SAFETY INSTRUCTIONS
This chapter contains important safety instructions
that should be followed when operating and
storing the function generator. Read the following
before any operation to ensure your safety and to
keep the function generator in the best condition.
Safety Symbols
These safety symbols may appear in this manual or on the
instrument.
WARNING
Warning: Identifies conditions or practices that
could result in injury or loss of life.
CAUTION
Caution: Identifies conditions or practices that
could result in damage to the function generator or
to other objects or property.
DANGER High Voltage
Attention: Refer to the Manual
Signal ground. Chassis ground
Signal ground. Isolated from other channels and
ground.

SAFETY INSTRUCTIONS
5
Do not dispose electronic equipment as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased.
Safety Guidelines
General
Guideline
CAUTION
 Do not place heavy objects on the instrument.
 Do not place flammable objects on the
instrument.
 Avoid severe impact or rough handling that
may damage the function generator.
 Avoid discharges of static electricity on or near
the function generator.
 Use only mating connectors, not bare wires, for
the terminals.
 The instrument should only be disassembled by
a qualified technician.
 Do not apply more than 42Vpk to any
input/output ground or to the chassis ground.
 Do not apply voltage to the output terminals to
avoid damage to the instrument.
 Do not apply more than ±5V to the trigger or
MOD input terminals to avoid damage to the
instrument.
(Measurement categories) EN 61010-1:2010 specifies the
measurement categories and their requirements as follows. The
AFG-30XX falls under category II.
 Measurement category IV is for measurement performed at the
source of a low-voltage installation.
 Measurement category III is for measurement performed in a
building installation.
 Measurement category II is for measurement performed on
circuits directly connected to a low voltage installation.
 Measurement category I is for measurements performed on
circuits not directly connected to Mains.

Power Supply
WARNING
 AC Input voltage: 100 - 240V AC, 50 - 60Hz.
 Connect the protective grounding conductor of
the AC power cord to an earth ground to
prevent electric shock.
Fuse
WARNING
 Fuse type:
AFG-3032&3022: T1A/250V
AFG-3021&3031: T0.63A/250V
 Only qualified technicians should replace the
fuse.
 To ensure fire protection, replace the fuse only
with the specified type and rating.
 Disconnect the power cord and all test leads
before replacing the fuse.
 Make sure the cause of the fuse blowout is fixed
before replacing the fuse.
Ground
CAUTION
 The AFG-30XX is a floating function generator;
the AFG-30XXs’ common ground is electrically
isolated from the chassis ground by a 42Vpk
isolation voltage (DC + peak AC). Exceeding
42Vpp may cause damage to the internal
circuits.
 Do not short the chassis ground with
CH1(MAIN)’s or CH2’s common ground if
there is a potential voltage difference between
them. Doing so may damage the unit or
externally connected equipment.
 If there is a potential voltage between CH1’s and
CH2’s common ground, do not short them.
Doing so may damage the unit or externally
connected equipment.
WARNING
 To avoid electric shock ensure that the output
voltage and floating voltage does not exceed
42Vpk in total.
 Do not touch any exposed connectors when the
unit is being operated.

SAFETY INSTRUCTIONS
7
Cleaning the
function
generator
 Disconnect the power cord before cleaning the
function generator.
 Use a soft cloth dampened in a solution of mild
detergent and water. Do not spray any liquid
into the function generator.
 Do not use chemicals containing harsh products
such as benzene, toluene, xylene, and acetone.
Operation
Environment
 Location: Indoor, no direct sunlight, dust free,
almost non-conductive pollution (Note below)
and avoid strong magnetic fields.
 Relative Humidity: < 80%
 Altitude: < 2000m
 Temperature: 0°C to 40°C
(Pollution Degree) EN 61010-1:2010 specifies pollution degrees and
their requirements as follows. The function generator falls under
degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or
gaseous (ionized gases), that may produce a reduction of dielectric
strength or surface resistivity”.
 Pollution degree 1: No pollution or only dry, non-conductive
pollution occurs. The pollution has no influence.
 Pollution degree 2: Normally only non-conductive pollution
occurs. Occasionally, however, a temporary conductivity caused
by condensation must be expected.
 Pollution degree 3: Conductive pollution occurs, or dry, non-
conductive pollution occurs which becomes conductive due to
condensation which is expected. In such conditions, equipment
is normally protected against exposure to direct sunlight,
precipitation, and full wind pressure, but neither temperature
nor humidity is controlled.
Storage
environment
 Location: Indoor
 Relative Humidity: < 70%
 Temperature: -10°C to 70°C

Disposal
Do not dispose this instrument as unsorted
municipal waste. Please use a separate collection
facility or contact the supplier from which this
instrument was purchased. Please make sure
discarded electrical waste is properly recycled to
reduce environmental impact.
Class A Device
WARNING
The AFG-30XX function generators are categorized
as Class A equipment. Class A equipment is
intended for use in an industrial environment.
Class A equipment may have potential difficulties
in ensuring electromagnetic compatibility in other
environments, due to conducted as well as
radiated disturbances.

SAFETY INSTRUCTIONS

Power cord for the United Kingdom
When using the function generator in the United Kingdom, make sure the
power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the
following code:
Green/ Yellow:
Earth
Blue:
Neutral
Brown:
Live (Phase)
As the colours of the wires in main leads may not correspond with the
coloured marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth
terminal marked with either the letter E, the earth symbol or coloured
Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is
marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal
marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact
the supplier.
This cable/appliance should be protected by a suitably rated and approved
HBC mains fuse: refer to the rating information on the equipment and/or
user instructions for details. As a guide, a cable of 0.75mm2should be
protected by a 3A or 5A fuse. Larger conductors would normally require
13A types, depending on the connection method used.
Any exposed wiring from a cable, plug or connection that is engaged in a
live socket is extremely hazardous. If a cable or plug is deemed hazardous,
turn off the mains power and remove the cable, any fuses and fuse
assemblies. All hazardous wiring must be immediately destroyed and
replaced in accordance to the above standard.
