Installation Guidelines

CRITICAL WARNING: Hazardous voltages may be present. Installation must be performed by qualified personnel only. Ensure the system is de-energized and locked out/tagged out (LOTO) before beginning any work. Failure to comply can result in severe injury or death.

1 De-energize System: Isolate and disconnect all power sources from the SIMATIC S5 rack. Verify zero energy state with a calibrated multimeter before proceeding.
2 Inspect Module: Before installation, visually inspect the 6ES5955-3NC41 module for any signs of physical damage that may have occurred during shipping or handling.
3 Install Module: Align the module with the card guides in the designated power supply slot of the S5 chassis. Slide the module firmly into place until the connectors are fully seated on the backplane.
4 Secure Module: Engage and tighten the module's retaining screws to secure it firmly within the chassis. This ensures proper electrical connection and resistance to vibration.
5 Connect Input Power: Connect the 24V DC input power wiring to the appropriate terminals on the module's front panel. Ensure correct polarity is observed. Verify that all connections are secure.
6 System Re-energization: After removing all tools and personnel from the enclosure, close the cabinet doors. Remove the LOTO device and re-apply power to the system. Observe the module's status indicators to confirm correct operation.
