When you receive the AC drive, the control unit contains the standard control interface. If you
included special options in your order, the AC drive will be as in your order. On the next
pages, you will find information on the terminals and general wiring examples.
It is possible to use the drive with an external power source with these properties: +24 VDC
±10%, minimum 1000 mA. Connect the external power source to terminal 30. This voltage is
sufficient to keep the control unit on and for you to set the parameters. The measurements
of the main circuit (for example, the DC link voltage, and the unit temperature) are not
available when the drive is not connected to mains.
The status LED of the drive shows the status of the drive. The status LED is located in the
control panel, below the keypad, and it can show 5 different statuses.
