How To Mount - SMC Networks IZN10 Series Operation Manual

4. Environment to avoid
Do not use or store under the following environments, as these may cause operation failure. If it is
unavoidable, take the appropriate measures.
a. Where ambient temperature exceeds 0 to 50
b. Where ambient humidity exceeds 35 to 65% RH.
c. Where dew condensation is generated due to sudden temperature change.
d. Where there is corrosive gas, inflammable gas, or where volatile inflammable substances are stored.
e. Where the product is exposed to conductive powder such as iron powder and dust, oil mist, salt and
organic solvent or machining chips, particles and cutting oil (water, liquid).
f. Where the product is directly exposed to the blow from air-conditioners.
g. Where seals and ventilation is not installed.
h. Where the product is exposed to direct sunlight and radiant heat.
i. Where strong electromagnetic noise is generated. (Strong electric field/strong magnetic field/surge.)
j. Where electricity is discharged on the product.
k. Where a strong high frequency is generated.
l. Where lightning disaster is expected.
m. Where the product is directly exposed to vibration and impact.
n. Where force or weight that causes deformity to the product is applied.
5. Do not use air containing mist or dust.
Air containing mist or dust may lower the function and shorten the maintenance cycle. A dryer (IDF series),
air filter (AF/AFF series) and mist separator (AFM/AM series) can be used to produce clean compressed
air.
6. The product does not incorporate a protection to lightning surges.
7. The product can not be used without air purge.
Without air purge, not only is the charge elimination not available, but also internal ozone concentration
will increase and adversely affect the product and peripheral equipment. Therefore, be sure to perform air
purge when energizing the product.

4-2.How to mount

Investigate the area generating static electricity, or the process or part emitting electrostatic interference
preliminarily, and check the conditions under which effective charge elimination can be performed before
mounting the product.
4-2-1 Grounding
Provide class D grounding to the external face of the body or metal part of the bracket. Without grounding,
charge elimination capability decreases, the ion balance breaks and electric shock and damage to the
product and power supply may occur. Also, if the grounding is provided improperly, a maintenance alarm
is outputted.
If the mounting area for the product is not provided with class D grounding, use a grounding tap for wiring.
