Preface
Thank you for choosing INVT EC-TX803 PROFIBUS-DP communication expansion modules. EC-TX803 is a PROFIBUS-DP fieldbus communication module that needs to be used with the GD880 series VFD control box. The expansion module communicates with the bus master through PROFIBUS-DP communication protocol. This manual describes the product overview, installation, wiring, and commissioning instructions. Before installing the VFD, read through this manual carefully to ensure the proper installation and running with the excellent performance and powerful functions into full play. Product features: Communication rate: 9.6kbit/s12Mbit/s A maximum of 31 nodes can be connected when no repeater is used. If repeaters are
used, a maximum of 127 nodes (including the repeaters and master nodes) can be connected. Complies with the fieldbus standard EN50170

2 Installation and wiring
2.1 Installation precautions
Make sure the device have been powered off before installation.
Note
There are 3 expansion module interfaces on the control box (expansion slot 1, expansion slot 2, expansion slot 3). You can use any of these slots according to the actual wiring.
It is recommended to install the PROFIBUS-DP expansion module at expansion slot 3.
Required tools: Phillips screwdriver PH1, straight screwdriver SL3

2.3 Installation instructions
It is recommended to install the PROFIBUS-DP expansion module at expansion slot 3 of the control box. The following is an example of the installation at slot 3. Step 1 Place the expansion module in the corresponding position of the control box expansion slot 3, align it with the slot, and then buckle it together. Step 2 Align the expansion module positioning hole with the positioning stud. Step 3 Fix with a M3 screw. The installation is complete.

Note: The expansion module and control box are electrically connected through slots. Please
install them in place. To ensure the reliable operation of the expansion module and meet EMC requirements,
please tighten the screws according to the recommended torque for reliable grounding.
2.4 Disassembly instructions
You can disassembly the module by reversing the order of steps described in section 2.3 Installation instructions.
Step 1 Disconnect all power supplies and disassemble all cables connected to the expansion module.
Step 2 Use a Phillips screwdriver PH1 to remove the grounding screws of the expansion module.
Step 3 Lift the expansion module out of the control box positioning stud and pull it out to a suitable position. Disassembly is complete.

Note:
When two identical communication expansion modules are mounted at the same time, only the expansion module in the slot with a small label number is functional, while the other expansion module is used for redundancy. For example, when two DP expansion modules are inserted in slot 1 and slot 2 respectively, the DP module in slot 1 is valid.
For other parameter settings of the EC-TX803 PROFIBUS-DP expansion module, see software manuals of the GD880 series products.
