30 Mounting WAGO I/O-SYSTEM 750753-454 2AI 4-20mA Diff.ManualVersion 1.1.05.3.1 CodingCoding using small plastic pins and sockets facilitates mating of the module withthe appropriate connector.1. Insert the pin into the socket.Figure 12: Assembling the Coding Fingers2. Position the assembled coding fingers in the I/O module. Due to its design,each coding finger allows four different coding options (i.e.; 16 differentoptions using two coding fingers).Figure 13: Inserting the Coding Fingers3. Place the connector onto the I/O module.Figure 14: Plugging the Connector into Place
