Installation and Maintenance Tips

1. Installation:

   • Use stranded copper wires (18 – 22 AWG) for input/output connections.
   • Ground the module to prevent electrostatic discharge.

2. Troubleshooting:

   • Check the LED indicator: green = normal operation, red = fault.
   • Replace the module if output voltage deviates by more than ±10%.

3. Safety:

   • Disconnect power before replacing the module.
   • Follow NEC Article 725 for low – voltage power systems.
