Installation Notes

• Fix the metal profile to the cabinet frame or back panel through the four 6.35 mm mounting holes using appropriate fasteners.
• Terminate the primary 24 V DC power cables securely into the designated M5 power rail holes (+24V and 0V) observing correct torque specifications.
• Connect module and shield grounds directly to the 16-point ground rail to establish proper instrumentation earth.
• Ensure the plastic cover plate is snapped into its correct protective alignment before energizing the 40 A power supply rail.
