3. 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) Mount this instrument in the panel considering the following conditions:
• 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, etc.
Cooled air should not blow directly on this instrument.
• 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.
(5) If this instrument is permanently connected to equipment, it is important to include a switch or
circuit-breaker into the installation. This should be in close proximity to the equipment and within
easy reach of the operator. It should be marked as the disconnecting device for the equipment.
To prevent electric shock or instrument failure, always turn off the power before
mounting or removing the instrument.
