Follow these guidelines when you handle this equipment: • Touch a grounded object to discharge potential static. • Wear an approved grounding wriststrap. • Do not touch connectors or pins on component boards. • Do not touch circuit components inside the equipment.
DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O Power Supply ATTENTION 1790D-0V16, 1790D-0B16 To comply with the CE Low Voltage Directive (LVD), the DeviceNet network and outputs must be powered from a source compliant with Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV). To comply with UL restrictions, the DeviceNet network and outputs must be powered from a source compliant with Class 2 or Limited Voltage/Current.
DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O 5 North American Hazardous Location Approval The following information applies when operating this equipment in hazardous locations. Informations sur l’utilisation de cet équipement en environnements dangereux. Products marked CL I, DIV 2, GP A, B, C, D are suitable for use in Class I Division 2 Groups A, B, C, D, hazardous locations and nonhazardous locations only.
DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O Before You Begin Read this section about CompactBlock LDX I/O block requirements. Current functions of CompactBlock LDX I/O blocks require the current, modular electronic data sheet (EDS) file for RSNetWorx for DeviceNet software, version 3.0 or later. These files are available online at www.ab.com/networks/eds/. EDS files for blocks with matching catalog numbers for both D-Shell and terminal block versions are the same.
DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O 7 Set the Node Address When setting the node address on the base block, note that each base block comes with its internal program set for node address 63. To reset the node address, adjust the switches on the front of the base block. The two switches are most significant digit (MSD) and least significant digit (LSD). You can set switches between 00 and 63. The base block reads the rotary switches only when power is applied.
DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O Mount the Base Block Mount the base block to a panel or DIN rail. We recommend that you ground the panel or DIN rail before mounting the block. IMPORTANT The analog base module can accommodate a maximum of two digital expansion modules. Mount on a Panel For panel mounting, use these steps. 95 mm (3.74 in.) 41 mm (1.6 in.) Expansion Cover 44153 1 . Place the block against the panel where you want it mounted. 2.
DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O 9 4. Remove the block and drill two holes in the panel to accommodate each of the mounting screws. 5. Replace the block on the panel and place a screw through each of the two mounting holes. 6. Tighten the screws until the block is firmly in place. Mount on DIN Rail For DIN-rail mounting, use these steps. 1 . Hook the top slot of the base block over the DIN rail. Locking Lever 44154 2.
DeviceNet Digital Base D-Shell Block CompactBlock LDX I/O Beginning with the base block, mount your expansion block either horizontally or vertically. Horizontal Mounting Vertical Mounting The longer expansion cable (1790-15CMCBL) provides for up to 7 cm (2.76 in.) of space in between blocks. 44155 • To mount horizontally (left to right), add the expansion block in an end-to-end configuration.
