Safety Requirement
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 Proper Power Cord.
Only the exclusive power cord designed for the instrument and authorized for use
within the local country could be used.
Ground the Instrument.
The instrument is grounded th rou gh t he Protective Earth lead of the p ower cord. To
avoid electric shock, connect the earth terminal of the power cord to the Protective
Earth terminal before connecting any input or output terminals.
Connect the Probe Correctly.
If a probe is used, the probe ground lead must be connected to earth ground. Do not
connect the ground lead to high voltage. Improper w ay of connection could res ult in
dangerous voltages being present on the connectors, controls or other surfaces of
the oscilloscope and probes, which will cause potential hazards for operators.
Observe All Terminal Ratings.
To avoid fire or shock hazard, observ e all rat ings and ma rkers on the instrume nt and
check your manual for more information about ratings before connecting the
instrument.
Use Proper Overvoltage Protection.
Ensure that no over voltage (su ch as that cause d by a bolt of lightni ng) 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 Inser t O bj e cts Into the Air Outlet.
Do not insert objects into the air outlet, as doing so may cause damage to the
instrument.
Use Proper Fuse.
Please use the specified fuses.
II DL3000 User’s Guide
RIGOL
Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the unit 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.
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 Product Surfaces Clean and Dry.
T o a void dust or moisture from af fecting the pe rformance of the inst rument, keep th e
surfaces of the instrument clean and dry.
Prevent Ele c tr o static Imp act.
Operate the instrume nt i n an el ectr ostatic dischar ge protectiv e e nvi ron ment to a void
damage induced by static discharges. Always ground both the internal and external
conductors of cables to releas e sta t i c be fore 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.

To Connect to Power Supply
Two kinds of AC power inputs are supported by the DL3000 series. When it is
connected to different power sources, the AC selector setting on its rear panel is
different, as shown in Table 1-1.
Table 1-1 AC Input Power Specification and AC Selector Setting
Please strictly follow the steps below to connect the DL3000 electronic load to the
power supply.
1． Check the input power
Ensure that the AC power to be connected t o t he load conforms to the AC input
power requirement specified in Table 1-1.
2． Check the AC selector
Ensure that the AC selector setting (115 V or 230 V) on the rear panel of the load
matches the actual AC input power (For the match relationship, refer to Table
1-1).
3． Check the fuse
When leaving the factory, the load has installed a fuse that conforms to the
destination country standard. Please ref er to the "fuse rating" on the rear panel
of the load or refer to Table 1-2 to ensure that the fuse matches the actual AC
input power.
4． Connect the AC power
Plug the specified power cord available in the accessories into the AC power
supply connector of the instrument, and then connect the instrument to the
properly grounded AC power.
To avoid electric shock, ensure that the instrument is correctly
