# Installation of Add-On Cards



1. The 8" and 10" Panels have two Add-On ports located under the cover on the back of the units.

2. After the appropriate Add-On module (KNX, Modbus, INELS, VRF) is selected and installed into the designated ports, the cable connections are made to the Add-On via the black and blue terminals. Subsequently, during the online programming phase or while creating a template for future use, the Add-On type is selected from the "Device" menu and integrated into the system configuration.
