Step 4—Connect the Power
The AirLink RV50 Series gateway comes with a 3 meter (10 ft.) DC power cable. You can
also purchase an optional AC adapter.
Note: Electrical installations are potentially dangerous and should be performed by personnel
thoroughly trained in safe electrical wiring procedures.
The RV50 Series gateway supports a voltage range between 7 V and 36 V, but since low
voltage standby mode is enabled by default (as of ALEOS 4.5.2), you must supply greater
than 9 volts at startup.
If you want to operate the gateway at a lower voltage, change the low voltage settings
once the gateway 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 RV50 Series gateway 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 gateway, so
