DANGER!
Power factor correction capacitors should never be fitted to the output
of the Soft-Starter SSW-06 (U / 2T1, V / 4T2 and W / 6T3).
ATTENTION!
For the protection based on the current reading and indication to work
correctly, in case of overload protection, the nominal current of the
motor cannot be lower than 30% of the nominal current of the SSW-06
Soft-Starter.
It is not recommended to use motors with the load working duty lower
than 50% of its nominal current.
NOTE!
Use wire sizing and fuses as recommended in table 3.6, 3.7 and 3.9.
The connector tightening torque is as indicated in table 3.5. Use 70ºC
(158ºF) copper wires only.
NOTE!
Soft-Starter SSW-06 is provided with an electronic protection against
motor overload. This protection must be set according to the specific
motor. When several motors are connected to the same Soft-Starter
SSW-06, use individual overload relays for each motor.
The SSW-06 Soft-Starter can be connected to the motor in two ways,
according to items 3.2.5.1 and 3.2.5.2.
3.2.5 Connection of the
SSW-06 Soft-Starter
to the motor
3.2.5.1 Standard Three-Wire
Connection
(P150=0=Inactive)
The standard 3 wire connection allows the SSW-06 Soft-Starter line
current to be equal to the motor current.
