Ensure that CCpilot V700 is mounted to a smooth, flat surface. Fastening the unit to an uneven
surface may stress the enclosure, damage the outer flange or possibly even flex the circuit
board inside, leading to a premature failure.
4.2.
Connecting to power supply
This chapter describes how the CCpilot V700 is preferably connected to the power supply of
the equipment it is installed in. The principle is the same for vehicular and stationary
installations.
Carefully read through the following sub-chapters. They are critical for designing and adapting
the electrical system of the equipment in which the CCpilot V700 is installed. Connector
pinouts are found in chapter 7.
4.2.1.
Wire gauge
Wire gauge for the power supply should be dimensioned with respect to the total load current,
the cable length required, and the worst-case voltage drop allowed, considering the minimum
operational voltage of the device.
•
Current consumption of the CCpilot V700 device is found in chapter 8.1.
•
The wire gauge for the power supply is recommended to be at least 0.75 mm
2
/AWG 18 for
“normal” loads.
4.2.2.
External fuse
To prevent cable fire in case of short circuit, an external fuse must always be used when
powering the device from a high current capable power source, for example a vehicle battery.
•
The fuse shall be located as close to the battery/power source as practically possible. A
recommendation is to place the fuse at a maximum distance of 15 cm (6 inches) from the
(+) terminal of the source.
•
Fuse rating shall be dimensioned with respect to wire gauge, maximum current
consumption and the inrush current of the device. Refer to chapter 8.1 for fuse rating
details.
•
As a guideline, a slow acting fuse with 2-3 A current rating should be used.
•
Remember to also apply fusing for the on/off control wiring, see chapter 4.2.4.
4.2.3.
External key switch signal
The device’s key switch signal should be connected to the positive supply line via the vehicle’s
ignition key switch.
•
The wire gauge for the key switch signal shall be dimensioned to handle the total switch
current and the fuse type and rating shall be selected to prevent cable fire in case of
cabling short circuit.
•
As a guideline, a slow acting fuse in the range of 100-5000 mA for the key switch signal
should be sufficient for most practically usable wire gauge.
