The TS-8820 can be powered via PoE or direct DC voltage input to the terminal block connectors. If PoE is not used, power must be supplied on terminal block P6.
1 DC via Terminal Blocks
Direct power input can be applied to the P6 terminal block. There are three terminals for power and three for a ground connection. Each of the three sets of terminals are electrically connected together internally in the TS-8820. Operational range of the TS-8820 is +10 VDC to +30 VDC on these inputs. Supply an external ground on terminal 10, 11, and/or 12. Supply +10 V to +30 V on terminal 7, 8, and/or 9.
2 802.3af PoE
The TS-8820 is IEEE 802.3af PoE compliant. This allows the whole unit to be powered directly from a PoE sourcing device.
When powered via PoE, +24 VDC is made available on the P6 terminal block power terminals. Ensure that the total power draw of the system does not exceed the limits defined by IEEE 802.3af and that power is not also supplied to the TS-8820 on these pins!
