The LX60 supports an operating voltage of 7 V–36 V, but because low voltage standby
mode is enabled by default, you must supply more than 9 V at startup.
If you want to operate the router at a lower voltage, you can change the low voltage
standby settings once the router is up and running. For more information, refer to the
ALEOS Software Configuration User Guide (Services chapter).

Cable Strain Relief

Sierra Wireless recommends using cable strain relief for installations in high-vibration
environments.
Place the cable strain relief within 200 mm (8 in.) of the LX60 to reduce the mass of cable
supported by the power connector under vibration. Ideally, the strain relief mounting for
the DC cable should be attached to the same object as the LX60, so both the router and
cable vibrate together. The strain relief should be mounted such that it does not apply
additional stress on the power connector. The cable should not be taut and should not pull
the power connector at an angle.

Fusing

For DC installations, Sierra Wireless recommends fusing the power input using a 4 A, fast
blow fuse on the V line, recommended to have no more than ±10% de-rating over the
in
operating temperature range.

DC Voltage Transients

The AirLink LX60 has built-in protection against vehicle transients including engine
cranking (down to 5.0 V) and suppressed 12 V load dump, so there is no need for external
power conditioning circuits. For details, see Industry Certification for Vehicles on page 37.
