Frame Cooling
The equipment is designed to operate in an ambient temperature range of 32° F
– 122° F (0° C – 50° C). No special cooling arrangements are necessary, but you
should take steps to prevent excessive ambient heat rise in closed, unventilated
equipment racks.
Power Consumption
The FR-881 mounting frame accepts one 882PS power supply while the FR-883
frame accepts one 884PS power supply. The FR-881/883 frame power
consumption is nominally 25VA.
The FR-882 mounting frame accepts one 882PS power supply while the FR-884
frame accepts one 884PS power supply. Both frames are prewired to accept a
second optional power supply for power backup. Their power consumption is
nominally 65VA. It should be pointed out that a fully loaded frame will operate
with a single power supply. However, it is recommended that a second optional
power supply be included for cooler operation and power redundancy.
Caution
To prevent electric shock, do not
use this (polarized) plug with an
extension cord, receptacle or
other outlet, unless the blades
can be fully inserted to prevent
blade exposure.
