SAFETY PRECAUTIONS
The following warnings, which appear both here and in the main body of the test, are to alert the user of
potential safety hazards and to encourage safe operating practices.
WARNING: To avoid possible electric shock, observe the following:
Do not operate with the cover removed. Exposed ac power is present even with the power switch off.
Be sure the ground conductor of the ac power cord connects the instrument to a solid earth ground.
WARNING: To remove all ac power from the unit, the line cord must be unplugged.
WARNING: To avoid accidental shock, unplug the line cord and turn the power off before checking or
replacing the fuse. For protection against fire, use only the specified fuse value. Do not attempt to
bypass or repair the fuse.
The following cautions, which appear both here and in the main body of the text, are to prevent
equipment damage that could result from improper operation.
CAUTION: The module must be installed with mainframe power off. A module can be damaged or
have its memory corrupted if inserted or removed from the mainframe with the power on.
CAUTION: Before plugging the instrument into a 234 V ac line, be sure the 115 V/230 V selection
switch is set to 230 V and a fuse of proper value is in place. Do not move this switch while the power is
on.
