Unlike active bus termination units, this module does not terminate communications signals but instead acts as a bridge to physically secure the rack structure on long DIN rails. Note that if you are designing a system where heat dissipation is critical, placing space units adjacent to high-current analog modules can optimize convective airflow pathways inside the panel.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem;\"\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eWhile this spacer is mechanically identical to standard I\/O cards, it must not be assigned any I\/O addresses in the PLC configuration software (CX-Programmer or Sysmac Studio). The software configuration should simply skip the physical slot position where the space unit is mounted. Ensure that you do not force active CPU-bus communication cycles to an empty slot, as this may result in rack configuration discrepancies or localized bus faults.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem; border-radius: 4px;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c; display: block; margin-bottom: 0.5rem;\"\u003eCRITICAL WARNING\u003c\/strong\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0;\"\u003eAlways isolate the main control panel power supply before mounting, unmounting, or sliding modules on the CJ-series rack.
