Chapter 2 Preparing for Installation
2.1 Site Requirements
The F100-C-EI must be used indoors. To ensure its proper
operation and extend its longevity, install it in an environment that
meets the requirements described in the following subsections.
2.1.1 Temperature and Humidity Requirements
The equipment room must maintain adequate temperature and
humidity.
z
Long-lasting high humidity is prone to cause bad insulation
and even electricity creepage. Sometimes the mechanical
performance changes of materials, the rustiness and
corrosion of some metal parts are also likely to occur.
z
If the relative humidity is too low, the captive screws can
become loose due to insulation washer contraction.
Meanwhile, the static is likely produced in the dry
environments, jeopardizing the CMOS circuits of the
product.
z
The higher the temperature is, the greater the damage to
your device. Long-lasting high temperature can speed up
the aging of the insulation materials, greatly lower the device
reliability, and hence significantly shorten its service life.
The following table lists the temperature and humidity
requirements.
