SAFETY SUMMARY
The following general safety precautions must be observed during all phases of operation, service,
and repair of this instrument. Failure to comply with these precautions or with specific warnings
elsewhere in this manual violates safety standards of design, manufacture, and intended use of the
instrument. PRODIGIT assumes no liability for the customer's failure to comply with these
requirements.
GENERAL
This product is a Safety Class 1 instrument (provided with a protective earth terminal). The protective
features of this product may be impaired if it is used in a manner not specified in the operation
instructions.
ENVIRONMENTAL CONDITIONS
This instrument is intended for indoor use in an installation category I, pollution degree 2 environments.
It is designed to operate at a maximum relative humidity of 80% and at altitudes of up to 2000 meters.
Refer to the specifications tables for the ac mains voltage requirements and ambient operating
temperature range.
BEFORE APPLYING POWER
Verify that the product is set to match the available line voltage and the correct fuse is installed.
GROUND THE INSTRUMENT
This product is a Safety Class 1 instrument (provided with a protective earth terminal). To minimize
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 conductor
power cable, with the third wire firmly connected to an electrical ground (safety ground) at the power
outlet. Any interruption of the protective (grounding) conductor or disconnection of the protective earth
terminal will cause a potential shock hazard that could result in personal injury.
FUSES
Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.)
should be used. Do not use repaired
Fuses or short circuited fuse holder. To do so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and internal
adjustments must be made by qualified service personnel. Do not replace components with 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 SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another person, capable of rendering first aid and
resuscitation, is present.
DO NOT EXCEED INPUT RATINGS.
This instrument may be equipped with a line filter to reduce electromagnetic interference and must be
connected to a properly grounded receptacle to minimize electric shock hazard. Operation at line
voltages or frequencies in excess of those stated on the data plate may cause leakage currents in
excess of 5.0 mA peak.
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 PRODIGIT ELECTRONICS
Sales and Service Office for service and repair to ensure that safety features
are maintained.
Instruments which appear damaged or defective should be made inoperative and secured against
unintended operation until they can be repaired by qualified service personnel.

4016 Series Operation Manual 5
Chapter 2 Installation
2-1 Inspection
The 4016 Series AC/DC Digital Power Analyzer was carefully inspected before shipment. If
instrument damage has occurred during transport, please inform Prodigit's sales and service
office or representative.
You’re 4016 Series AC/DC Digital Power Analyzer was shipped with a power cord for the type
of Terminal blocks used at your location. If the appropriated cord was not included, please
contact your nearest Prodigit sales office to obtain the correct cord. Refer to “check line
voltage “to check the line voltage is 100V~230Vac.
2-2 Check line voltage
The 4016 Series AC/DC Digital Power Analyzer can operation with 100 Vac ~230Vac input as
indicated on the label on the rear panel.
Make sure that the factory check mark corresponds to your nominal line voltage. Skip this
procedure if the label is corrected marked.
2.2.1. With the 4016 Series AC/DC Digital Power Analyzer power OFF, disconnect the
Power cord.
2.2.2. Refer the drawing on the rear panel of 4016 Series high power Digital Power
Analyzer in Fig 2-1.
Fig 2-1 4016 Series AC Input Connection
2-3 Fuse Exchange
This product has the power fuse, and exchanges it according to the following procedure.
Never fail to turn off the power of this product, and disconnect the plug of the AC Power
cable.

6PRODIGIT
2.3.1.Check the rating of the line fuse and replace it with the correct fuse if necessary.
100V~230V use T0.5A/250V (5*20mm).
2.3.2.The AC line fuse is located below the AC line receptacle see Fig 2-2. Use a small
Screwdriver to extract the fuse holder, to change a new one. Change an appropriate
Specifications fuse which indicated in Table 1-1.
2.3.3.Reinstall fuse holder and connect the power cord.
Fig 2-2 4016Series fuse holder
2-4 Grounding requirements
SHOCK HAZARD
1. It is requested to use the 3Pin plug connector only for 4016 Series mainframe to out of
danger when electric leakage. And the complete and proper grounded is necessary.
2. The 4016 Series high power AC/DC Digital Power Analyzer is equipped with three
conductor cable which plugs in an appropriate receptacle to ground the instrument's
cover.
To avoid the fire or electronic shock, the Fuse that will be used in the product should have
the safety standard in the area of the region you use. Any use of improper Fuse or shorting
the Fuse holder would be extremely dangerous and would be strictly prohibited.
・Before exchanging the Fuse, if there are abnormal odor or abnormal noise,
・Please stop using immediately and ask for the repair.
