Check to see that the line voltage indicated in the window of the fuse holder assem-
bly (Figure 1-4) is correct for the operating voltage in your area. If not, refer to the
next procedure, "Setting line voltage and replacing fuse," page
Operating the instrument on an incorrect line voltage may cause dam-
age to the instrument, possibly voiding the warranty.
Before plugging in the power cord, make sure that the front panel power switch is
in the off (O) position.
Connect the female end of the supplied power cord to the AC receptacle on the rear
panel. Connect the other end of the power cord to a grounded AC outlet.
The power cord supplied with the Model 2750 contains a separate
ground wire for use with grounded outlets. When proper connections
are made, instrument chassis is connected to power line ground
through the ground wire in the power cord. Failure to use a grounded
outlet may result in personal injury or death due to electric shock.
Turn on the instrument by pressing the front panel power switch to the on (I)
position.
