C3.2 Notes on Installation
Pay attention to the following points at the installation of YFGW510 and field wireless devices.
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.
l Vibration and Impact
Although the device is designed to be resistant to vibration and impact, an installation site
should be selected where vibration and impact are kept to a minimum.
n Installation of Explosion Proof Compliant Device
The explosion proof compliant equipment can be installed in the hazardous area of specific
gases. This device must be installed in accordance with the regulations of the country where the
device is installed.
• Installation: Check that the ambient temperature is not beyond the limit.
• Wiring: Put all the power cables in protective ducts. If possible, also put the network cables
(optical fiber cable or metal cable) in protective ducts.
• Maintenance: After confirming that there is no dangerous gas in the ambience, open the
housing or protective ducts.
