Fuse 5A Ignition key
Use at least AWG 20 wires for the battery connection
to the Meter. Maximum allowed wire size is AWG16 for
the screw terminals. It is recommended that a 5A fuse
is used to protect wiring and Meter. The meter itself is
short circuit proof with internal current limitation at
5 - 6 A.
If the Meter is not connected to the ignition switch the
driver must turn off the Meter using its On/Off button to
reduce current consumption.
Smart box connection
Always use the prefabricated cable with molded
connector available from your dealer. There are cables
for connecting directly to a Smart box and for
connecting to a tractor to semi-trailer cable kit.
