Caution on Wiring
CAUTION
•
When performing wiring termination to prevent output trouble caused by
moisture, dew condensation or water leak, follow “Section 3.3. Flow
transmitter wiring” described in this manual
•
Before performing the wiring work, be sure to turn OFF the main power to
prevent electric shocks.
•
Do not perform wiring work outdoors in rainy days to prevent insulation
deterioration and dew condensation. Otherwise, it can result in trouble,
malfunction, etc.
•
Be sure to connect a power source of correct rating. Connection of a
power source of incorrect rating may lead to a risk of fire.
•
The unit must be earthed as specified to prevent electric shocks or
malfunction.
•
The analog output signal cable should be wired as far away as possible
from high-voltage lines to prevent entry of noise signals as it will cause
malfunction of the unit.
•
To prevent malfunction of the unit, the analog output signal cable and
power cable should be wired using separate conduits.
Caution on Maintenance/Inspection
CAUTION
•
The unit should be inspected everyday to always obtain good results of
measurements.
•
When measuring the insulation resistance between the power/output
terminal and the case, follow “Section 5.2.4. Measuring insulation
resistance” described in this manual.
•
If the fuse is blown, detect and eliminate the cause, and then replace the
fuse with a spare. If there are no spares, replace the fuse with the one
specified in this manual (that must be prepared by customer). Use of a
fuse other than specified or its short-circuit may cause an electric shock or
fire. The fuse should be replaced according to “Section 5.3. Replacing
fuse” described in this manual.
