Motor Connection

ASTAT XL soft starters can be connected to the motor in-line or inside delta (also called three-wire and
six-wire connection). When connecting in inside delta, enter the motor full load current (FLC) for
parameter 1A. The ASTAT XL will automatically detect whether the motor is connected in-line or inside
delta and will calculate the correct inside delta current level.
6.1.1 Testing the Installation
The ASTAT XL can be connected to a small motor for testing. During this test, the soft starter's control
input and relay output protection settings can be tested. This test mode is not suitable for testing soft
starting or soft stopping performance.
The FLC of the test motor must be at least 2% of the soft starter's minimum FLC (see Minimum and
Maximum Current Settings on page 11).
NOTE
When testing the soft starter with a small motor, set parameter 1A Motor Full Load Current to
the minimum allowable value.
Models which are internally bypassed do not require an external bypass contactor.
