🧱 Installation & Mounting

To ensure safe and effective operation:

Mount on a non-combustible surface (metal, brick, or concrete).

Leave at least 3 inches (8 cm) clearance around the cooling fan.

Preferred Mounting Positions:

Horizontally with the fan facing upward

Vertically with AC/DC cables facing up or down

Side-mounted with cables facing left or right

Avoid: Mounting with the fan facing downward.

⚠️ Safety Precautions

Always use a grounded AC outlet.

Charge only compatible LiFePO₄ batteries matching the rated voltage and capacity.

Disconnect from AC power after use.

Ensure adequate ventilation when charging indoors.

Avoid sparks, open flames, or smoking near the battery.

Charger surface may become hot during operation — do not touch.

Only qualified technicians should service or re-program the unit.
