Ensure the cable length from the Ethernet source (host) to the Power Tap (or Power Injector)
and access point does not exceed 100 meters (333 ft). Neither the Power Tap or Power
Injector has an On/Off switch. Each receives power as soon as AC power is applied.
3. For Power Tap installations, have a certified electrician open the Power Tap enclosure, feed
the power cable through the unit’s
LINE AC connector, secure the power cable to the unit’s
three screw termination block and tighten the unit’s LINE AC clamp (by hand) to ensure the
power cable cannot be pulled from the unit and is protected from the elements.
4. For Power Tap installations, attach a ground cable between the EARTH GROUND
connector (on the back of the unit) to a suitable earth ground connection as defined by your
local electrical code.
5. Verify all cable connections are complete before supplying power to the access point.
