Installation Guide
Tools Needed:
- Safety goggles
- Rubber gloves
- Adjustable wrench
- Wire brush
- Voltage tester
Step-by-Step Installation
- Choose Installation Location: Select a well-ventilated, dry location away from sparks, flames, and combustible materials.
- Prepare Battery: Clean battery terminals with wire brush to ensure good electrical connection.
- Connect Charger: Connect red clamp to positive (+) battery terminal and black clamp to negative (-) terminal or grounded metal.
- Power Connection: Plug charger into a properly grounded 120V, 60Hz AC outlet. Do not use extension cords.
- Select Charge Rate: Choose appropriate charge rate based on battery size and condition (2A, 10A, or 50A engine start).
- Monitor Charging: Observe charging process and check battery periodically for excessive heat or gassing.
- Disconnect Properly: Turn charger off before disconnecting clamps - remove negative clamp first, then positive.
