3.1.4 - Connections<br />
Within the Motor<br />
Delta Connection<br />
When connection is made within the motor connect as delta<br />
connection, follows :<br />
NOTE!<br />
1)The connection cables of the Soft-Starter to the line supply,<br />
or the line supply isolation contactor must be able to carry<br />
the motor rated current, and the motor connection cables to<br />
the Soft-Starter, and/or the bypass contactor must be able to<br />
carry 58% of the motor rated current.<br />
2) Due to the high currents and cable cross sections, it is also<br />
suggested to use copper bus bar for this type of connection.<br />
3)When 2 poles motors are in full voltage it is necessary a<br />
minimum of 25% of load applied to its axle. When this condition<br />
can not be taken, a bypass contactor is necessary.<br />
NOTE!<br />
SSW-03 Plus is supplied with an extension bus bar to enable the<br />
connection of more cables to the SSW-03 Plus input bus bar.<br />
Do not use this extension bus bar when SSW-03 Plus connection<br />
to line supply is made by means of bus bar.<br />
The drawing below is orientative. Depending on the Soft-Starter<br />
type, the extension bus bar may have one, two or three holes.<br />
