Chapter 4 Assembly Procedures
This chapter describes how to remove the major modules from the SDG2000X
series generator. To install the removed modules or replace new modules,
please follow corresponding operating steps in reverse order.
The following subjects are addressed in this chapter:
Security Consideration which describes security information needed to
considerate while operating.
List of Module in which the modules to remove are listed.
Required Tool which describes the tools needed to perform the
procedures
Disassembly Procedures which describes in detail how to remove and
install the modules
Security Consideration
Only qualified personnel should perform the disassembly procedures.
Whenever possible, disconnect the power before removing or replacing.
Otherwise, personal injuries or damages to the components may occur.
Avoid Electric Shock Hazardous voltages exist on the LCD module and
power supply module. To avoid electrical shock, disconnect the power cord
from the generator, and then wait at least three minutes for the capacitors in
the generator to discharge before beginning the disassembly.
Preventing ESD Almost all electrical components can be damaged by
electrostatic discharge (ESD) during handling. Component damages can occur
at electrostatic discharge voltages as low as 50 volts. The following guidelines
will help preventing ESD damage when servicing the instrument or any
electronic device.
Disassemble instruments only in a static-free work area.
Use a conductive work area to reduce static charges.
Use a conductive wrist strap to reduce static charge accumulation.
Minimize handling.
Keep replacement parts in original static-free packaging.
