Power supply installation
This chapter describes installation of CCpilot VC in vehicles or other machines. The principle is the
same also for other types of installations.
For connector pinout, see chapter 6 - Connectors.
Before installing the device into a v ehicle or other machinery, carefully read through the instructions
below:
Wire gauge for the supply input shall be dimensioned with respect to cable length, supply
v oltage, maximum allowed voltage drop and maximum current consumption of the device.
o
As a guideline, the recommended minimum power supply cable area is:
0.75 mm
2
(AWG 18)
When connecting the device to a v ehicles or machines battery (or other power source with
high current capabilities), always apply fusing to prevent cable fire in case of short circuit.
o
The fuse shall be located as close to the battery/power source as possible.
o
Fuse rating shall be dimensioned with respect to wire gauge maximum current rating
and inrush current of the load. Refer to chapter 7.1 - Technical data for fuse rating
details.
o
As a guideline, a fuse with 5 -8 A current rating should be used.
The device’s external on/off control signal (multipin connector 1, pin J1-3) should be
connected to the positive supply line via the v ehicles turnkey switch or a separate on/off
switch (see “S2” in schematic below).
o
Remember to apply fusing also to the on/off control signal.
o
Sev eral CCpilot VC devices may be controlled by the same external on/off switch by
joining their external on/off control signals. The current drawn from this signal (when
turned ON) is up to 1.5 mA for each device attached. The fuse rating and wire gauge
shall be dimensioned for the total switch current.
If the v ehicle or machine has a main power switch (see “S1” in schematic below), the device’s
power supply and on/off signal shall be connected after this switch. Observe that this switch
shall not be used for switching the device on/off during normal operation. It is only intended
for disconnecting the battery to prevent draining of the battery during prolonged stalling
intervals of the v ehicle or machine.
