Installation Guidelines

CRITICAL WARNING: Hazardous voltages are present. All installation and maintenance activities must be performed by qualified personnel with all power sources de-energized and locked out (LOTO). Failure to comply can result in severe injury or death.

1 De-energize System: Before installation, completely disconnect and lock out all incoming power to the control cabinet or panel. Verify the absence of voltage using a properly rated test instrument.
2 Mount the Unit: Securely mount the power supply unit into the designated slot within the SIMATIC S5 rack or chassis. Ensure all mounting hardware is properly tightened to establish a solid mechanical and electrical connection to the backplane.
3 Connect Protective Earth (PE): Connect a dedicated protective earth conductor to the designated PE terminal on the unit. This connection is critical for safety and must be the first wire connected and the last disconnected.
4 Connect Input Power: Connect the main AC or DC input power lines to the corresponding input terminals. Ensure the source voltage matches the specifications on the unit's nameplate.
5 System Verification: After all connections are secure, remove locks and re-energize the system. Check for correct status indicators on the power supply and verify that the 24V DC output is stable and within specification before allowing the PLC to enter RUN mode.
