Connecting the Power Inserter
2.7 Connecting the Power Inserter
Connect the TR2526+ F-Connector to the power inserter, located indoors with the cable
modem. Vecima recommends that the F connectors should be tightened to a maximum
torque of 30 in/lb. A 7/16" torque wrench should be used to prevent over tightening. The
use of excessive torque can cause damage to the transceiver connectors or internal circuitry.
The power inserter has three connections:
• DC POWER - Connect to wall adapter with RG-59 cable with F connectors
• TO MODEM - Connect to cable modem (install modem only after the antenna is
aligned)
• TO TRANSCEIVER - Connect to TR2526+
Ensure that the connection to the TR2526+ is made before plugging in the AC
adapter/power supply (i.e. hook up the power supply last).
Connect the power inserter to the Cable Modem. If the antenna is to be aligned with the
self-install feature, ensure that the power inserter is connected to the Cable Modem, only
after the antenna is aligned.

WARNING! Always unplug the power supply before making or changing connnections to the power
inserter.
CAUTION: The power inserter should be installed as near to the building entrance as possible. If this
is not possible, then a grounding block for the transceiver cable must be installed at the service
entrance.
WARNING! If the power inserter is not connected correctly, the TR2526+ will not operate, and there
is the potential to damage the cable modem.
