Replacing Assemblies
Replacing Assemblies
This chapter tells you what to do before and after you replace an
assembly and shows you how to disassemble the analyzer.
WARNING:
Disconnect the power cord from the rear panel before
disassembly or assembly of the Agilent 89410A.
Even with power removed, there can be sufficient stored energy in some circuits to
cause personal injury. These voltages will discharge to a relatively safe level
approximately five minutes after the power cord is disconnected.
CAUTION:
Do not connect or disconnect cables from circuit assemblies with the
line power turned on ( l ).
To protect circuits from static discharge, remove or replace assemblies only at
static-protected work stations.
