3.2.4.3 Control Fuse
The fuse rated current should preferably be equal to or higher than
the motor starting current in order to prevent cyclic overloads and
the tripping of the fuse in the prohibited area of the Time x Current
curve.
The proper sizing of the fuse should take into account: the local
standards for electrical installations, the starting cycle, number
of starts per hour, starting current and starting time, ambient
temperature and altitude.

The Soft-Starter SSW-07 is developed to be used in industrial
systems (Class A) according to Standard EN60947-4-2.
It’s necessary to have a distance of 0.25 m (10 in) between the
Soft- Starter SSW-07 control cables and motor cables.
Example: PLC wiring, temperature controllers, thermocouple cables, etc.
Grounding of the Motor frame
Always ground the motor frame. The Soft-Starter SSW-07 output

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 dierence 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

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.
