Electrical System Connections; Connection To +12V And +24V Systems - PSC Falcon 4220 Installation Manual

Electrical Considerations

Electrical System Connections

This section covers electrical connection to +12V, +24V, +36V and +48V sys-
tems.
Proper installation requires that source power connections be made directly to
the vehicle's positive and negative battery terminals. It is important to maintain
electrical isolation when installing the powered vehicle dock and any accessory
equipment, to ensure safe and proper operation. Do not make any electrical
CAUTION
connections directly to the chassis of the forklift.

Connection to +12V and +24V Systems

Figure 4 illustrates a typical wiring connection for a +12 volt and +24 volt sys-
tem. The input voltage operating range of the dock will allow direct connec-
tion to the battery terminals. However, the use of a 5-Amp fuse is required (as
shown in Figure 4), and use of a Noise Spike/RF filter is required.
Accessory equipment may also be required depending on your application,
Refer to Table 1 on page 2-7. For each accessory, read and follow the manufac-
turer's installation instructions carefully.
