Meeting Location and Electrical Requirements
The FR6822
+
frame is cooled by forced air that is drawn in from the front and expelled
through the rear. You can stack any number of FR6822
+
frames in a rack as long as you
maintain proper ventilation and remove all obstructions to air flow.
CAUTION
To ensure proper ventilation, keep the front panel of the frame closed during
operation, and install blank back connectors behind empty module slots. The
frame will overheat if you do not observe this precaution.
Ambient temperature should be maintained at between 32°F (0°C) and 113°F (45°C) at a
relative humidity of 10%-90% (non-condensing).

Item Specification
Load Limitations Each FR6822
+
frame can contain two redundant, modular, self-contained power
supply units with standard IEC mains connectors. One PSU can support an entire
frame load. An AC unit requires an independent supply of 100 to 250 V AC, at 47 to
63 Hz. DC units require an independent supply of 36 to 72 V DC.
Voltage
Selection FR6822
+
frames do not have voltage selector switches. Voltage selection is automatic
upon power-up.
