Important User Information Because of the variety of uses for the products described in this publication, those responsible for the application and use of these products must satisfy themselves that all necessary steps have been taken to assure that each application and use meets all performance and safety requirements, including any applicable laws, regulations, codes and standards.
ATTENTION Identifies information about practices or circumstances that can lead to personal injury or death, property damage, or economic loss. ! IMPORTANT ATTENTION ! Identifies information that is critical for successful application and understanding of the product. Preventing Electrostatic Discharge This equipment is sensitive to electrostatic discharge, which can cause internal damage and affect normal operation.
ATTENTION ! Environment and Enclosure This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage Category II applications (as defined in IEC publication 60664-1), at altitudes up to 2000 meters without derating. This equipment is considered Group 1, Class A industrial equipment according to IEC/CISPR Publication 11.
Installing CompactBlock LDX I/O Follow these steps to install the block: 1. Set the node address on the base block. 2. Mount the base block. 3. Mount the optional expansion blocks. 4. Wire the terminal blocks. 5. Connect the DeviceNet cable. These steps are explained in detail in the following procedures. Set the Node Address on the Base Block 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 block.
Mount the Base Block You can 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 discrete expansion modules. WARNING ! When used in a Class I, Division 2, hazardous location, this equipment must be mounted in a suitable enclosure with the proper wiring method that complies with the governing electrical codes. Panel Mounting 1.
5. Replace the block on the panel and place a screw through each of the two mounting holes. Tighten the screws until the block is firmly in place. 95 mm 3.74 in 41 mm 1.6 in k LDX CompactBloc 1790-16BVOX EXPANSION UNIT 16 INPUTS-DCPOW ER Expansion Cover 7 7 0 0 DIN Rail Mounting 1. Hook the top slot of the block over the DIN Rail. 2. Pull down on the locking lever while pressing the block against the rail. f Locking Lever 3.
Mount the Optional Expansion Blocks Mount the expansion block by connecting it to a previously-installed CompactBlock LDX I/O base or expansion block. Beginning with the base block, you can mount your expansion blocks either horizontally or vertically: • horizontally (left to right) - add expansion blocks in an end-to-end configuration • vertically (up or down) - add expansion blocks either up or down in a back-to-back configuration.

Connect the DeviceNet Cable Follow these procedures when connecting the DeviceNet cable to the base block. The required DeviceNet connector is not supplied with the block; you must purchase it separately.
Once you have properly wired the drop line to the connector, attach the connector to the block. If applicable, use the locking screws on the connector to fasten it to the block.
