Reassemble the instrument by reversing the previous disassembly procedures. Make sure that
all parts are properly seated and secured, and that all connections are properly made.
WARNING
To ensure continued protection against electrical shock, verify that power
line ground (green and yellow wire attached to the power module) the
power transformer ground (black wire), and input jack ground (green wire)
are securely connected to the chassis. Also make sure that the case
grounding screws at the bottom rear are securely installed.
Power module connections
During reassembly, connect power module wires as summarized in Table 5-2 .
Board installation
During reassembly, replace the motherboard, and start the IEEE-488, RS-232, and BNC jack
connector nuts and the mounting screw. Tighten all the fasteners once they are all in place, and
the board is correctly aligned.
