2.7.5 Mains Connection

The input supply range for the PIDU Plus is 90V-264V AC, 47-63Hz. Mains connection to the
PIDU Plus is made using a standard "figure of eight" mains lead as shown in Figure 6.

Redundancy and Alternative Powering Configurations

The PTP 500 Series Bridge can be powered from an external DC source and can be provided
with power supply redundancy as follows:
•
External DC supply only (Figure 6): This configuration is for use where there is no mains
supply.
•
External DC supply and AC supply (Figure 7): This configuration provides redundancy
through the use of mains and DC supply.
•
External DC supply and redundant AC Supply (Figure 8): This configuration guards
against mains failure and failure of the DC output of single PIDU Plus.
NOTE
The use of DC supplies of less than 55v will reduce the usable distance between the
PIDU Plus and ODU.
CAUTION
The maximum distance from the ODU to the connected network equipment is
100 m (330 ft) when using 100BaseT.
