Note: Before you install
the Raven XE in its final
location, be sure to cover
all exposed wiring.
You can purchase an optional I/O Power Cable for the Raven XE which can be
used to attach devices to the combination I/O port and power connector. The
harness has pre-wired leads to allow you to customize your own connections. The
wires are paired and color-coded.
Warning: Risk of electric shock: Only use the supply voltages listed in this user guide.
