CHAPTER 3 - INSTALLATION AND CONNECTION
47
DANGER!
The AC input voltage must be compatible with the Soft-Starter SSW-
06 nominal voltage.
DANGER!
Provide a power supply disconnecting switch. This disconnecting swi-
tch must disconnect the AC input voltage from the Soft-Starter SSW-
06, when ever required (for instance during maintenance services).
DANGER!
If a disconnect switch or a contactor is inserted in the motor supply
line, DO NOT operate these devices with a running motor or when the
Soft-Starter SSW-06 is enabled.
ATTENTION!
Control of overvoltage in the line that supplies the Soft-Starter must
be made using surge protection with a voltage of 680Vac (phase to
phaseconnection)andenergyabsorptioncapacityof40joules(for
modelsfrom10Ato205A)and80joules(formodelsfrom255Ato
1400A), all for 220 to 575 Vac models.
NOTE!
Use wire sizing as recommended in tables 3.6 and 3.7. The correct
tightening torque for the connector can be found in table 3.5. Use
70ºC (158ºF) copper wires only.
