Installation & Mounting

Recommended Mounting Orientations:

Horizontally flat with the fan/handle facing upward

Vertically with AC/DC cords facing up or down

Side-mounted with cords facing left or right

Avoid:

Mounting with the fan facing downward

Mounting Surface:

Mount only on non-combustible surfaces (metal, brick, or concrete)

Ensure at least 3 inches (≈8 cm) of clearance around the cooling fan for ventilation

Safety Precautions

Always connect to a grounded AC outlet

Only charge the specified type, voltage, and capacity of battery

Disconnect from AC power after charging

Keep in a well-ventilated area; avoid sparks, smoking, or open flames near batteries

Surface temperature may become hot—avoid direct contact

Only qualified technicians should service or program the charger
