SAFETY GUIDE
This manual contains the precautions necessary to ensure your personal safety as well
as for protection for the products and the connected equipment. These precautions are
highlighted with a triangle “WARNING” symbol in this manual and are marked according to
the danger levels as follows:
Danger
It indicates that if appropriate precautions are not taken, serious incidents of personal
injuries and deaths or significant damages or losses to the properties will be caused.
Caution
It indicates that if appropriate precautions are not taken,injuries or losses of properties
will take place
Note:
Reminds you to pay particular attention to the important information related to the
products, disposal of products or the specific part of documents.
Warning
Only qualified personnel are allowed to debug and operate this equipment. The qualified
personnel are specified as those personnel who carry out commissioning, grounding and
apply the volume identification to the circuits, equipment and systems according to the
available safety practices and standards.
Note
Only when this product is transported, stored assembled and installed in a proper way
and operated and maintained according to the recommendations, can it implement the func-
tions properly and reliably.

3600 SERIES USER MANUAL
The following general safety precautions must be observed during all phases of
operation, service, and repair of this instrument. Failure to comply with these precau-
tions or with specific warnings elsewhere in this manual violates safety standards of
design, manufacture, and intended use of the instrument. The Manufacturer assumes
no liability for the customer’s failure to comply with these requirements.
I.Safety
1. Users should operate according to this manual.
2. There is high voltage inside the instrument, please avoid touching it directly.
3. Please read the user manual carefully before you use the instrument to assure your
safety.
4. Ground the Instrument
This product is provided with a protective earth terminal. To minisize shock hazard,
the instrument chassis and cabinet must be connected to an electrical ground. The
instrument must be connected to the AC power supply mains through a three-conduc-
tor power cable, with the third wire firmly connected to an electrical ground (safety
ground) at the power outlet.
5.KeepAway From Live Circuits
Operating personnel must not remove instrument covers. Component replacement
and internal adjustments must be made by qualified service personnel. Do not split the
components when power cable connected.
Under certain conditions, dangerous voltages may exist even with the power cable
removed. To avoid injuries, always disconnect power, discharge circuits and remove
external voltage sources before touching components.
Do Not Substitute Parts or Modify Instrument
Because of the danger of introducing additional hazards, do not install substitute
parts or perform any unauthorized modification to the instrument. Return the instrument
to a qualified dealer for service and repair to ensure that safety features are maintained.
II.Connecting thepowerline
1. Inspect the power selection switch on the back panel, to assure if the selected
voltage is the same as environment power voltage. If not, please refer to the notice
around the power plug.
2. Before connecting the power supply, please be sure that the switch on the front
panel should be in the off position.

3. Connect the power cable to the AC in the power supply and the 3 connector plug.
Please be sure that the power supply is grounded.
4. Press the switch on the front panel to switch on the instrument and you can start
to use it.
III.Fuse
1. The fuse is at the position of power input part on the back panel, for the purpose
of avoiding failure brought by using wrong voltage. Please pay attention to the follow-
ing items when you change the voltage input and the fuse.
2. Before changing the voltage and fuse, please be sure that theAC power is switch-
ing off, and be sure that there is no other equipment connected to this instrument.
3. Put a screwdriver into the fuse mounting, press it and the fuse mounting will pop up.
4. Pull out the fuse, change it according to the label beside the power input plug.
Warning: To avoid damaging the instrument, please be sure to change a suitable
typefuse.
IV.Powersupply
1. For safety reasons, please be sure not to have any short circuit between plus and
minus pole.
2. Output wire should be insulated completely to the connected equipment.
3. Before using the instrument, you should switch on the power supply for 30 minutes.
