Fusing; Dc Voltage Transients; Grounding The Rv50 Series Gateway Chassis - Sierra Wireless AirLink RV50 Series Hardware User's Manual

AirLink RV50 Series Hardware User Guide
both the gateway and cable vibrate together. The strain relief should be mounted such
that it does not apply additional stress on the power connector, i.e. 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 4.0 A
fast-acting fuse.

DC Voltage Transients

The AirLink RV50 Series gateway has built-in protection against vehicle transients
including engine cranking (down to 5.0 V) and load dump, so there is no need for external
power conditioning circuits. For details, see
