exposure to an electrical shock that could result in personal injury or death.

Step 1: Prepare the instrument
Remove both front and rear feet from the instrument by pulling out the rubber feet and then removing the
screws underneath.
NOTE
Do not reinstall the feet mounting screws. Save all parts removed for future bench-top use of the
instrument.

WARNING When rack-mounting restricts access to the main power cord, provide a separate main
power disconnect device. This device must be located in close proximity to the
equipment and within easy reach of the operator.
NOTE
Although the following steps may be completed by one person, two people are recommended.
1. Slide unit into the rack by aligning both 2602-334 rear rack-mount brackets with the associated
rack-mount extension arms (see Figure 3).
