WARNING
• Installation, Wiring, and Maintenance
• Theowmetershouldbeinstalledawayfrom
electrical motors, transformers, and other power
sources in order to avoid interference with
measurement.
• In cases where the ambient temperature exceeds
50°C, use external heat resistant wiring with
a maximum allowable temperature of 70°C or
above.
• When wiring the conduits, pass the conduit
through the wiring connection port, and utilize the
waterproofglandtopreventwaterfromowingin.
Install a drain valve at the low end of the vertical
pipe, and open the valve regularly.
• When opening and closing the transmitter cover,
be sure to handle the transmitter cover carefully
so that there are no damage and foreign matter
adhesion at its threads and O-ring.
• Do not open the cover in wet weather or humid
environment. When the cover is open, stated
enclosure protection is not applicable.
• Do not connect cables outdoors in wet weather
in order to prevent condensation and to protect
the insulation, e.g. inside the terminal box of the
owmeter.
• Ensure that the power supply is off in order to
prevent electric shocks.
• When opening the terminal box, wait for more
than 20 minutes after turning off the power.
• Install an external switch or circuit breaker as a
means to turn the power off (capacitance: 15A,
conforming to IEC60947-1 and IEC60947-3).
Locate this switch either near the instrument or
inotherplacesfacilitatingeasyoperation.Afx
a "Power Off Equipment" label to this external
switch or circuit breaker.
• Wiring work should be done adequate wire,
sleeve crimp and torque force. Use terminal with
insulating cover for the power supply wiring and
protective grounding wiring. Do not pull the wires
too much strongly in order to prevent electric
shocks caused by their damage.
• This instrument employs the parts which are
affected by a function damage caused by static
electricity. Thus, you should do the antistatic
work using an anti-static wrist band for it and be
careful to avoid touching each electrical parts and
circuitry directly.
• When connecting the wiring, check that the
supply voltage is within the range of the voltage
speciedforthisinstrumentbeforeconnectingthe
power cable. In addition, check that no voltage is
applied to the power cable before connecting the
wiring.
• To prevent electric shocks, ensure the electrical
wiring cover is completely attached after the
wiring work.
• To prevent electric shocks, do not impress over
rated voltage to each input/output terminals.
WARNING
• If there is any unused cable entry, use the
blanking plug to cover which comes with this
instrument or which is supplied by YOKOGAWA.
The blanking plug should be fastened into the
unused cable entry without any mistake. If not,
stated enclosure protection is not applicable.
• Maintenanceofthisowmetershouldbe
implemented in a maintenance service shop
where the necessity tools and environment
condition are provided.
The necessity of this environmental condition
is that ambient temperature is 5 to 40°C
(the maximum relative humidity is 80 % for
temperature 5 to 31°C, and decreasing linearly to
50 % relative humidity at 40°C).
• All procedures relating to installation must comply
with the electrical code of the country where it is
used.
CAUTION
This instrument is a Class A instrument in the
EN61326-1(EMC standard). Operation of this
instrument in a residential area may cause radio
interference, in which case the user is required to take
appropriate measures to correct the interference.
