Safety Requirement
General Safety Summary
Please review the following safety pre cautio ns ca refully before putting the
instrument into operation so as to avoid any personal injury or damag e t o t he
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 through the Protective Earth lead of the power cord. To
avoid ele ctric 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, 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 r atings an d markers 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 Insert Anything Into the Air Outlet.
Do not insert anything into the air outlet to avoid damage to the instrument.
Use Proper Fuse.
Please use the specified fuses.
Avoid Circuit or Wire Exposure.
Do not touch exposed j unctions and components when the unit is powered on.
II DP800A User’s Guide
RIGOL
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. An y maintenance,
adjustment or replacement especially to circuits or accessories must be perfor med by
RIGOL authorized personnel.
Provide Adequate Ventilation.
Inadequate ventilation may cause an increase of t emperatur e 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 t he
instrument in an explo sive atmosphere.
Keep Instrument Surfaces Clean and Dry.
T o a void dust or moisture from af fecting the pe rformance of the inst rument, keep the
surfaces of the instrument clean and dry.
Prevent Electrostatic Impact.
Operate the instrume nt i n an electrost atic discharge protective environ ment to a void
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 t o keys, knobs,
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.
