Precaution when used at an operating ambient temperature below 0
• With some exceptions, the operating ambient temperature is -20 to 55
for the FX5 PLCs manufactured in June 2016
onwards.
• The operating ambient temperature is 0 to 55
for the FX5 PLCs manufactured before June 2016.
• When the device is used in a low-temperature environment, use care not to let the product freeze or condensation to occur.
• When used in a low-temperature environment, use in an environment with no sudden temperature changes. If there are
sudden temperature changes because of opening/closing of the control panel or other reasons, condensation may occur,
which may cause a fire, fault, or malfunction. Furthermore, use an air conditioner in dehumidifier mode to prevent
condensation.
