CAUTION
Follow the instructions below to avoid risk of
personal injury or property damage.
Disconnect the power cord when performing the following.
o
When wiring or connecting cables to the terminal banks for connecting the DC power supply, load cells and external inputs
and outputs
o
When connecting the ground line
Wait for at least five seconds between turning the unit on and off.
Never touch the connectors while the product is turned on.
When connecting to a power supply, frame ground, signal input/output connector or D/A or RS-485 terminal bank, be sure to
wire them correctly after confirming the signal names and pin assignment numbers. Use shielded cables for signal input/output
cables (load cell, external input/output).
Before use, fix the cables separately so that they do not hang to prevent the connectors from being pulled out and to protect the
connectors from unnecessary pressure.
Conduct wiring in a place so that it will not be together or parallel with electrical wiring.
Avoid use in locations like the following.
o
Near a power line
o
Where a strong electric or magnetic field is present
o
Where static electricity or noise, (for example, from a relay) is generated
Do not install in the following environments.
o
Locations subject to temperatures exceeding the specified ranges for temperature and humidity
o
Locations subject to radiant heat from heat sources
o
Locations with high salt or iron content
o
Locations exposed to dirt and dust
o
Locations subject to direct vibration or shock
o
Locations subject to severe temperature changes
o
Outdoor, or locations with an altitude of higher than 2000 m
o
Locations where freezing or condensation might occur
Do not operate a damaged unit.
The unit is classified as an open-type (built-in) device and must be installed inside a control panel.
If the top cover or panel faces become dirty, wipe it gently with a soft cloth that has been slightly dampened with a diluted neu-
tral cleaning fluid and wrung out well. DO NOT use a chemically treated dust cloth, paint thinner, or other flammable solvents.
Using any of them could damage the coating of the product.
If the product is used in a manner unintended by the manufacturer, the user’s safety may be adversely affected.
Always attach the DC power terminal bank cover when an electric current is present.
If subject to electromagnetic waves (from transceivers, mobile phones, amateur wireless transmissions, etc.), use metal pipes for
the wiring or make other countermeasures using shielding.
