1. HANDLING PRECAUTIONS
1.3 Storage Precautions
(1) Select a storage place :
• Which is protected from rain and water.
• Which is free from vibration and impact.
• Whose temperature and humidity are as specified
below. Room temperature and humidity (approx.
25
°C and 65%) are more recommendable.
Temperature: -10 to 60
°C
Humidity: Less than 80%
(2) Store the converter in the packing condition of
shipment from YOKOGAWA whenever possible.
1.4 Precautions for Installation
Area
To use the converter stably for a long time, determine
an installation place, taking into account the following.
(1) Ambient Temperature
Avoid installing the instrument in a place subject to a
large temperature gradient and variations. If the
instrument is subject to plant-generated heat radiation,
take measures such as provision of heat protection and
good ventilation.
(2) Atmospheric Conditions
Avoid installing the converter in corrosive atmosphere.
Should it be used in corrosive atmosphere, make
provision for maintaining good ventilation.
(3) Magnetic Field
Please contact us in the case this instrument is installed
the strong Magnetic Field.
