Installation & Safety Instructions
- Disconnect battery / DC main‑power before fuse installation or replacement to prevent short‑circuit hazard.
- Apply correct tightening torque for M8 fasteners; insufficient torque will generate over‑heating under heavy‑current load.
- Do not exceed 800A maximum rated current of this single‑circuit holder.
- Select matched battery‑protection fuse according to actual continuous‑working‑current of the circuit.
- Carry‑out temperature derating assessment for sealed high‑temperature installation compartments.
- Regularly inspect fastener tightness for vehicle / marine vibration‑prone operating environments.
