Installing fieldbus adapter modules
Note: Pay attention to the free space required by the cabling or terminals coming to the
option modules.
1. Disconnect the inverter from the supply, lock out the disconnecting device, and ensure
by measuring that there is no voltage present.
2. Switch off any potentially dangerous control voltages coming to the inverter. Ensure by
measuring that the I/O terminals of the control unit (especially the relay output
terminals) are safe.
3. Insert the module into a free option module slot on the control unit.
4. Fasten the mounting screw of the module.
5. Connect the necessary wiring to the module following the instructions given in the
documentation of the module and section Connecting the control cables on page 46.
6. Check the installation and that it is safe to reconnect power.
7. Configure the module. Refer to the instructions given in the documentation of the
module as well as the appropriate firmware manual.
