NEUMANN-Phase Rotation Indicator have been constructed and verified
in compliance with the latest safety standards for Test Instruments IEC/EN
61010-1, IEC/EN 61010-031 and IEC/EN 61557-7 and have left the factory in
safe and perfect conditions.
In order to avoid electrical shock, the valid safety and VDE regulations regard-
ing excessive contact voltages must receive utmost attention, when working
with voltages exceeding 120V (60V) DC or 50V (25V)rms AC. The values in
brackets are valid for limited ranges (as for example medicine and agricul-
ture).
Prior to usage ensure perfect instrument function.
In case of the use of measurement accessories, the measurement category is
defined by the lower value from accessories or instrument.
The safety can no longer be insured if the instrument:
• shows obvious damage
• does not carry out the desired measurements
• has been stored for too long under unfavourable conditions
• has been subjected to mechanical stress during transport.
The instrument may only be used under those conditions and for those pur-
poses for which it was conceived. For this reason, in particular the safety refer-
ences, the technical data including environmental conditions and the usage in
dry environments must be followed. When modifying or changing the instru-
ment, the operational safety is no longer ensured.
The respective accident prevention regulations established by the professional
associations for electrical systems and equipment must be strictly met at all
times.
