Disassembly 5-9
Instrument reassembly
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. To ensure
proper operation, replace and securely fasten the shield.
WARNING To ensure continued protection against electrical shock, verify that power
line ground (green and yellow wire attached to the power module) and the
power transformer ground (black wire) are connected to the chassis. When
installing the power transformer, be sure to re-connect the black ground
wire to the mounting stud on bottom of the chassis. Be sure to install the
bottom case screws to assure a good case-to-chassis ground connection.
