DETAILED PARAMETER DESCRIPTION
Within the motor delta connection with motor double delta
serial connected.
Within the motor delta connection with motor double delta
parallel connected.
ATTENTION!
To perform the connection within the motor delta connection,
your motor must have the correct delta connection voltage.
NOTE!
1)When the connection within the motor delta connection is
used, as shown in Item 9.9, 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 con-
tactor 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 to
connect the Soft-Starter to the line supply.
3) For 2 pole motors must have a minimum 25% load applied
to the axle when in full voltage. A ByPass contactor is neces-
sary when that condition are not possible.
