Connection to +24V, +36V and +48V Systems
Figure 5 illustrates a wiring diagram for +24, +36 and +48 volt systems. The
use of a DC/DC converter is required to step down the battery voltage for use
by the terminal.
When using any optional equipment caution must be taken to ensure that
+24, +36 or +48VDC does not exceed any voltage rating for these devices. Fol-
low all manufacturer's installation instructions carefully.
Some DC/DC converters provide internal Noise Spike/RF filtering. The use
of an additional filter is optional.

CAUTION
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
directly to the chassis of the forklift.
