EV Installations
The negative of the Link 10's power supply must be common to the nega-
tive of the battery (motive pack) which you are measuring. This may pose
difficulty if your electric vehicle uses an "unbonded" or "floating" (no
connection to the chassis) motive pack and a "bonded" (connected to the
chassis) accessory battery. In these instances, the use of a DC-DC con-
verter, or a separate battery with a common negative with the motive
battery is required. This device provides power for the Link 10 without
electrically connecting the motive battery negative to the chassis. The
diagram shown is for a typical DC-DC converter. If you use a different
DC-DC converter, the pin-out may be different:
DC-DC Converter pin outs vary.
