DANGER!
The AC input must be compatible with the voltage range of the
Soft-Starter SSW-07.
DANGER!
Provide a power supply disconnecting switch for the Soft-Starter
SSW-07. This disconnecting switch must disconnect the AC input
voltage to the Soft-Starter SSW-07 whenever necessary (for
example: during maintenance services).
If a disconnected switch or a contactor is inserted in the motor supply
line never operate these devices with the motor running or when
the Soft-Starter SSW-07 is enabled.
ATTENTION!
The overvoltage control in the line that feeds the soft-starter must
be done using overvoltage suppressors with a clamping voltage of
680 Vac (phase-to-phase connection) and an energy absorption
capability of 40 joules (17 A to 200 A models) and 80 joules (255 A
to 412 A models).
CHAPTER 3 - INSTALLATION AND CONNECTION
NOTE!
Use the wire sizes and fuses recommended in tables 3.5 and 3.7.
The connector tightening torque is indicated in table 3.4. Use only
copper wires 70 °C (158 °F).
3.2.4.1 Power Supply Capacity
The Soft-Starter SSW-07 is suitable to be used in a circuit capable
of supplying not more than X (according to table 3.6) symmetrical
rms amperes, Y maximum volts when protected by ultra-rapid fuses.

The SSW-07 can be installed on power supplies with a higher
fault level, if it is protected by ultra-rapid fuses with an adequate
2
interrupting current and an I
t according to item 3.2.4.2.
English
3.2.4.2 Recommended Fuses
The fuses to be used on the input must be high speed semiconductor
fuses with l2t lower or equal to 75 % of the SCR value indicated in
2
table 3.7 (A
s). The fuse rated current should preferably be equal or
greater than the motor starting current to avoid cyclic overloads and
fuse opening in the forbidden region of the Time x Current curve.
These fuses will protect the SSW-07 in case of a short-circuit.
Normal fuses can also be used, instead of the high speed, which will protect
the installation from short-circuits, but the SSW-07 will not be protected.
For the electronic supply protection of the SSW-07 must be used
fuse type D, or circuit breaker type C as specied in table 3.7.

3.3 RECOMMENDED SET-UPS
Some recommended set-ups are shown here and they can be
completely or partly used.
The main warning notes for all the recommended set-ups are
shown below and are described in the schemes by their respective
numbers.
NOTES!
The use of fuses or circuit breakers at the input circuit is
1
necessary for the entire installation protection. It is not necessary
to use ultra-fast fuses for the SSW-07 operation; however, their
use is recommended for the soft-starter complete protection.
The transformer “T1” is optional and must be used when there
2
is a difference between the line voltage and the electronic power
voltage.
In case that damage at the SSW-07 Soft-Starter power circuit
3
keeps the motor running (e.g., shorted thyristors), the motor
protection is obtained with the use of the power isolating
contactor (K1) or circuit breaker (Q1).
English
Start push-button.
4
Stop push-button.
5
Start/Stop switch. Bear in mind that when using two-wire digital
6
input command (normally open switch with retention), in case
of a power interruption, upon return of power, the motor will be
started immediately if the switch remains closed.
In case of maintenance of the Soft-Starter SSW-07 or the motor
7
it is necessary to remove the input fuses or disconnect the power
supply to ensure the complete equipment disconnection from
the power supply.
The emergency stop can be used by disconnecting the
8
electronics power supply.

Type Setting
Figure 4.1 - Control type setting
Select the type of starting control that best adapts to the application.
Voltage Ramp Starting:
This is the most commonly used method. Very easy to program
and set.
The Soft-Starter SSW-07 imposes the voltage applied to the motor.
Generally applied to loads with a lower initial torque or a square
torque.
This kind of control can be used as an initial working test.
Current Limit Starting:
The maximum current level is maintained during the start, being set
according to the application necessities.
Generally applied to loads with a higher initial torque or a constant
torque.
This kind of control is used to adapt the start to the capacity limits
of the supply network.
NOTES!
1. The Current Ramp control type, is only programmed using keypad
or serial communication. See the Programming Manual for more
details.
2. To program the control type in Pump control, see the Programming
