Electrostatic Discharge (ESD) Precautions
Almost all electrical components can be damaged by electrostatic discharge (ESD)
during handling. Component damage can occur at electrostatic discharge voltages as
low as 50 volts.
The following guidelines will help prevent ESD damage when serving the power
supply or any electronic device.
• Disassemble instruments only in a static-free work area.
• Use a conductive work area to dissipate static charge.
• Use a conductive wrist strap to dissipate static charge accumulation.
• Minimize handling.
• Keep replacement parts in original static-free packaging.
• Remove all plastic, styrofoam, vinyl, paper, and other static-generating materials
from the immediate work area.
• Use only anti-static solder suckers.
Surface Mount Repair
Surface mount components should only be removed using soldering irons or
disordering stations expressly designed for surface mount components.
Use of conventional solder removal equipment will almost always result in permanent
damage to the printed circuit board and will void your Agilent Technologies factory
warranty.
To Replace the Power-Line Fuse
The power-line fuse is located within the power supply’s fuse-holder assembly on the
rear panel (see page 22). See page 22 to check the rating of power-line fuse and replace
with the correct one for your power supply.
