Frames Installation
General Rack Mounting Instructions
Weight Distribution
Make sure that you mount the unit in the rack so that it is evenly balanced
to prevent damage to the frame and to avoid creating a hazardous condi-
tion. Karrera Frames require rear rack support.
Cooling Requirements
The maximum ambient temperature for a Karrera chassis is 40-degrees C
(104-degrees F) monitored at the air intake. Installing the frame in a closed
or multi-unit rack assembly together with other units could increase the
maximum ambient temperature for this unit.
Make sure you install the frame to allow for cooling airflow. When the unit
is installed in a rack, ventilation openings should not be blocked or other-
wise covered. Air intake holes exist on the right side of the Karrera frame
(as you face the frame front) and air exhaust holes are on the left.
Power Connections
When connecting the unit to the supply circuit be sure that the supply
circuit of the rack is not overloaded. The unit must be well-grounded. The
safety ground is accomplished via the third wire in the AC line cord(s). The
rear panel ground lug is available for an optional ground.
All Karrera Frame power supplies are 100V-240V AC +/-10% autorange,
power factor corrected. Each power supply has its own line IEC line cord.
Connecting each line cord to a separate AC circuit is recommended.
