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 PDA.
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 mobile platform’s positive and negative battery terminals. It is
important to maintain electrical isolation when installing the PMD and any
accessory equipment, to ensure safe and proper operation. Do not make
any electrical connections directly to the chassis of the forklift.
