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 use
the instrument only specified by this manual.
Use Proper Power Cord.
Only the power cord designed for the instrument and authorized for use within the
local country could be used.
Ground the Instrument.
The instrument is grounded through the Protective Earth lead of the power cord. To
avoid electric shock, it is essential to connect the earth terminal of the power cord to
the Protective Earth terminal before connecting any inputs or outputs.
Connect the Probe Correctly.
If a probe is used, do not connect the ground lead to high voltage since it has
isobaric electric potential as the ground.
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.
Make sure that no overvoltage (such as that caused by a thunderstorm) can reach
the product, or else the operator might be exposed to the danger of electrical shock.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Do Not Insert Anything Into the Holes of Fan.
Do not insert anything into the holes of the fan to avoid damaging the instrument.
Use Proper Fuse.
Please use the specified fuses.
Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the unit is powered.

RIGOL
DP800A User’s Guide III
Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected by qualified
service personnel before further operations. Any maintenance, adjustment or
replacement especially to circuits or accessories must be performed by RIGOL
authorized personnel.
Keep Well Ventilation.
Inadequate ventilation may cause an increase of temperature or damage to the
device. So please keep the instrument well ventilated and inspect the intake and fan
regularly.
Do Not Operate in Wet Conditions.
In order to avoid short circuiting to the interior of the device or electric shock, please
do not operate the instrument in a humid environment.
Do Not Operate in an Explosive Atmosphere.
In order to avoid damage to the device or personal injuries, it is important to operate
the device away from an explosive atmosphere.
Keep Product Surfaces Clean and Dry.
To avoid the influence of dust and/or moisture in the air, please keep the surface of
the device clean and dry.
Electrostatic Prevention.
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.
Proper Use of Battery.
If a battery is supplied, it must not be exposed to high temperature or in contact with
fire. Keep it out of the reach of children. Improper change of battery (note: lithium
battery) may cause explosion. Use RIGOL specified battery only.
Handling Safety.
Please handle with care during transportation to avoid damage to buttons, knob
interfaces and other parts on the panels.
Do Not Provide Power for the Active Load.
In order to avoid the anti-irrigation current which leads to the power control loop out
of control and damages the powered device, this power supply can only provide
power for the pure load without the current output function.
