Safety Precautions
These safety precautions are intended to help you to use the product safely and correctly,
and to prevent injury to yourself or others as well as damage to property. Be sure to follow
all safety precautions. Please also read and understand this manual carefully before at-
tempting to do any installation, wiring, or maintenance.
The product warranty will be void if it is used in a way not specified.
Installation Precautions
Warning
Use this product within the limits of the described usage conditions (explosion proofing, pressure
rating, temperature, humidity, voltage, vibration, shock, installation orientation, ambient atmosphere,
and the like). Usage outside of these limits can cause instrument failure or fire, resulting in a danger of
scalding or other harm.
Explosion-proof models should be installed so that the device's temperature stays below the upper
limit. If this temperature is exceeded, explosion-proof functioning cannot be guaranteed. Comply
with the ambient temperature and wetted temperature requirements, and if necessary, adopt an
insulation solution or select a place with good ventilation.
When working in an explosion-hazard area, perform installation and implementation according to the
methods prescribed by the hazard guidelines.
For explosion-proof models, be sure to use the provided (specified) flameproof packing cable gland
for the signal wiring port of the device. Using anything other than the supplied (specified) component
will jeopardize the explosion-proof function.
If changing the wiring orientation for an explosion-proof model, use the supplied (specified) elbow joint.
Using anything other than the supplied (specified) component will jeopardize the explosion-proof function.
To ensure safety, have a qualified person with specific technical expertise in instrumentation work, electrical
work, etc., perform the installation, wiring, and the like. There is a risk of electric shock during the process.
Use a power supply for this product which has overcurrent protection.
When installing the product, make sure that the gaskets do not stick out at the connections with the
process (connections between adapter flanges and flanges). There is a danger that the process fluid
will leak out and cause scalding or other harm.
When fastening a flange-mount transmitter or remote-seal transmitter to the flange, tighten the
bolts, etc., evenly to the specified tightening torque. If they are not properly tightened, there is a
danger that the process fluid will leak out and cause scalding or other harm.
If the process fluid is harmful to humans, take safety countermeasures by wearing goggles, a mask,
etc. There is a danger of scalding or other harm if it gets on the skin or in the eyes, or if it is inhaled.
The threads on this device and on the process pipes should conform to the same standard. If different
standard threads are connected, there is a danger that the process fluid will leak out and cause
scalding or other harm.
If the connecting thread of a direct-mount transmitter is a parallel thread, use the gasket supplied
with the product. If a gasket is not used, or a gasket other than the supplied gasket is used, there is a
danger that the process fluid will leak out and cause scalding or other harm.
If the connecting thread of a direct-mount transmitter is tapered, wind sealing tape around it. Without
sealing tape, there is a danger that the process fluid will leak out and cause scalding or other harm.
If the connecting thread of a direct-mount transmitter is tapered, do not loosen it after it has been
tightened. There is a danger that the process fluid will leak out and cause scalding or other harm.
Before starting to use this device, check to make sure the vent plug and drain plug are closed.
Be sure to take safety precautions while working.
