INSTRUCTION SHEET
Thank you for selecting OMRON product. This sheet primarily
describes precautions required in installing and operating the product.
Before operating the product, read the sheet thoroughly to acquire
sufficient knowledge of the product. For your convenience, keep the
sheet at your disposal.
The mounting magnets provided with the product have
strong magnetism. If the product is mounted using these
magnets, anyone wearing a heart pacemaker must not
operate the product; or the product must not be in proximity
of such a person.
This product contains lithium batteries. Serious injury may
occur due to fire or explosion. Do not attempt to
disassemble the product, deform it by applying pressure,
heat it in a high temperature (100°C℃ or more), or burn it
for disposal.

Warning Indications
WARNING
CAUTION
A minor or moderate injury or property damage may occur
due to explosion. Do not use the product in an environment
containing an inflammable or explosive gas.
An electric shock may occur. Do not replace the batteries
when the unit is clamped to a conductor for measurement.
Observe the following precautions to ensure safe operation.
• Do not install the product in the places subject to exposure to water, oil, or chemical splashes.
• Only the provided AC adapter (not other) must be used when using AC power supply.
• If a voltage that exceeds the rated voltage is applied to the AC adapter, smoking may occur. Do
not connect a power supply that exceeds the rated voltage. In a situation where a voltage
higher than the rating is applied, use protective equipment so that the power supply voltage
does not exceed the rated voltage.
• Dispose of the product as industrial waste.
• Do not let the product drop or subject it to a shock, which may cause its damage or malfunc-
tion. Use screws to secure the product when mounting it on the wall. Stop using the product if
it has been applied with a strong impact.
• When inserting or removing an SD card, securely hold the product to prevent it from dropping,
which may cause a damage. Do the same when inserting or detaching an AC adapter, alarm
output cable, or sensor connector.
• Do not bring the product close to magnetic products (e.g. magnetic cards), sensitive electronics
equipment (e.g. computers or clocks), when the product is attached with the mounting magnets.
• Small pieces may be chipped off the mounting magnets when they are attracted to the surface.
Make sure the pieces do not enter the eyes. Consult a medical doctor if this happens.
• When using the mounting magnets to install the product, take caution not to allow a finger to
be caught between the product(s) and the magnetic surface.
• Do not install the product at a high place when using the mounting magnets.
• Apply an appropriate load to the alarm output terminals to prevent possible smoking.
• If liquid crystal leaks due to a damage to the LCD panel, take caution not to allow it to contact
your skin, to be inhaled or swallowed. If it has contacted your skin or entered your mouth, seek
medical attention.
• Take anti-static electricity measures (e.g. touching grounded metal object) when handling the
product.

PRECAUTIONS FOR SAFE USE
PRECAUTIONS FOR CORRECT USE
1. Avoid installing the product in the following places:
• Places exceeding the rated ambient temperature
• Places exposed to extreme temperature changes (where condensation occurs)
• Places subject to relative humidity exceeding the rated humidity range
• Places subject to corrosive or flammable gases
• Places subject to mist, droplets, coarse particles, fiber, salt, metal dust, or large amount of
particles
• Places subject to direct shock or vibration
• Places subject to direct sunlight
• Places subject to exposure to water, oil, or chemical splashes
• Places subject to strong magnetic field or electric field
• Outdoors
2. Wiring
• Wire the product cable separately from high-voltage or power lines. Placing them in the same
wiring or the same duct may cause induction, resulting in the product malfunction or damage.
• Make sure that the I/O terminals are inserted or removed with the power turned OFF. Doing
this with the power ON may result in a failure.
• When using a DC cable, connect the white-lined wire of the cable to the power input (24 VDC
± 3%) and the non-lined wire to 0V.
• Use a ferrite core to reduce the noise to/from other device when supplying power to the unit
via a DC cable. To use the provided DC cable, attach the provided ferrite core as shown
below.
3. Mounting screw holes
•
The screw holes provided on the product are M3 and 4 mm deep. Do not screw deeper than 4
mm, which may damage the product.
4. Operation
When using the product, also read KM series power sensor/monitor instruction sheets for
necessary information relevant to the product.
• The Power Sensors/Monitors that can be connected to the product are KM20-B40-FLK,
KM50-C, KM50-E, KM100, KM-N1-FLK, KM-N2-FLK and KM-N3-FLK.
To directly connect KM-N1-FLK, KM-N2-FLK and KM-N3-FLK to ZN-KMX21- , please
purchase a separately sold dedicated connection cable ZN9-KMC30-N.
5.Long Term Storage
If the product will not be used for a long period of time, store the product in the location
where the temperature is not too high. Otherwise the built-in battery may drain faster.
