Risk of injury from automatic restart
When you mount the the 3DI/LC module, the motor starter can switch on autonomously if
an ON command (DI1 to DI3) is active. This can result in property damage or serious injury
caused by connected devices that are automatically started up.
Revoke the ON commands at DI1 to DI3 before mounting the 3DI/LC module.
Proceed as follows to mount a 3DI/LC module onto a motor starter:
1. Wire the 3DI/LC module according to the connection diagram.
Note
Connecting the 3DI/LC module
You will find out how to connect the 3DI/LC module in chapter "Connecting the 3DI/LC
module for the motor starter (Page 97)".
2. Slide the 3DI/LC module into the motor starter until the 3DI/LC module engages.
