WARNING
• Damage to the Protection
Operating the product in a manner neither
described in this manual nor the applicable manuals
listed in the front page may damage the product's
protection.
• Installation, Wiring, and Maintenance
• The magnetic flowmeter is a heavy product. Be
careful that no damage is caused personnel
through accidentally dropping it, or by exerting
excessive force on the magnetic flowmeter. When
moving the magnetic flowmeter, always use a
trolley and have at least two people carry it.
• When the magnetic flowmeter is processing hot
fluids, the product itself may become extremely
hot. Take sufficient care not to get burnt.
• Where the fluid being processed is a toxic
substance, avoid contact with the fluid and avoid
inhaling any residual gas, even after the product
has been taken off the piping line for maintenance
and so forth.
• Do not apply excessive weight, for example, a
person stepping on the magnetic flowmeter.
• Installation, wiring and maintenance of the
magnetic flowmeter must be performed by expert
engineer or skilled personnel. No operator shall
be permitted to perform procedures relating to
installation, wiring and maintenance.
• The magnetic flowmeter must be installed within
the specification conditions.
• The magnetic flowmeter should be installed away
from 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 more.
• When wiring the conduits, pass the conduit
through the cable entry, and utilize the waterproof
gland to prevent water from flowing in. Install a
drain valve at the low end of the vertical pipe, and
open the valve regularly.
• When opening and closing the cover, be sure
to handle the 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
flowmeter.
• 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:
15 A, conforming to IEC60947-1, IEC60947-2
and IEC60947-3). Locate this switch either near
the product or in other places facilitating easy
operation. Affix a "Power Off Equipment" label to
this external switch or circuit breaker.
