Power
Ground
The unit must be connected to earth ground:
1.
Install a #6 ring lug on the incoming ground wire.
2.
Secure the ground conductor to the ground stud, located in the upper right corner of the housing.
PoE (Power over Ethernet)
The device can be powered from the network cable if the speaker output requirement is less than 8 watts.
PoE works across standard network cabling (i.e. Cat5) to supply power directly from the data ports where
the device is connected.
Connect the LAN cable (Category 5 or better UTP cable) to the RJ45 jack, located on the underside of the
VoIP interface PCBA (see Figure 4).
Local Power
The device requires a 120/240 V ac power source if the speaker output requirement is greater than 8
watts.
1.
Install spade lugs on the power line conductors.
2.
Connect the power conductors to terminal block
TB101
, located in the upper right corner of the
housing (see Figure 4).
