Battery and Charger Precautions
When installing the CHG-75 battery charger, observe the following precautions:
❒ Do not cut any jumpers when power is applied to the charger
❒ Observe polarity when making connections
❒ Do not connect the Battery Interconnect Cable until instructed
❒ Mounting batteries requires proper mounting hardware. Follow the battery
manufacturer’s installation instructions
❒ Be careful when lifting and handling batteries: batteries are heavy
❒ Batteries, although sealed, contain sulfuric acid which can cause severe burns to
the skin and eyes, and can destroy fabrics. If contact is made with sulfuric acid,
immediately flush the skin or eyes with water for 15 minutes and seek immediate
medical attention
❒ Charging batteries can cause flammable hydrogen gas
