Model 4299-1 Single-Unit Rack-Mount Kit Installation Instructions
Installation precautions
Observe the following safety precautions while installing instruments.
Turn off instrument power and unplug all cables before installing an instrument in a rack.
Failure to remove power before installation may cause personal injury or death from
electrical shock.
Heat sources should be mounted away from the instrument, cabling, and accessories, with
sufficient space provided between the instrument and heat source for airflow and cooling.
To prevent damaging heat build-up and ensure specified performance, make sure there is adequate
ventilation and airflow around the instrument to ensure proper cooling. Do not cover the ventilation
holes on the sides or back of the instrument. The rear vents and both side vents must be
unobstructed to properly dissipate heat.
Mount precision equipment as low as possible in the rack. Operating temperatures are cooler lower
in the rack.
Prepare the instrument
To remove the handle, mounting ears, and rear feet:
1. Gently pull the handle (1) away from the sides of the instrument case and swing it up or down until the
orientation arrows on the handles line up with the orientation arrows on the mounting ears, as shown in the
following figure.
