3.2 Installation Environment

The programmable controller and I/O modules mounted in it must be used within the installation
environment specified in Table 3-1. To ensure a long-term stable performance of these
hardware products, the user is recommended to use them at normal temperature and normal
humidity (15 to 35°C, 45 to 85%RH). If they are used in a high-temperature and high-humidity
environment or an environment where the temperature fluctuates widely between day and night,
their useful service life will be shortened.

It may happen that the input voltage of the power supply module is within the
above specifications but it is close to the upper or lower limit. In these cases,
the user is advised to consider the input voltage as being abnormal and ask a
power supply management specialist for inspection of the module.
