2. Handling Cautions
This chapter provides important information on how
to handle the indicator. Read this carefully before
using the indicator.
FVX110 Fieldbus Segment Indicator thoroughly
tested at the factory before shipment. When taking
delivery of an instrument, visually check them
to make sure that no damage occurred during
shipment.
Also check that all indicator mounting hardware
shown in figure 2.1 is included. If the indicator is
ordered without the mounting bracket the indicator
mounting hardware will not be included. After
checking the indicator, carefully repack it in its box
and keep it there until you are ready to install it.

The following precautions must be observed when
storing the instrument, especially for a long period.
(a) Select a storage area which meets the following
conditions:
• It is not exposed to rain or subject to water
seepage/leaks.
• Vibration and shock are kept to a minimum.
• It has an ambient temperature and relative
humidity within the following ranges.
Storage ambient temperature:
–30 to 80°C
Relative humidity:
0% to 100% R.H.
Preferred temperature and humidity:
approx. 25°C and 65% R.H.
(b) When storing the indicator, repack it carefully
in the packaging that it was originally shipped
with.
2.4 Selecting the Installation
Location
The indicator is designed to withstand severe
environmental conditions. However, to ensure
that it will provide years of stable and accurate
performance, take the following precautions when
selecting the installation location.
(a) Ambient Temperature
Avoid locations subject to wide temperature
variations or a significant temperature gradient.
If the location is exposed to radiant heat from
plant equipment, provide adequate thermal
insulation and/or ventilation.
(b) Ambient Atmosphere
Do not install the indicator in a corrosive
atmosphere. If this cannot be avoided, there
must be adequate ventilation as well as
measures to prevent the leaking of rain water
and the presence of standing water in the
conduits.
