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