Power and grounding specifications
The following section outlines the power and grounding specifications
DC input voltage range
The operational input voltage range for the OME6130 is -40 V dc to -57.5 V
dc with DC feed. The OME6130 is not damaged when an input voltage of
correct polarity, with a value between zero and -40 V dc (minimum voltage),
is applied for any period of time. The system is not damaged by a reversed
polarity voltage supply, for example, zero to +57.5 V dc (the system does not
function with a reversed polarity supply).
The OME6130 automatically recovers when the input voltage returns to a
value exceeding the minimum voltage within an acceptable period of time and
without any manual intervention.
The OME6130 meets the specifications listed in Table 7-36 .
