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 connecte d 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 e ssential t o connect the ea rth 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 vol tage since it has
isobaric electric potential as the ground.
Observe All Terminal Ratings.
To avoid fire or shock hazard, obse rve all ratings and ma rkers on the ins trument 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
Do Not Operate With Suspected Failures.
If yo u suspect damage occurs to the instrument, have it inspected by RIGOL
authorized personnel before further oper at io ns. 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 instrument temperature which
would cause damage to the instrument. 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 t o the interi or of the device or electric s hock, 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 persona l injuries, it is im portant to operate
the device away fr om an expl osive 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 p rotective en vironment to av oid
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.

To Connect to Power
DP800 series power supply supports various AC power supply inputs. The voltage
selector setting at the rear panel differs when the input power connected is different,
as shown in the table below.
Table 2 AC Input Power Specifications (including voltage selector settings)
Please connect the power following the steps below.
1. Check the input power
Make sure that the AC power to be connected to the instrument fulfills the
requirements in Table 2.
2. Check the voltage selector at the rear panel
Make sure that the v oltage selector setting (110, 115 or 230 ) at the rear panel of
the instrument matches the actual input voltage (for the matching relations,
refer to Table 2).
3. Check the fuse
When the instrument leav es f actory, the specified fuse is installed. Please chec k
whether the fuse matches the actual input voltage according to the “Input
Power R e quirements” at the rear panel of the instrument or Table 3.
4. Connect the AC power
Connect the instrument to AC power supply using the power cord provided in
the accessories.
To avoid electric shock, make sure that the instrument is correctly
