
flammable substances, liquids, etc.) Otherwise, it can cause fire or electrical shock.
Do not place the product in an unstable location or use incomplete mountings. Otherwise, it

may cause the device to fall.
Be sure to connect the product to the stipulated power supply voltage. Connecting to a

different voltage might cause a fire or electrical shock.
If the product is used in a manner not specified by the manufacturer, the protection provided

by the equipment may be impaired.
The product is not intended for use in aerospace, space, nuclear power, medical equipment, or



disaster prevention or security systems, please contact your retailer.
Be certain the following requirements are satisfied when using the product.

- Indoor use
- Altitude up to 5000m
- Applicable POLLUTION DEGREE 2
When using the product at high altitudes, refer to the relational expression below to find an
appropriate ambient temperature. The heat dissipation decreases due to air pressure drop and
could lead to damages or a shorter product life.
- Ambient temperature = 60[°C] - 0.005 x altitude [m]
An Example)
The product is used at 3000 meters
60°C - (0.005 x 3000m) = 45°C (Ambient temperature)
Do not use or store the product in a location exposed to extremely high or low temperature

that exceeds range of specification or susceptible to rapid temperature changes.
e.g. - Exposure to direct sun
- In the vicinity of a heat source
Do not use the product in extremely humid or dusty locations. It is extremely dangerous to use

the product with its interior penetrated by water or any other fluid or conductive dust. If the
product must be used in such an environment, install it on a dust-proof control panel, for
example.
