Safety Precautions
Before use, read these instructions carefully to properly operate the instrument.
Be sure to follow the precautions described here for personnel and product safety.
Keep this manual ready to hand and accessible for future use at all times.
Be sure to forward the manual to the end user.
If you consider using the instrument for a special purpose such as nuclear power plants, aerospace, medical
care, or passenger vehicles, consult with our sales representative.
The instructional icon in the manual is described as follows.
The caution icon ( ) on the main unit indicates that incorrect handling may cause
hazardous conditions. Always follow the subsequent instructions (
) because
they are important to personal safety.
Failure to follow them may result in an
electric shock, a fire, erroneous operation, or damage to the instrument. If the
instrument is used in a manner not specified by the manufacturer, the protection
provided by the instrument may be impaired.
CAUTION
The terminals of auxiliary power (MA, MB) and voltage input (P1, P2, P3, PN) have
hazards of electric shock, explosion, or arc flash. Turn off the power supply of auxiliary
power and input circuit and then handle the instrument.

Precautions on use environment and conditions
Do not use the instrument in the following circumstances:
Failure to follow the instruction may cause a malfunction or
r
educed product life time.
The ambient temperature exceeds the range -5°C to +55°C.
The average daily temperature e35°C.
The relative humidity exceeds the range 0 to 85% RH, or condensing.
The altitude exceeds 2000 m.
Pollution Degree: more than 2 *Note 1
Exposed to much dust, corrosive gas, salty environment, or oil mist
Transient over voltage: 4000 V *Note 1
Exposed to excessive vibration or impact
Exposed to rain or water drops
Exposed to direct sunlight
Pieces of metal or inductive substances are scattered.
Exposed to strong magnetic fields or large exogenous noise
*Note1: For details about the

refer to EN61010-1:2010.
Grit, dust, and small insects cause poor contact or a failure such as insulation decline that caused by
deposition and moisture absorption. Furthermore, in the area where the air contains conductive dust, a
failure such as a product malfunction or insulation deterioration occurs in a relatively short time. In this
case, you must take measures against it such as putting the instrument in an enclosed board. In
addition, if the temperature inside the board rises, the measures must be undertaken as well.
