1) Follow all General Guidelines as specified on page 6.
2) It is strongly recommended to keep Zonar electrical connections
outside "master kill" circuitry. Failing to do so may lead to
inaccurate data (See caution notice this page).
3) Connecting V3R to negative/ground side "master kill" circuits
(commonly found on construction equipment) may lead to false
idle times.
4) All power leads must be connected to the vehicle’s protected
circuitry (e.g. fuse panel, circuit breaker panel, protected circuits).
Never electrically connect Zonar equipment to unprotected
circuits (e.g. directly to battery).
5) It is also required that all power leads (Red and White leads),
be protected with a 3 to 5 amp fuse and inline fuse holder
(included) for optimal system protection.
6) Electrical fuses should be installed as close as possible to the
source of power.
7) Power Bundle wiring – 4 Pin, 3 wires
A. Red – Constant DC (+8 VDC - +30 VDC), dependent
on system type
B. Black – Ground must be less than 1 ohm (measure from
4 Pin connector to chassis attachment point)
C. White - Switched Power
The White wire must be connected to a power source that
is active only when the engine is running or the system
will not track idle time properly
i. Engine running (+8 VDC to +30 VDC)
ii. Engine NOT running (0 VDC)
iii. Engine NOT running (key position ACC or Accessory)
Mode (0 VDC)

21’ Power Cable
If power cabling is not connected and powered as
described in paragraph 7, one or more of the following
may occur, contact Zonar for additional info:
A. Cold Start flags (an indicator that a unit lost and regained
constant power)
B. Inaccurate idle and stop times
C. Inaccurate hour meter data
D. Inaccurate mileage data
E. Missing path data
F.
Straight line data segments
Please contact the vehicle manufacturer for any vehicle
specific electrical questions.
