4. Setup and Installation

The Xantrex PROwatt SW Auto Transfer Switch is designed for straightforward installation. It features clearly labeled wiring terminals for connecting your AC power sources and loads. Ensure all power sources are disconnected before beginning installation.

4.1 Product Overview

4.2 Wiring Connections

The transfer switch manages two AC inputs (Utility/Shore Power and Inverter/Generator) and one AC output (Load). The unit automatically switches to the available live source.

• AC Input 1 (Inverter/Generator): Connect the hot (black), neutral (white), and ground (green) wires from your inverter or generator to the designated terminals.
• AC Input 2 (Utility/Shore Power): Connect the hot (black), neutral (white), and ground (green) wires from your utility or shore power source to the designated terminals.
• AC Output (Load): Connect the hot (black), neutral (white), and ground (green) wires leading to your AC loads (e.g., electrical panel) to the designated terminals.

Refer to the diagram on the product label for specific wiring configurations. Ensure all connections are secure and properly insulated.

5. Operating Instructions

The Xantrex PROwatt SW Auto Transfer Switch operates automatically. When multiple AC power sources are connected, the switch will prioritize and transfer the load to the designated primary source (typically utility/shore power) if available. If the primary source is lost, it will automatically switch to the secondary source (inverter/generator) if it is active. When the primary source returns, the switch will automatically transfer the load back.

• Ensure all power sources are properly connected and functioning.
• The transfer time is typically very fast, ensuring minimal interruption to your connected loads.

6. Maintenance

The Xantrex PROwatt SW Auto Transfer Switch requires minimal maintenance. Regular inspection is recommended to ensure optimal performance and safety.

• Periodic Inspection: Annually, inspect all wiring connections to ensure they are tight and free from corrosion.
• Cleaning: Keep the exterior of the switch clean and free from dust and debris. Use a dry cloth for cleaning. Do not use liquid cleaners.
• Environmental Conditions: Ensure the switch is installed in a dry, well-ventilated area, protected from extreme temperatures and direct moisture.

7. Troubleshooting

If you experience issues with your Xantrex PROwatt SW Auto Transfer Switch, consider the following troubleshooting steps:

• No Power to Loads:
  • Check if both AC input sources (utility/shore power and inverter/generator) are active.
  • Verify all wiring connections are secure and correct.
  • Check circuit breakers or fuses in your power system.
• Switch Not Transferring:
  • Ensure the primary power source is truly lost or the secondary source is fully active.
  • Confirm the switch is receiving adequate voltage from the active source.
• Overheating:
  • Ensure the load connected does not exceed the maximum amperage rating of the switch.
  • Verify adequate ventilation around the unit.

If problems persist after attempting these steps, contact a qualified electrician or Xantrex customer support.
