ATTENTION!
Study thoroughly the textual wire tagging! The manufacturer keeps the right
to change the colors of the wires.
The DUT-E housing is electrically connected with the "minus" of DUT-E (brown wire
harness).
The mounting plate made of dielectric plastic material provides electrical insulation of the
DUT-E casing from the vehicle casing (of the tank).
ATTENTION!
Signal cable is
strongly recommended
to stack together with the standard
wiring of the vehicle and mandatory to fix its position by means of tie-laps every 0.5 m.
(see Fig. 16).

During the set-up of the recording and display devices it is necessary to make a setting
"DUT-E readings do not depend on the voltage of on-board power system" (if such setting
available).
ATTENTION!
Connection of the DUT-E to the on-board power system and "ground" is
carried out in the same places where the recording and display devices are connected.
After installation and connection of DUT-E you should calibrate the tank (See Appendix 2).
