5. POWER
TAKE CARE WHEN WIRING INTO ANY VEHICLE. CARRY OUT PRE-INSTLLATION CHECKS TO ENSURE THERE ARE NO PRE-EXISTING FAULTS ON
THE VEHICLE’S DISPLAY. IF YOU FIND A FAULT, DISCUSS WITH THE CLIENT OR tracpoint Support BEFORE CONTINUING.
A source of power should be identified using a multi-meter. Main feeds going to the fuse board are the preferable option. Connect to a permanent positive
supply (10-32V) via a 2 Amp in-line fuse. Cover fuse-holders with tamper proof sticker provided.
Fig 6: Power Connection
It is strongly recommended that power pick up points are chosen that DO NOT form part of an auxiliary supply, such as a cigar lighter or auxiliary power
socket, as these can be compromised by the connection of third party Devices, such as power chargers, inverters, tools etc.
All connections should be soldered, unless using a suitable eyelet terminal on a threaded bolt secured with matching nut on the vehicle.
WHEN SOLDERING, CARE MUST BE TAKEN NOT TO DAMAGE SURROUNDING WIRING WITH HEAT FROM IRON’S EXHAUST.
SOLDER IN WELL-VENTILATED AREAS. SOLDER FUMES MAY BE HARMFUL
6. EARTH
When choosing an earth point, it is advisable to take an earth from a predefined chassis point. There should be no electrical resistance present between the
Device and earth.

7. IGNITION
Ignition feed must be sourced from a point which only comes ‘live’ when the engine is switched on. Fuse with 1 Amp fuse, covered with tamper proof sticker.
To get a true engine running feed, an ignition feed must be sourced that only becomes live when the engine is switched on and is lost when the engine is
switched off again. Alternatively, use Phantom Ignition Sensor supplied. See comments below with reference to the PIS and Fig. 9
IF USING COMPLETE ACCESSORY LOOM (ACCY1056), THE PHANTOM SENSOR (PIS (12V only)) IS ALREADY PRESENT ON THE LOOM. PLEASE
REFER TO SECTION 16, Fig 14 FOR MORE INFORMATION. IGNITION WIRE ON ACCY1056 IS BLUE IN COLOUR
Fig 8: Ignition Feed Connection
In-line Phantom Ignition Sensor (12V ONLY)
The Phantom Ignition Sensor (PIS) is used to simulate an engine running feed when a true engine running feed is not available.
The PIS (12V) is supplied with the trac6140 as a standard component. If using the trac6140 on a 24V installation, do not use the PIS supplied.
In the case of the trac6141, the PIS (12V) is integrated into the ACCY1056 Complete Accessory Loom.
The PIS is not available as part of the trac6142 or its ACCY1075 Complete Accessory Loom.
Note: The term “engine running feed”means there is a voltage (feed) present only when the engine is actually running.
The PIS is a box which connects to the main power line for the Device. Once the engine is switched on in a vehicle, the current and voltage in the vehicle will
rise, as the alternator engages to charge the battery in normal operating mode. This box will sense the difference in voltage and throw an input high on engine
start, simulating that of a true engine running feed.
