SAFETY AND PREPARATION FOR USE
******CAUTION******
This instrument may be damaged if it is
operated with the LINE VOLTAGE
SELECTOR set for the wrong ac line voltage
or if the wrong fuse is installed.
LINE VOLTAGE SELECTION
The DG535 operates from a 100V, 120V,
220V or 240V (50 or 60 Hz) ac power source.
Before applying a power source, verify that
the line voltage selector card (located in the
rear panel power entry module) is in the
correct position. The selected voltage may be
seen through the clear window by viewing the
power entry module from below.
To change the line voltage selection, remove
the line cord, slide the window to the right,
and pull the "fuse pull" lever out. Verify that
the correct fuse is installed for the ac line
voltage: 1 Amp for 100 or 120V, and 1/2 Amp
for 220 or 240V. Pull out the line voltage
selector card with a pair of needle nose pliers,
and insert it with the correct line voltage
facing the bottom of the instrument and
towards the line cord. Verify that the correct
line voltage can be seen through the slot that is
just above thefuse holder. Push the fuse holder
back in, and install the correct fuse. Slide the
window to the left, and replace the line cord.
LINE CORD
The DG535 uses a three wire power cord for
connection to the power source and to a
protective ground. The exposed metal parts of
the instrument are connected to the outlet
ground: to protect against electrical shock,
always use an outlet which has a properly
connected protective ground.
To avoid shock or injury do not remove
product covers or panels. Do not operate the
product without all covers and panels in place.
CONNECTION TO OTHER
INSTRUMENTS
All front panel BNC shields are connected to
the chassis ground and to the power outlet
ground via the power cord. Do not apply any
voltage to either the shields or to the outputs.
The outputs are not protected against
connection to any potential other than ground.
