(24) Do not mount the way that the force is directly applied to the fitting part of the connector or the root
part of the cable connection. It may result in connector damage or cable disconnection.
(25) When bending cables, use cables with a minimum bending radius of 25 mm.
(26) Use preamplifier after it is fixed on the DIN rail or with screws. In case of using unfixed one, it is in
the condition that force is easily applied to the cable, and the cable may be broken.
(27) About oil-resistance of sensor head/cable; (Not tested by UL)
Follow the procedure below in case of using the product under the condition that uses cutting oil
since the life expectancy and the performance of the product are affected.
• Use the product in the specified condition for cutting oil
• Use the product at the dilution rate of cutting oil that is recommended by the cutting oil makers.
• Do not use the product in oil or water.
There are cases that the influence on the life expectancy of the product differs depending on the
type of the use oil. Make sure in advance that there is no deterioration of the sealing material by the
cutting oil, before using the product.
(28) Do not use the alarm output function for control. This function can be used only to detect abnormal
conditions and to output the alarm.
(29) Avoid using the product in places near a radio, a television set, or a wireless device.
The product may result in radio disturbance for these devices.
The followings are only for K6CM-IS.
(30) Do not clamp directly to the lines exceeding 480 VAC. UL certification complies with 480 VAC.
(31) Use the special ZCT (IRT) after fixing it with screws. If used without fixing, a load is easily applied
on the cable, and the cable may become disconnected.
(32) ZCT (IRT) is an special product. Do not use it for any other purposes. Otherwise, failure may occur.
(33) When clamping wires with special ZCT (IRT), do it in a right direction. If clamped in the wrong
direction, correct measurement cannot be taken.
(34) The distorted ratio of the input waveform should be 30% or less. If it is used in a circuit with large
distortion of waveform, it may cause unnecessary operation.
(35) Do not use in a circuit with the waveform is distorted. The error will increase due to the influence of
the distorted waveform.
The followings are only for K6CM-CI2.
(36) Make sure that the rating of the used special CT and the special CT setting of the product agree.
(37) Do not ground the special CT. Doing so may cause instability when measuring failure.
(38) Do not clamp directly to the lines exceeding 600 VAC. UL certification complies with 480 VAC.
(39) Place the cable between the special CT and the product at a distance of 6 mm or more from other
cables.
(40) Associated leads of the special CT shall be maintained within the same overall enclosure.
(41) The special CT are intended for installation within the same enclosure as the equipment. These
may not be installed within switchgears and panel boards.
