USER MANUAL

DANGER

CAUTION

NOTE

Before gaining access to the components inside the inverter, remove voltage from the inverter and wait at least 20 minutes. Wait for a complete discharge of the internal capacitors to avoid any electric shock hazard.

Electric shock hazard: do not connect/disconnect the signal terminals or the power terminals when the inverter is on. This also prevents the inverter from being damaged.

All the screws used to fasten removable parts (terminals cover, serial interface connector, cable plates, etc.) are black, round-head, cross-head screws.

When wiring the inverter, remove only this type of screws. If different screws or bolts are removed, the inverter warranty will be no longer valid.

1) Remove voltage from the inverter and wait at least 20 minutes.

2) The electronic components in the inverter and the communications board are sensitive to electrostatic discharge. Be careful when you reach the component parts inside the inverter and when you handle the communications board. The board should be installed in a workstation equipped with proper grounding and provided with an antistatic surface. If this is not possible, the installer must wear a ground bracelet properly connected to the PE conductor.

3) Loosen the two front screws located in the lower part of the inverter cover to remove the covering of the terminal board. In the drive control board, you can then reach the slot B, where you can install the Profibus communications board.

4) Insert the communications board in the slot B; make sure that the connector bar in the board is inserted in the front part of the slot only, and that the last 6 pins are not connected. If installation is correct, the three fastening holes will match with the housings of the fastening screws for the fixing

spacers. Tighten the board fixing screws as shown in Figure 87 and Figure 88.

5) Configure the DIP-switches and rotary-switches following the instructions given in the relevant section.

6) Connect the Fieldbus cable by inserting its connector or by connecting the wires to the terminals.

7) Close the inverter frame by reassembling the cover allowing gaining access to the inverter control terminals.
