MOUNTING
This chapter describes installation environment, mounting cautions, dimensions and mounting
procedures.
3.1 Mounting Cautions
(1) This instrument is intended to be used under the following environmental conditions.
(IEC61010-1)
[OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2]
(2) Use this instrument within the following environment conditions.
•
Allowable ambient temperature:
−
10 to
+
50
°
C
•
Allowable ambient humidity:
5 to 95 % RH
(Absolute humidity: MAX.W.C
29.3 g/m
3
dry air at 101.3 kPa)
•
Installation environment conditions: Indoor use
Altitude up to 2000 m
(3) Avoid the following conditions when selecting the mounting location.
•
Rapid changes in ambient temperature which may cause condensation.
•
Corrosive or inflammable gases.
•
Direct vibration or shock to the mainframe.
•
Water, oil, chemicals, vapor or steam splashes.
•
Excessive dust, salt or iron particles.
•
Excessive induction noise, static electricity, magnetic fields or noise.
•
Direct air flow from an air conditioner.
•
Exposure to direct sunlight.
•
Excessive heat accumulation.
(4) Take the following points into consideration when mounting this instrument.
•
Ensure at least 50 mm space on top and bottom of the instrument for maintenance and
environmental reasons.
•
Do not mount this instrument directly above equipment that generates large amount of heat
(heaters, transformers, semi-conductor functional devices, large-wattage resistors).
•
If the ambient temperature rises above 50
°
C, cool this instrument with a forced air fan, cooler,
or the like. However, do not allow cooled air to blow this instrument directly.
•
In order to improve safety and the immunity to withstand noise, mount this instrument as far
away as possible from high voltage equipment, power lines, and rotating machinery.
High voltage equipment: Do not mount within the same panel.
Power lines:
Separate at least 200 mm.
Rotating machinery:
Separate as far as possible.
To prevent electric shock or instrument failure, always turn off the power before
mounting or removing the instrument.
