How It Works
- The SF5000 stores electrical energy and releases short, high-voltage pulses at set intervals along the live wire.
- When contact is made between the live wire and ground, a safe but effective shock is delivered.
- The system operates on a pulse principle, meaning it is non-lethal but highly effective for deterrence.
Installation Guidelines
- Mount the energizer in a dry, shaded location with good ventilation.
- Use proper earthing – at least 3 galvanized earth rods spaced apart in moist soil.
- Install high-quality insulators to prevent leakage.
- Use approved warning signs along the fence.
- Keep vegetation clear from the live wires.
Benefits
- Reliable security for property and livestock.
- Energy-efficient operation with minimal maintenance.
- Durable construction for long service life.
- Adaptable for both rural and urban applications.
Safety & Compliance
Always follow the installation manual and relevant local regulations. The SF5000 is designed to deliver short pulses that deter without causing lasting harm. Use visible warning signs and ensure a proper earthing system.
