- Verify that the input voltage matches the selected range (115V or 230V) before applying power.
- Use appropriate wire gauges for the load requirements and ensure all terminal connections are tightened to the specified torque.
- Always disconnect the main power supply before performing any wiring, maintenance, or module replacement.
- Ensure the unit is properly grounded to the cabinet chassis to minimize electromagnetic interference (EMI).
FAQ
Is this power supply suitable for standard 24V control circuits?
The 3RX9306-1AA00 provides both a 30V output specifically for the AS-Interface bus and a 24V auxiliary output. The 24V output can be used for secondary control devices, but the 30V output must be reserved for the AS-i network components.
What is the primary function of this module?
Its primary function is to provide the regulated 30V DC power required for AS-Interface communication and to power connected field devices, ensuring the network operates within the required voltage tolerances.
