Physical Characteristics and Installation
This filler module weighs approximately 0.12 kg for lightweight handling. Its dimensions measure 250 mm x 25 mm x 40 mm for standard S5 single-width slots. First, slide the 6ES5756-0AA11 into any empty rack position. Then, press firmly until the retaining clips engage the chassis rails. Finally, verify the module sits flush with neighboring I/O modules. The light gray color matches the standard SIMATIC S5 aesthetic.
Purpose and Benefits
The 6ES5756-0AA11 covers unused slots to improve airflow distribution. Open slots can disrupt cooling paths inside the PLC rack. This filler also prevents dust accumulation on backplane connectors. Consequently, the module protects unused contacts from oxidation. The plastic construction meets UL94 V-0 flammability standards for safety.
Compatibility and Usage Guidelines
This filler module works with all S5 rack types including 115U, 135U, and 155U. The 6ES5756-0AA11 does not contain any electronic components or wiring. You do not need to connect any power or signal cables. Always install fillers in every unused rack slot for proper certification. Remove the filler if you add functional modules in the future.
