Installation67Settings of the cooling fan transformerThe voltage transformer of the cooling fan (T41) is located at the top of the drivemodule.Setting of the auxiliary voltage transformer of the line contactor optionAdjust the setting of the transformer (T1, located in the enclosure extension)according to the input voltage.Installation of optional modules and PCThe optional module (such as fieldbus adapter, I/O extension module and the pulseencoder interface) is inserted in the optional module slot of the RMIO board andfixed with two screws. See the appropriate optional module manual for cableconnections.Cabling of I/O and fieldbus modulesSet according to the supply voltage:380 V, 400 V, 415 V, 440 V, 480 V or 500 V; or525 V, 575 V, 600 V, 660 V or 690 V.Note: No need to set for 230 V units.Set to 220 V if the supply frequency is 60 Hz. (Thevoltage is set to 230 V (50 Hz) at the factory.)ShieldModule2341As short as possibleGrounding wire of the outer shieldStrain relief witha cable tieAlternative to a)a)
