INTRODUCTION
2.1 - ABOUT THIS MANUAL
This Manual describes how to install, start-up, operate and
identify the problems of the SSW-04 Soft-Starters series.
Should you require any training or further info, please contact
WEG.
This Manual is divided into 9 Chapters, providing information
to the user on how to receive, install, start-up and operate
the SSW-04:
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.
This Manual provides information for the correct use of the
SSW-04. The SSW-04 is very flexible and allows for the
operation in many different modes as described in this manual.
2.2 VERSION OF
SOFTWARE
As the SSW-04 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-04 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-04, 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-04 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-04 series is a totally microprocessor controlled SoftStarter 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 16 to 85A, 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 45A are with natural cooling and isolated
heatsink (thyristor-thyristor modules). The models from 60A
and 85A have forced cooling and isolated heatsink (ThyristorThyristor Modules).
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-04) has 2 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 switched 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.

The cross sections indicated in Table 3.1 are orientative values
only. For correct cables dimensioning consider the installation
condition and the maximum allowable voltage drop.
The recommended fuse connected at the input side must be
a ultra rapid type (UR) with I2t smaller than 75% of the value
indicated in Table 3.1 (I2t of the SCR).
When a short circuit occurs the ultra rapid fuse protects the
SCR.
Normal fuses can also be used, in that case the installation is
protected against short circuit, but the SCR isn't protected.

INSTALLATION
When installing the signal and control wiring, please note
the following:
Cable cross-section: 0.5...1.5mm2;
Relays, contactors, solenoid valves or breaking coils
installed near to Soft-Starters can generate interferences in
the control circuit. To eliminate this , you must install
RC supressors connected in parallel with the coils of these
devices, when fed by alternate current and free wheel
diodes when fed by direct current.
When an extern HMI is used, the connection cable to the
Soft-Starter should be passed through the slot at the bottom
of the Soft-Starter. This cable must be laid separate from the
other cables existing in the installation, maintaining a
distance of 100mm (3.94in) each other.
3.2.4 - FAN
CONNECTIONS
Max. recommended torque in the terminals X2 and X1:
Maximum 0.4 Nm or 3.5lb.in.
The control wiring (X2:1...5) must be laid separate from
the power wiring.
The fan connections must be done through X1:1 and X1:2
connector according to the voltage defined by the SoftStarter code:
Ex.: SSW-04. 60/220-440/
Electronic / fan voltage:
1 = 110Vac

Note: It's necessary to use normal fuses or breaker to protect
the installation. Ultra-Rapid fuses are not necessary for
the SSW-04 operation, but they are recommended for
SCR protection.
The transformer "T" is optional and must be utilized
when the line voltage is different than the electronics
and fan voltage.
The isolation contactor "K1" is optional, and is not
necessary for the SSW-04 operation. However due to
protection and safety reasons it's recommended. In case
