Chapter 2 - Installing the Forklift Power Supply Note: Although you can shorten the input power cable if necessary, you should not extend the cable on 12V or lower systems. On higher voltage systems, keep extensions to a minimum and use a wire of equivalent or lower gauge (larger diameter). Keep the cable as short as possible. You should take these lengths and the intended location of your electronic equipment into consideration when choosing a mounting location for the power supply. The mounting surface location must provide 838 to 1032 square cm (130 to 160 square inches) of metallic surface to sink heat generated by the power supply. This metallic mounting surface may be connected to, or actually part of, the forklift chassis as long as the chassis is not electrically connected to the battery negative or positive. Side-Mount Battery With View of Negative (-) and Positive (+) Direct Versus Isolation Mounting on the Lift Chassis Previously, the power supply was placed directly on the lift chassis. Direct mounting provides both an adequate heat sink and prevents static charge buildup between the metal of the power supply, the printer, and the lift chassis. Directly mounting the power supply is the most straightforward installation method. This installation is also preferred when there is little risk for other forklift accessory devices making electrical contact with the forklift chassis. 12 Forklift Power Supply Installation Guide
