Note: When using a DC power
source (such as a solar cell),
Sierra Wireless recommends
placing a fuse (1-2 Amp) on the
line close to the power source to
protect your power source from
possible surges due to shorts or
other line issues.

Tip: The DC power cable has a white wire lead in addition to the
power positive and negative. This is for a feature not present in the
Raven line modems. In the Raven XE, the white wire lead has no
function and can be ignored.
Warning: Explosion Hazard - Do not disconnect
equipment unless power has been switched off or
the area is known to be non-hazardous.
