Warning and cautions specific to the EX-V Series
Operating environment
For optimum performance of the EX-V, always maintain a proper operating envi-
ronment.
To prevent malfunction, do not install the EX-V in the following places:
• Places directly exposed to sunlight.
• Places where the ambient temperature drops below 0 °C or exceeds 50°C.
• Places where the relative humidity drops below 35% or exceeds 85%.
• Places where temperature fluctuations may cause condensation.
• Places where the EX-V may be exposed to corrosive or flammable gas.
• Places exposed to airborne dust or corrosive substances such as salt or
metal particles.
• Places where the EX-V may be subjected to vibration or impact.
• Places where water, oil or chemicals may splash the EX-V .
• Places where the EX-V may be affected by noise interference.
Connecting the EX-V to analog input equipment
Take the following countermeasures to prevent the EX-V from malfunctioning due
to noise interference.
Note 1: Use a 1-core shielded cable for the output line. When using an analog
voltage signal, do not use a cable longer than 10 m. If the cable needs to be
longer than 10 m, convert the voltage signal into a current signal.
Note 2: Keep the wiring and connection cables separate.
Note 3: Isolate the wiring and connection cables from high-voltage or power lines;
otherwise noise may cause the EX-V to malfunction.
