Prodigit 3270 Series Operation Manual page 3

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.
