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 V.
The following guidelines will help prevent ESD damage when servicing 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
material 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 Keysight factory
warranty.
Replacing the Power-Line Fuse
The power-line fuse is located within the fuse-holder assembly on the rear panel
of the power supply. Refer to “Connecting power to the power supply” on page 31
to check the rating of the power-line fuse and replace with the correct one for
your power supply.
