9.2.6 Replacing Fuses

When replacing the fuse on the high-voltage interface board or the fuse in the fuse box, use a fuse of the same model, avoid being misled by the parameter screenprint on the fuse box.

380V systems can use both 380V/4A fuse and 500V/4A fuse, while 400V/415V systems can use 500V/4A fuse only.
