Precautions for Correct Use

(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 the 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 more than 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 operations can be performed normally.
(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.
