Installation

WARNING
Make sure the instrument that is being installed is in a powered down state
with all cables unplugged. Failure to install an instrument in a discharged
state may cause an electrical shock or death.
CAUTION
Place the hottest equipment (for example, the power supply) at the top of the rack.
Place precision equipment as low as possible in the rack (where temperatures are
cooler).
Follow instructions included with Keithley Instruments equipment for rack mounting.
