General Safety Considerations
The following safety notes apply specifically to HP ESG-D Series Signal Generators. These notes also
appear in other chapters of this service guide as required.
WARNING: These servicing instructions are for use by qualified personal only. To avoid electrical
shock, do not perform any servicing unless you are qualified to do so.
WARNING: The opening of covers or removal of parts is likely to expose dangerous voltages.
Disconnect the product from all voltage sources while it is being opened.
WARNING: The detachable power cord is the instrument disconnecting device. It disconnects the
mains circuits from the mains supply before other parts of the instrument. The front
panel switch is only a standby switch and is not a LINE switch.
WARNING: The power cord is connected to internal capacitors that may remain live for 5 seconds
after disconnecting the plug from its power supply.
WARNING: This is a Safety Class 1 Product (provided with a protective earthing ground
incorporated in the power cord). The mains plug shall only be inserted in a socket
outlet provided with a protective earth contact. Any interruption of the protective
conductor inside or outside of the product is likely to make the product dangerous.
Intentional interruption is prohibited.
CAUTION: Many of the assemblies in this instrument are very susceptible to damage from ESD
(electrostatic discharge). Perform service procedures only at a static-safe workstation and
wear a grounding strap.
