General Safety Considerations
The following safety notes apply specifically to ESG Family 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 (disconnecting device).
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.
WARNING Danger of explosion if battery if incorrectly replaced. Replace only
with the same or equivalent type recommended. Discard used
batteries according to manufacturer’s instructions.
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.
