Safety Precautions

Precautions for Safe Use
The following precautions are essential to ensure safety. Always heed
these precautions.
1. Do not use or store the Product in the following locations.
• Outdoors or in locations subject to direct sunlight, wind, or rain
• Locations subject to dust, metal powder, or corrosive gases (in
particular, sulfuric or ammonia gas)
• Locations subject to static electricity or noise
• Locations subject to flooding or exposure to oil
2. Use DIN Track for installation and mount the Product in the correct
direction.
3. Do not touch the terminals when power is being supplied. Electric
shock may occasionally occur.
4. Be sure you understand the contents of the Instruction Sheet and
User's Manual and handle the Product according to the
instructions provided.
5. Check all terminal numbers and polarity when wiring and wire all
connections correctly.
6. Tighten terminal screws to the following torque.
Power supply terminals: 0.5 N·m
7. Use the Product within the specified temperature and humidity
ranges.
8. Do not use the product in locations subject to flammable or
explosive gases. Explosions may occasionally occur if the product
is used in such locations.
9. Do not install the Product in any way that would place a load on it.
10.Use the Current Transformer specified by OMRON.
11.Install an external switch or circuit breaker that complies with
applicable IEC60947-1 and IEC60947-3 requirements and label it
clearly so that the operator can quickly turn OFF the power.
12.The product must be handled by personnel who have knowledge
of electrical systems.
Precautions for Correct Use
The following precautions are essential to ensure correct use. Always
heed these precautions.
1. Do not use the product in the following locations.
• Places subject to radiant heat from heat generating devices.
• Places subject to vibrations or physical shocks.
2. Make sure to use setting values appropriate for the controlled
object. Failure to do so can cause unintended operation, and may
result in accident or corruption of the product.
3. Do not use thinner or similar solvent for cleaning. Use commercial
alcohol.
4. When discarding, properly dispose of the product as industrial
waste.
5. To measure correct values, perform aging for approximately 15
minutes.
6. Only use this product within a board whose structure allows no
possibility for fire to escape.
Installation
1. When wiring, use only recommended crimp terminals.
2. Do not block areas around the product for proper dissipation of
heat. (If you do not secure space for heat dissipation, life cycle of
the product will be compromised.)
Mounting the K8AC-H
• Pull down the hook on the bottom of the K8AC-H, and then catch
the hook on the top of the K8AC-H onto the DIN Track and press
the K8AC-H onto the DIN Track until it locks into place.
Removing the K8AC-H
• Pull down on the hook with a flat-blade screwdriver and lift up on
the K8AC-H.
Noise Countermeasures
1. Do not install the product near devices generating strong high
frequency waves or surges.
2. When using a noise filter, check the voltage and current and install
it as close to the product as possible.
3. In order to prevent inductive noise, wire the lines connected to the
product separately from power lines carrying high voltages or
currents. Do not wire in parallel with or on the same cable as power
lines.
Other measures for reducing noise include running lines along
separate ducts and using shield lines.
Wiring
• Do not touch terminals or perform wiring while power is supplied to
the product. Doing so may result in injury or malfunction.
• Wire to the correct terminal number. Incorrect wiring may result in
damage to or burning of components.
Wiring the Screw-less Clamp Terminals
• Directly insert the ferrule in the hole of the terminal to be wired.
Removing Wires from the Screw-less Clamp Terminals
• Insert the recommended flat-blade screwdriver straight into the
hole to pull out the wire.
