A3.1.2 Notes on Installation
Pay attention to the following points at the installation of YFGW710.
n Installation Location
This device is designed to work under the severe environmental condition. However, it is neces-
sary to pay attention to the following conditions for the stable and long-term precise operation.
l
Exposure to Direct Sunlight
If the device is placed at a location that may be exposed to direct sunlight, it is necessary
to make the insulation measure. However, the antenna must be covered with the material
which does not block the radio wave.
l 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. Do not install the device in a location where high temperature
and high humidity may last for a long time.
l Ambient Atmosphere
Do not install the device in a corrosive atmosphere. If this cannot be avoided, there must
be adequate ventilation as well as measures to prevent the rain water from penetrating or
remaining in the conduits.
