Safety Considerations

Observe all ‘Safety Considerations’ for safe and proper operation to avoid hazards.
symbol indicates caution due to special circumstances in which hazards may occur.

Warning Failure to follow instructions may result in serious injury or death.

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.
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.
Install on a device panel to use.
Failure to follow this instruction may result in fire or electric shock.
Do not connect, repair, or inspect the unit while connected to a power source.
Failure to follow this instruction may result in fire or electric shock.
Check ‘Connections’ before wiring.
Failure to follow this instruction may result in fire.
Do not disassemble or modify the unit.
Failure to follow this instruction may result in fire or electric shock.

Caution Failure to follow instructions may result in injury or product damage.

Use the unit within the rated specifications.
Failure to follow this instruction may result in fire or product damage.
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 or electric shock.
Keep the product away from metal chip, dust, and wire residue which flow into the unit.
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.
When supplying or turning off the power, use a switch or etc. to avoid chattering.
Install a power switch or circuit breaker in the easily accessible place for supplying or disconnecting the power..
In order to block peripheral current, use isolation transformer which of secondary part is not grounded to supply power to the external input device.
After turning off the power, change the time range, etc.
Do not connect two or more timers with only one input contact or transistor simultaneously.
Keep away from high voltage lines or power lines to prevent inductive noise. In case installing power line and input signal line closely, use line filter or varistor at power line and shielded wire at input signal line.
Do not use near the equipment which generates strong magnetic force or high frequency noise.
This unit may be used in the following environments.
– Indoors (in the environment condition rated in ‘Specifications’)
– Altitude max. 2,000 m
– Pollution degree 2
– Installation category II
