WARNING
CAUTION
WARNING
Misuse may cause the risk of death or serious
injury to persons.
CAUTION
Misuse may cause the risk of injury to persons
or damage to property.

Safety Precautions
WARNING
●Use F340A with correct supply voltage.
●Do not carry out the direct file of the commercial power supply to a signal input terminal.
●Carefully check wiring, etc. before applying power.
●Set the correct Excitation Voltage for the sensor. （10V is set when F340A is
dispatched from us.）
●Do not disassemble the main body for modifications or repair.
●Be sure to ground the protective ground terminal.
●When smoke, a nasty smell, or strange sound, please shut off a power supply
immediately and extract a power supply cable.
●Do not install in the following environments.
- Placeｓcontaining corrosive gas or flammable gas.
- Where the product may be splashed with water, oil or chemicals.

Safety Precautions
CAUTION
●Be sure to disconnect the power cable when performing the following.
- Attachment/detachment of connectors of options.
- Wiring/connection of cables to terminal blocks.
- Connection of the ground line.
●Take an interval of more than 5 seconds when repeating ON/OFF.
●For connection to the signal I/O terminal block, wire correctly after checking the signal
names and terminal block numbers.
Also, turn off the power of the main body before connection/wiring to the signal I/O
terminal block.
●Use shielded cables for the connection of strain gauge type sensor, displacement
sensor, External input and output or options.
●Take adequate shielding measures when using at the following locations.
- Near a power line.
- Where a strong electric field or magnetic field is formed.
- Where static electricity, relay noise or the like is generated.
●Do not install in the following environments.
- Where the temperature and/or humidity exceeds the range in the specifications.
- Places with large quantities of salt or iron powder.
- Where the main body is directly affected by vibration or shock.
●Do not use it, broken down.
●When you send F340A by repair etc., please take sufficient measures against a shock.
