Frame Installation
Overview
• This section provides Grass Valley Video Production Center rack installation
instructions, cooling and power requirements, and chassis and board descriptions for
the GV K-Frame XP Compact Frame.
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 condition. Video Processors Frames
require rear rack support.
Cooling Requirements
The maximum ambient temperature for a GV K-Frame XP 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 otherwise covered. Air intake holes
exist on the front of the Video Processor 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).
All Video Processor 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.
