FR-6804/FR-6804-1 Frames
Overview
The FR-6804(-1) frame is a 2RU unit. It provides a maximum of ten
modules with up to eight outputs per module. The FR-6804(-1) comes
equipped with one power supply unit, the 6804PS(-1), and is pre-wired
for an optional second 6804PS(-1) unit for redundant (standby backup)
power. Also, an external DC power connector is provided if external
power redundancy is needed.
The FR-6804-1 and FR-6804 frames are identical to the FR-6802, except
that the FR-6804-1 provides a General Purpose Interface (GPI) contact
closure for indication of power supply failure when used with a 6804PS-
1 power supply. If the 6804PS-1 is used in the FR-6804, or the 6804PS is
used in the FR-6804-1, the power supply failure indication will not
function.
To reduce the risk of electrical
shock, plug each power supply
cord into branch circuits
employing separate serve
grounds.
The FR-6804 does not provide
this feature with use of either of
the power supplies. It should be
noted that the FR-6802 is not top
or bottom vented.
