01. Fail-safe device must be installed when using the unit with machinery that
may cause serious injury or substantial economic loss. (e.g. nuclear power
control, medical equipment, ships, vehicles, railways, aircraft, combustion
apparatus, safety equipment, crime/disaster prevention devices, etc.)
Failure to follow this instruction may result in personal injury, economic loss or fire.
02. Do not use the unit in the place where flammable/explosive/corrosive gas,
high humidity, direct sunlight, radiant heat, vibration, impact, or salinity
may be present.
Failure to follow this instruction may result in explosion or fire.
03. Do not disassemble or modify the unit.
Failure to follow this instruction may result in fire.
04. Do not connect, repair, or inspect the unit while connected to a power
source.
Failure to follow this instruction may result in fire.
05. Check 'Connections' before wiring.
Failure to follow this instruction may result in fire.
᜸ Caution
Failure to follow instructions may result in injury or product damage.
01. Use the unit within the rated specifications.
Failure to follow this instruction may result in fire or product damage.
02. Use a dry cloth to clean the unit, and do not use water or organic solvent.
Failure to follow this instruction may result in fire.
03. Do not supply power without load.
Failure to follow this instruction may result in fire or product damage.
Cautions during Use
• Follow instructions in 'Cautions during Use'.
Otherwise, it may cause unexpected accidents.
• 12-24 VDCᜡ power supply should be insulated and limited voltage/current or Class 2,
SELV power supply device.
• Use the product, after 0.8 sec of supplying power.
• Wire as short as possible and keep away from high voltage lines or power lines, to
prevent surge and inductive noise.
Do not use near the equipment which generates strong magnetic force or high
frequency noise (transceiver, etc.).
In case installing the product near the equipment which generates strong surge (motor,
welding machine, etc.), use diode or varistor to remove surge.
• If the surface of the product is rubbed with a hard object, PTFE coating can be worn
out.
• This unit may be used in the following environments.
- Indoors (UL Type 1 Enclosure)
- Altitude max. 2,000 m
- Pollution degree 3
- Installation category II
Cautions for Installation
• Install the unit correctly with the usage environment, location, and the designated
specifications.
• Do NOT impacts with a hard object or excessive bending of the wire lead-out. It may
cause damage the water resistance.
• Do NOT pull the Ø 3.5 mm cable with a tensile strength of 25 N, the Ø 4 mm cable with
a tensile strength of 30 N or over and the Ø 5 mm cable with a tensile strength of 50 N
or over. It may result in fire due to the broken wire.
• When extending wire, use AWG 22 cable or over within 200 m.
