1Safety Requirement
1.1 General Safety Summary
Please review the following safety precautions carefully before putting the instrument
into operation so as to avoid any personal injury or damage to the instrument and
any product connected to it. To prevent potential hazards, please follow the
instructions specified in this manual to use the instrument properly.
• Use the BNC Output Connectors Properly.
The front-panel and BNC output connectors only allow signal output but unable
to support signal input.
• Use Proper Power Cord.
Only the exclusive power cord designed for the instrument and authorized for
use within the destination country could be used.
• Observe All Terminal Ratings.
To avoid fire or shock hazard, observe all ratings and markers on the instrument
and check your manual for more information about ratings before connecting
the instrument.
• Use Proper Overvoltage Protection.
Ensure that no overvoltage (such as that caused by a bolt of lightning) can reach
the product. Otherwise, the operator might be exposed to the danger of an
electric shock.
• Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
• Do Not Insert Objects into the Air Outlet.
Do not insert objects into the air outlet, as doing so may cause damage to the
instrument.
• Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the instrument is
powered on.
• Do Not Operate With Suspected Failures.
If you suspect that any damage may occur to the instrument, have it inspected
by RIGOL authorized personnel before further operations. Any maintenance,
adjustment or replacement especially to circuits or accessories must be
performed by RIGOL authorized personnel.
• Provide Adequate Ventilation.
Safety Requirement
Copyright ©RIGOL TECHNOLOGIES CO., LTD. All rights reserved. DG900 Pro User Guide
1

Inadequate ventilation may cause an increase of temperature in the instrument,
which would cause damage to the instrument. So please keep the instrument
well ventilated and inspect the air outlet and the fan regularly.
• Do Not Operate in Wet Conditions.
To avoid short circuit inside the instrument or electric shock, never operate the
instrument in a humid environment.
• Do Not Operate in an Explosive Atmosphere.
To avoid personal injuries or damage to the instrument, never operate the
instrument in an explosive atmosphere.
• Keep Instrument Surfaces Clean and Dry.
To avoid dust or moisture from affecting the performance of the instrument,
keep the surfaces of the instrument clean and dry.
• Prevent Electrostatic Impact.
Operate the instrument in an electrostatic discharge protective environment to
avoid damage induced by static discharges. Always ground both the internal and
external conductors of cables to release static before making connections.
• Use the Battery Properly.
Do not expose the battery (if available) to high temperature or fire. Keep it out of
the reach of children. Improper change of a battery (lithium battery) may cause
an explosion. Use the RIGOL specified battery only.
• Handle with Caution.
Please handle with care during transportation to avoid damage to keys, knobs,
interfaces, and other parts on the panels.
WARNING
Equipment meeting Class A requirements may not offer adequate protection to broadcast
services within residential environment.

1.3 Measurement Category
Measurement Category
This instrument can make measurements in Measurement Category I.
WARNING
This instrument can only be used for measurements within its specified measurement
categories.
Measurement Category Definitions
• Measurement category I is for measurements performed on circuits not directly
connected to MAINS. Examples are measurements on circuits not derived from
MAINS, and specially protected (internal) MAINS derived circuits. In the latter
case, transient stresses are variable. Thus, you must know the transient withstand
capability of the equipment.
• Measurement category II is for measurements performed on circuits directly
connected to low voltage installation. Examples are measurements on household
appliances, portable tools and similar equipment.
• Measurement category III is for measurements performed in the building
installation. Examples are measurements on distribution boards, circuit-breakers,
wiring (including cables, bus-bars, junction boxes, switches and socket-outlets) in
the fixed installation, and equipment for industrial use and some other
Safety Requirement

equipment. For example, stationary motors with permanent connection to a
fixed installation.
• Measurement category IV is for measurements performed at the source of a
low-voltage installation. Examples are electricity meters and measurements on
primary overcurrent protection devices and ripple control units.
1.4 Ventilation Requirement
This instrument uses a fan to force cooling. Please make sure that the air inlet and
outlet areas are free from obstructions and have free air. When using the instrument
in a bench-top or rack setting, provide at least 10 cm clearance beside, above and
behind the instrument for adequate ventilation.
CAUTION
Inadequate ventilation may cause an increase of temperature in the instrument, which
would cause damage to the instrument. So please keep the instrument well ventilated and
inspect the air outlet and the fan regularly.
1.5 Working Environment

Protection Level Against Electric Shock
ESD ±8kV
Installation (Overvoltage) Category
This product is powered by mains conforming to installation (overvoltage) category II.
WARNING
Ensure that no overvoltage (such as that caused by a bolt of lightning) can reach the
product. Otherwise, the operator might be exposed to the danger of an electric shock.
Installation (Overvoltage) Category Definitions
Installation (overvoltage) category I refers to signal level which is applicable to
equipment measurement terminals connected to the source circuit. Among these
terminals, precautions are done to limit the transient voltage to a low level.
Installation (overvoltage) category II refers to the local power distribution level which
is applicable to equipment connected to the AC line (AC power).
Pollution Degree
Pollution Degree 2
Pollution Degree Definition
• Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs.
The pollution has no effect. For example, a clean room or air-conditioned office
environment.
• Pollution Degree 2: Normally only nonconductive pollution occurs. Temporary
conductivity caused by condensation is to be expected. For example, indoor
environment.
• Pollution Degree 3: Conductive pollution or dry nonconductive pollution that
becomes conductive due to condensation occurs. For example, sheltered
outdoor environment.
• Pollution Degree 4: The pollution generates persistent conductivity caused by
conductive dust, rain, or snow. For example, outdoor areas.
