The 3RW44 soft starter automatically detects how it is connected, meaning that the
connection type does not have to be explicitly set on the device. The detected connection
type can be read on the starter in the "Status display/Type of connection" menu item. In this
case, the display reads "Inside-delta circuit". If the circuitry is faulty or the motor is not
connected, the display shows "Unknown".
NOTICE
The rated motor current given on the nameplate must always be set in the quick start menu
or in the motor adjustment menu item. This setting is independent of the soft starter's type
of connection.
Value to be set in the above example for a line voltage of 400 V, e.g. 40.5 A.
NOTICE
The DC braking and combined braking device functions are no longer available for inside-
delta circuits.
To ensure proper functioning of the soft starter, the electrical connection of the main
voltage (line and motor side) must be made according to the given circuit examples (see
chapter Connection examples for main and control circuits (Page 216)).
