Installation Guidelines

• Ensure the power supply is disconnected from the rack before inserting or removing any modules.
• Mount the chassis securely to a flat, vibration-dampened surface to maintain backplane alignment.
• Verify that the grounding lugs are properly bonded to the control cabinet's earth ground to protect against electromagnetic interference.
• Maintain adequate clearance around the unit to allow for natural convection cooling and to prevent overheating.
• Handle all internal bus connectors with care to prevent pin damage during module installation.

FAQ

Is this rack compatible with other Siemens S5 series?
The 6ES5701-0LA11 is specifically designed for the S5-115U series. Please consult your system documentation to ensure compatibility with your specific controller model.

Does this unit require an external power supply?
The rack itself acts as a passive backplane. Power is typically distributed through the system's power supply module installed within the rack or via the central controller interface.
