2 PB50 and PW50 Forklift Power Supply Installation Guide
Understanding the DC Power Supply Kit
The DC power supply kits include these items:
• Power supply
• Power supply input cable, 2.44 m (8 feet)
• Fused power cable, 46 cm (18 inch)
• #10 terminal ring
• 3AB, 20A/250 Vx fuse for 12 V installations
• Insulated quick-connect tabs (2)
The power supply provides 12 Vx output that is filtered and
regulated. It also provides over-current, over-voltage, over-
temperature, and shorted-output protection.
Installation Guidelines
The installer should be familiar with the brands and models of
equipment where this kit is installed. They should also be trained
and experienced in forklift electrical systems.
The installer must follow these guidelines and the installation
procedures as well as those of the lift manufacturer to ensure a
safe and reliable installation.
• Power supply must be securely mounted.
• Mounting surface must be sturdy.
• Mounting surface must provide power supply heat sink.
• Fuse must be close to vehicle power source and be in line with
Intermec equipment only.
• Keep cables as short as possible, and secure them at least every
46 cm (18 inch).
Installation must not violate the forklift manufacturer’s
requirements and should be done by trained professionals.
Chapter 2 details the step-by-step procedure that you will follow
