3.2.4 Power Supply Connection to the Soft-Starter SSW-08
DANGER!
The AC input must be compatible with the voltage range of the Soft-Starter SSW-08.
DANGER!
Provide a power supply disconnecting switch for the Soft-Starter SSW-08. This
disconnecting switch must disconnect the AC input voltage to the Soft-Starter
SSW-08 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-08 is enabled.
ATTENTION!
Over-voltage control in the line that supplies the Soft-Starter must be made using over-
voltage protections of 680 Vac (phase to phase connection) and energy absorption
capacity of 40 joules (17 A to 200 A models) and 80 joules (255 A to 412 A models).
NOTE!
Use the wire sizes and fuses recommended in tables 3.5, 3.6 and 3.7. The connector
tightening torque is indicated in table 3.4. Use only copper wires 70 °C (158 °F).
