Electrical System Connections

Connection to +36V and +48V Systems

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 PVD and any accessory equipment, to
ensure safe and proper operation. Do not make any electrical connections
CAUTION
directly to the chassis of the forklift.
Figure 5 illustrates a wiring diagram for +36 and +48 volt systems. The use of
a DC/DC converter is required to step down the battery voltage for use by the
PDA.
When using any optional equipment caution must be taken to ensure that +36
or +48VDC does not exceed any voltage rating for these devices. Follow all
manufacturer's installation instructions carefully. For any accessories, follow
manufacturer's recommendations for fuse protection.
Some DC/DC converters provide internal Noise Spike/RF filtering. However,
the use of an additional filter is required.
