1. 1. 1. 1. SAFETY SAFETY SAFETY SAFETY
Before using the Power Analyzer, read the following safety information carefully. In this
manual „WARNING“
„WARNING“ „WARNING“ „WARNING“ is reserved for conditions that pose hazards to the user;
„CAUTION“
„CAUTION“ „CAUTION“
„CAUTION“ is reserved for conditions that may damage your instrument.
„ Avoid working alone.
„ Follow all safety procedures for equipment being tested.
„ Inspect the test leads for damaged insulation.
„ Be sure the Power Analyzer is in good operating condition.
„ To avoid electrical shock, use caution when working above 30V dc or rms.
„ Disconnect the live test leads before disconnecting the common test leads.
„ When making a current- or power measurement, turn the circuit power off before
connecting the Power Analyzer in the circuit.
„ Switching on inductive loads means large inrush currents. Take precautions to
avoid overloading the current channels by shorting the start-up currents across
the current inputs.
„ Switching off inductive loads or switching on rotating loads means large voltages
or extremely fast changing voltages on the Power Analyzer input terminals. Such
conditions may damage the instrument and are potentially hazardous.
„ To comply with EN50081-1 the current- and voltage test leads must form 6
windings through ferrite torroid Siemens B64290-L40-X830 or equivalent. (This
measure will also enhance immunity with respect to fast common mode
transients), the RS-232 interface cable must be shielded and must form 1
winding through Fair-rite VO
0
444176451.
„ 1kV burst test: use shielded input- and output cables.
„ The Power Analyzer complies with the safety standards IEC 1010-1,
EN 61010-1.
1.1 1.1 1.1 1.1 WARNINGS WARNINGS WARNINGS WARNINGS
„ Before reading the manual or before using this instrument read carefully the
warnings below and make sure you understand them.
„ WARNING: Line Power
WARNING: Line Power WARNING: Line Power
WARNING: Line Power
To avoid shock hazard, connect the instrument power cord to a power receptacle
with earth ground.
„ WARNING WARNING WARNING WARNING
The maximum floating voltage above earth ground on the current input terminals
and the voltage Lo-input terminals is 600V. Exceeding these limits poses a
hazard to the meter and operator.
„ WARNING WARNING WARNING WARNING
Qualified personnel must operate this instrument.
„ WARNING WARNING WARNING WARNING
Refer all servicing of this instrument to qualified personnel. Before opening case
disconnect all leads connected to the instrument and finally disconnect the power
line cord.
„ WARNING WARNING WARNING WARNING
The specifications given in this manual solely describe the technical properties of
the instrument. They do not imply any other properties unless it is explicitly said
so.
„ WARNING WARNING WARNING WARNING
Use of this instrument in life support systems and in systems for people
transportation must be expressly authorized.
The manufacturer of this Power Analyzer must sign the authorization.
„ WARNING WARNING WARNING WARNING
Do not operate the front panel keys with pointed objects. A damaged key may
pose shock hazard.
If you observe a damaged front panel key, please report this to your nearest
Infratek representative and return the instrument for repair.
