows :
NOTE!
1)The connection cables of the Soft-Starter to the line supply,
or the line supply isolation contactor must be able to carry
the motor rated current, and the motor connection cables to
the Soft-Starter, and/or the bypass contactor must be able to
carry 58% of the motor rated current.
2) Due to the high currents and cable cross sections, it is also
suggested to use copper bus bar for this type of connection.
3)When 2 poles motors are in full voltage it is necessary a
minimum of 25% ofload applied to its axle. When thiscondition
can not be taken, a bypass contactor is necessary.
NOTE!

INSTALLATION
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.

Do not use the neutral conductor for grounding purpose.
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.
