Precautions during wiring
Warning
To avoid severe accidents, make sure to read and understand the
followings and use the instrument.
Electric shock may occur, make sure to turn OFF the power and perform
the panel mounting and/or wiring operation.
Wiring operation should be done by professional
Wiring should be done by a person having actual experience and basic knowledge of instrumentation.
Mount the terminal cover
In order to ensure safety, after the wiring is done, take measures so as to prevent direct contact with the
terminal of the product.
Exclusive terminal cover of the instrument is available as accessory (Sold separately).
Keep away from strong power circuit and noise sources
In order to prevent adverse effect due to noise, do not place the instrument near a device from which
noise is generated (magnet relay, motor, thyristor regulator, inverter etc.). Also avoid passing the wiring of
the instrument and that of noise generating devices through the same duct. Always keep the wiring away
from each other. Take the necessary countermeasures against noise.
Keep away from the heat generating sources
In order to prevent adverse effect due to high temperature, do not place the instrument near the heat
generating sources. If the instrument is kept near any heat generating source, measurement goes wrong
and finally the life of the instrument is shortened. Pay attention to the surrounding temperature of the
instrument.
Avoid places where there is wind and sudden temperature change, it also causes an error in
measurement. Take necessary measures to avoid such surrounding environment.
Unused terminals
Do not connect anything to the unused terminal. Instrument may get out of order.
Countermeasures against erroneous output at the power ON
When power is ON, sometimes the output related signal may be momentarily output when the instrument
is starting normally. Take necessary countermeasures by using an external circuit.
