Getting Started
The procedure for removing shield-ground connection inside the
SR470 is as follows: First, turn o
ff
and unplug the unit. Wait one
minute after removing power to reduce the risk due to residual volt-
ages inside the instrument. To remove the top cover, first remove the
four large screws from the top cover of the instrument. The cover can
now be removed by carefully sliding it back towards the rear of the
instrument while tilting it up (from the rear). The ground connection
for the cable shield is in the form of a three-pin header, which is
located adjacent to the shutter output connector. A two-pin jumper
on the header selects whether the cable shield is in the grounded or
floating configuration, as illustrated in Fig. 1.6. Replace the cover of
the instrument and re-install the four cover screws before once again
attaching it to power.
Dangerous voltages, capable of causing injury or death, are present
WARNING
in this instrument. Use extreme caution whenever the instrument
covers are removed. Do not remove the covers while the unit is
plugged into a live outlet.
