Precautions for Safe Use
(1) Do not store, install, or use the Product in the following locations:
• Outdoor or locations subject to direct sunlight
• Locations subject to rain and wind damage
• Locations subject to excessive vibration or shock
• Locations subject to rapid temperature changes
• Locations prone to icing and dew condensation
• Locations subject to water or oil
• Locations subject to dust or corrosive gases (particularly sulfurizing
gases, ammonia, etc.)
• Locations subject to influence of static electricity and noise
• Locations subject to bugs and small animals
• Locations subject to electromagnetic fields
• Locations subject to a load
(2) A switch or circuit breaker should be provided close to this unit. The
switch or circuit breaker should be within easy reach of the operator,
and must be marked as a disconnecting means for this unit.
(3) Mount the Product in the correct direction for installation.
(4) Use and store the product in a location where the ambient
temperature and humidity are within the specified ranges. If
applicable, provide forced cooling.
(5) Be sure to use terminals of operation power supply carefully,
because they have hazardous voltage.
(6) Use the wire given in this manual.
(7) When wiring, wire by enough length.
(8) Make sure that the operation power supply voltage and the load
voltage and current are within the specifications of the Product.
(9) Check terminal polarity when wiring and wire all connections
correctly. Do not wire the input and output terminals incorrectly.
(10) Make sure the crimp terminals for wiring are of the specified size.
(11) Do not wire anything to the release holes.
(12) Confirm the wiring the input and output terminals correctly before
power is supplied.
(13) The terminal block may be damaged if you insert a flat-blade screwdriver
in the release hole with excessive force. When inserting a flat-blade
screwdriver into the release holes, operate with a force of 15·N or less.
(14) To prevent inductive noise, wire the lines connected to the Product
separately from power lines carrying high voltages or currents. Also,
do not wire in parallel with or on the same cables as power lines.
Other measures for reducing noise are to separate from ducts
including noisy lines.
(15) The Product may be subject to radio disturbances. Do not install the
Product near equipment that generates high frequencies or surges.
(16) The maximum terminal temperature is 65°C. Use wires with a heat
resistance of 65°C min to wire the terminals.
(17) For accurate measurement of the Product, use the range suitable for
the measurement voltage and current.
(18) Periodically check that the LCD display and LED indicators operate
correctly. Depending on the operating environment, the display or
indicators may fail due to deterioration.
(19) Do not exceed the communications distance that is given in the
specifications and use the specified communications cable. As for
the requirements on the communication distance and the cable, refer
to K7DD User's Manual (Cat. No. N233.
(20) Do not continue to use the Product if the front surface peels.
(21) The alarm output function is a function for the output of an alarm
when the set threshold value is exceeded. Do not use this function
for control, etc.
(22) Use this product inside the control panel to prevent external noise.
(23) When discarding the Product, properly dispose of it as industrial waste.
(24) Always use the special CT that is specified by OMRON' s model number.
(25) Clamp the wire of the special CT correctly. After clamping, make
sure until it clicks into place.
(26) The measurement accuracy may deteriorate due to the influence of
external magnetic fields. Install the special CT as far away as
possible from electric wires with large current flows, except for those
to be measured.
(27) Connect the special CT input and the voltage input correctly to the
same application.
(28) Install equipment so that wiring cables do not touch moving parts.
(29) Do not build a system that judges the open/closed state of the valve
based on the measurement value of the Product. A system error
may occur.
(30) If you accidentally drop the Product, the inside of the Product may
be damaged, so do not use it.
(31) Do not bend a wire past its natural bending radius or pull on it with
excessive force. Doing so may cause wire disconnection, or damage
to the terminal block.
(32) Do not wire anything to the release holes.
Precautions for Correct Use
(1) During periodic inspection, installation of an additional sensor, or
adjustment of sensor position, use the Product after ensuring that
correct operation can be performed.
(2) Do not use the product as a safety apparatus, or for the rescue of
human lives.
(3) Confirm that wire does not stick up after wiring of stranded cable.
(4) In crossover wiring, connecting more than one K7DD in parallel may
allow a large amount of current to flow. Keep the current to 10 A or
less per terminal.
(5) When wiring a ferrule terminal or single wire, push it directly into the
terminal hole.
When wiring a stranded wire, insert the wire into the terminal hole
while pushing straight along the taper of the release hole with the
recommended flat-blade screwdriver.

(6) The terminal block may be damaged if specialized tool is not used.
Use a recommended flat-blade screwdriver to insert into a release
hole on the terminal block.
(7) Only a professional with an understanding of electricity and electric
devices must handle it. Read this manual carefully before using the
Product.
(8) Use the power supply voltage, input power, and other power
supplies and transformers with suitable capacities and rated outputs.
(9) Do not install the product close contact with the heating element.
(10) Use a power supply that will reach the rated voltage within 1 second
after the power is turned ON.
(11) Do not install the product near equipment that generates high
frequencies or surges.
(12) Make sure that the setting values registered in the Product match
the specifications of the load and special CT that are actually used.
(13) Do not ground the terminal on the output side of the special CT.
Failure to do so may result in unstable measurement.
(14) Do not directly clamp the special CT to the lines exceeding 600 VAC.
(15) If an error occurs during the operation of the Product, stop the operation
immediately and make suitable corrections such as replacement.
(16) Do not use any liquids such as paint thinner, similar solvents or
alcohol to clean the Product. Clean it with a soft, dry cloth.
