As a guideline, a slow blows fuse in the range of 100-500 mA for the on/off signal should be
sufficient for most practically usable wire gauge.

Application example
Below is an application example schematic of the
CCpilot VA
power supply connection.
If the system has a main switch for completely disconnecting the battery ( S1 in schematic below), the
device’s power supply and on/off signal shall be connected after the main switch. Observe that this
switch is only intended for disconnecting all system loads to prevent draining of the battery during
prolonged dormant periods and shall
not
be used for starting/shutting down the
CCpilot VA
device on
a regular basis.
By connecting the power supply according to the example above, the
CCpilot VA
device(s) will
automatically start up when the Turnkey switch (S2) is closed and shut down when the switch is
opened.
Note that the on/off behaviour of the
CCpilot VA
described is the default configuration. Its response to
the on/off signal may be disabled or changed by user applications. For example, the signal may be
configured for suspending and resuming the device or the device may be configured to always start
when the power supply is available. See
chapter 4
for more details and configurations available.
