Chapter 1 - Introduction Using the Inline Fuse A snap-twist inline fuse holder is furnished as part of this kit. It must be connected as close as possible (electrically and physically) to the forklift power source. It provides catastrophic failure, short-circuit protection for the entire input power cable and the power supply input. The fuse holder contains a 3AB, 20 A/250 Vx (.25 inch x 1.25 inch) fast-blow fuse recommended for installations with 12 V automotive batteries. For other vehicle battery voltages, please refer to the table below. These alternate fuses are not provided with the kit and must be obtained separately. In general, smaller fuse ratings offer faster acting protection. Note: If your fuse fails, diagnose the problem and then correct it before replacing the fuse with the exact same size and type you are replacing. Recommended Fuse Values Lift Voltage 12V 24V 36V 48V Fuse Ratings Description 20A Fast-blow (ships with power supply) 10A Slow-blow, maximum fuse value 6A Slow-blow, maximum fuse value 5A Slow-blow, maximum fuse value Do not replace the fuse with larger fuse values than recommended. Use of a larger fuse may result in damage to equipment. Forklift Power Supply Installation Guide 5
