DL405 Base Configurations

DIMENSIONS AND INSTALLATION

It is important to understand the installation requirements for your DL405 system. This will help ensure that the DL405 products operate within their environmental and electrical limits.

• Plan for safety
  The catalog and Web page information should never be used as a replacement for the user manual. The user manual, D4-USER-M, contains important safety information that must be followed. The system installation should comply with all appropriate electrical codes and standards.
  
  
• Base dimensions and mounting orientation
  Use the diagrams provided to make sure the DL405 system can be installed in your application. To ensure proper airflow for cooling purposes, DL405 bases must be mounted horizontally. It is important to check these dimensions against the conditions required for your application. For example, it is recommended that you leave 1.5" depth for ease of access and cable clearance. However, your distance may be greater or less. Also, check the installation guidelines for the recommended cabinet clearances.

Note:
There is a minimum of 2" (50mm) clearance required between the panel door or any devices mounted in the panel door and the nearest DL405 component.

Base Configurations

• Four, six, and eight-slot bases
  The DL405 product family offers four, six, and eight-slot I/O bases.
  
  
• Expansion units
  The expansion units are only necessary when you want to use local expansion. They are installed in the CPU slot of the expansion bases. They appear very similar to CPUs, but they only contain a power supply. One of the most often asked questions for the DL405 family is, “Does the CPU consume an I/O slot?” The answer is no. The CPU has a special slot in the base and does not consume any of the available I/O slots. The same is true for Expansion Units (D4-EX, D4-EXDC and D4-EXDC-2) and the Remote Slave Units (D4-RS). An expansion cable is required to connect each of the expansion bases to the CPU base (D4-EXCBL).
  
  
• D4-450 and –1 bases
  In the past, a DL405 system has been limited to only accepting specialty modules in the local CPU base. The –1 bases must be used with the D4-450 CPU to remove this limitation. The part numbers for the new bases are D4-04B-1, D4-06B-1, and D4-08B-1.
  (Note: you cannot simply add a –1 base to an existing system to gain specialty modules in expansion bases. Instead, you must replace the CPU and all other expansion bases as well.)
  You can add the –1 bases in an existing system, but they are subject to the limitations of the regular bases.
