To ensure the safe operation of the HP-AHP20SA series inverter/charger, follow these guidelines:

General Precautions:

• Never install in a sealed enclosure with flooded batteries to prevent corrosion from battery fumes.
• Ensure proper ventilation; do not install in confined, harsh environments (e.g., humid, salty, corrosion, greasy, flammable areas).
• Disconnect all switches and breakers before wiring.
• Use tight connections and cable clamps to secure and stabilize cables.
• Do not open or touch internal components immediately after use; wait ten minutes to allow cooling.

Installation and Wiring:

• Follow the correct installation steps, especially when handling batteries.
• Maintain sufficient clearance around the inverter/charger for heat dissipation.
• Adhere to the recommended order for connecting components: Ground > Battery > Load > PV > Utility/Generator > Optional Accessories.
• Choose appropriate wire and breaker sizes based on the model specifications and installation distances.

Operational Safety:

• Avoid electric shock risks by correctly connecting leads and ensuring ground safety.
• If using in areas with frequent lightning, install an external surge arrester.
• For generator connections, test beforehand due to varied output conditions.

Upon initial startup, double-check wire connections and proceed with setting parameters as per the manual.
