Safety Precautions

!CAUTION
Do not touch the terminals while power is being supplied.
Doing so may possibly result in electric shock.
Do not allow pieces of metal, wire clippings, or fine
metallic shavings or filings to enter the product. Doing so
may occasionally result in minor or moderate injury or in
property damage due to electric shock, fire, or
malfunction caused by internal short circuiting.
Do not use the product in locations where flammable or
explosive gases are present. Doing so may occasionally
result in minor or moderate explosion, causing minor or
moderate injury, or property damage.
Do not use the equipment for measurements within
Measurement Categories II, III, or IV (according to IEC
61010-1). Doing so may occasionally cause unexpected
operation, resulting in minor or moderate injury, or
damage to the equipment. Use the equipment for
measurements only within the Measurement Category for
which the product is designed.
Failure to perform correct setting of the product according
to the application may occasionally cause unexpected
operation, resulting in minor or moderate injury, or
damage to the equipment. Ensure safety in the event of
product failure by taking safety measures, such as
installing a separate monitoring system.
Product failure may occasionally prevent operation of
comparative outputs, resulting in damage to the
connected facilities and equipment. Ensure safety in the
event of product failure by taking safety measures, such
as installing a separate monitoring system.
Tighten the screws on the terminal block and the
connector locking screws securely using a tightening
torque within the following ranges. Loose screws may
occasionally cause fire, resulting in minor or moderate
injury, or damage to the equipment.
Terminal block screws: 0.43 to 0.58 N·m
Do not attempt to disassemble, repair, or modify the
product. Doing so may occasionally result in minor or
moderate injury due to electric shock.

Precautions for Safe Use

Environmental Precautions

1. Do not use the product in the following locations.
• Locations subject to direct radiant heat from heating equipment
• Locations where the product may come into contact with water or
oil
• Locations subject to direct sunlight
• Locations where dust or corrosive gases (in particular, sulfuric or
ammonia gas) are present
• Locations subject to extreme temperature changes
• Locations where icing or condensation may occur
• Locations subject to excessive shocks or vibration
2. Do not use the product in locations subject to temperatures or
humidity levels outside the specified ranges or in locations prone
to condensation. If the product is installed in a panel, ensure that
the temperature around the product (not the temperature around
the panel) does not go outside the specified range. Parts life is
dependent on temperatures. A part life shortens when the
temperature rises, and it lengthens when the temperature falls.
Parts life can be lengthened by lowering the temperature inside
the product.
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 in the same cable as
power lines. Other measures for reducing noise include running
lines along separate ducts and using shield lines.
4. Do not install the product near devices generating strong high-
frequency waves or surges. When using a noise filter, check the
voltage and current and install it as close to the product as
possible. If several products are mounted side-by-side or
arranged in a vertical line, the heat dissipation will cause the
internal temperature of the product to rise, shortening the service
life. If necessary, cool the products using a fan or other cooling
method.
5. Take care when cleaning the product, because the exterior of the
product may be damaged by organic solvents (thinner, benzine,
etc.), strong alkaline materials and strong acid materials.
6. Avoid storing in high humidity or in a corrosive gas environment
(including during transportation)
