7.1
Motor Connection
VersiStart i III 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 VersiStart i III will automatically detect whether
the motor is connected in-line or inside delta and will calculate the correct inside delta current level.
7.1.1
Testing the Installation
The VersiStart i III 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 (refer to Minimum and Maximum Current Settings on
page 10).
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.
