1-10 Getting Started
Power-up
Line power connection
Perform the following procedure to connect Model 6514 to line power and turn on the
instrument.
1. Check to be sure the line voltage setting on the power module is correct for the operating
voltage in your area. The line voltage setting is indicated in the window on the power
module (see Figure 1-2). The upside-down 120 setting is for line voltages of 100/
120VAC, and the upside-down 240 setting is for line voltages of 220/240VAC. The pro-
cedure to change the line voltage setting is provided in Section 20.
CAUTION Operating the instrument on an incorrect line voltage may cause damage to
the instrument, possibly voiding the warranty.
2. Before plugging in the power cord, make sure the front panel power switch is in the off
(O) position.
3. 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.
WARNING The power cord supplied with Model 6514 contains a separate ground wire
for use with grounded outlets. When proper connections are made, instru-
ment 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.
4. Turn on the instrument by pressing the front panel power switch to the on (1) position.
Line frequency selection
During the power-up sequence, the selected line frequency setting is displayed. The line fre-
quency setting can be changed from the front panel by holding in the TRIG key during the
power-up sequence. This action toggles between 50 and 60Hz. The command to remotely set
line frequency is listed in Table 1-1.
