7. MAINTENANCE, TROUBLESHOOTING

7.3Replacement of Fuse

The fuse on the power cable protects the equipment from reverse polarity of the ship’s mains and equipment fault. If the fuse blows, find out the cause before replacing it. Use the correct fuse (15A for 12 V device, 7A for 24 V device). Using the wrong fuse will damage the equipment and void the warranty.

CAUTION

Use the proper fuse.

Use of a wrong fuse can cause fire or damage the equipment.
