Warning
Never disassemble, repair or retrofit the
product.
It might exclude the product
from the quality assurance and cause
the damage to devices, electric shock or
fire.
Ensure the power plug to be fully
inserted to prevent shaking.
Any instable connection might cause
electric sparks to set fire.
Ensure the grounding of the product.
Poor grounding might cause failure or
electric shock upon electric leak. .
Do not damage, process,
excessively jerk, bend or twist the
power cord.
It might damage the power cord to
cause fire or electric shock.
Keep any combustible spray or fire
source away.
It might cause fire.
Do not spray water to the outside of the
product or use it in any humid place.
It might deteriorate the insulation of
electric parts that can cause the electric
shock, fire risk or weighing errors.
Do not place the product to the direct
sunlight or near any hot object like a
heater.
It might cause fire.

Attention
Check the weighing error anytime for
the accurate weighing.
Any use out of the allowed tolerance
for the careless use or other causes
might not ensure the accurate
weighing.
Avoid any sudden shock to the product.
It might damage the product to fail the
accurate weighing.
Find a proper place to attach the rubber
pad at the bottom of the indicator,
which was shipped together.
Do not use the product at a place with
sudden temperature changes or severe
vibrations.
It might cause the weighing error or
failure.
Do not install the produce at a place with the excessive electromagnetic wave.
It might cause the wrong weighing.

1.2 Transport, assembly and installation
1.2.1. Transport
(1) Packaging method and specification
(a) After removing any external/internal foreign matter on the product, clean, dry and apply
corrosion preventive treatment on exposed sections.
(b) Measures are needed to prevent foreign matter from entering openings within the product.
(c) The packaging must correspond with the size and weight of the contents, and internal
fillings that can act as a buffer must be used such as air caps or newspapers.
(d) The product must be appropriately protected to prevent rust and corrosion.
(2) Transport Method
If stacked high during transportation, there is possibbility of damage by fall due to the weight of
the product. Therefore suitable protective equipment or devices must be used when transporting.

1.2.2.Assembly and Installation
(1) Assembly
This product is fully assembled when shipped and there is no need of separate assembly by
the user.
(2) Installation
When installing electrical instruments in an explosion-proof area, compare the below
requirements with the technical specifications beforehand to confirm correspondence.
(a) Normal Requirements.
①Use installation method (floor installation, wall installation etc.) and installation form
(slope allowance etc.) that is appropriate with the explosion prevention electric
instrument's usage conditions.
②Bolts, nuts, metallic etc. used in the installation must have sufficient mechanical
strength. Also, use materials and surface treatment that is clearly based on installation
location.
③Ensure recharge sections are not exposed.
(b) Installation Location
①Install where it is convenient to operate, manipulate, adjust, maintain etc.
②If possible avoid locations exposed to moisture or humidity and avoid high humidity
areas.
③If possible avoid areas of corrosive liquid dispersion and near release of corrosive gas.
④Avoid locations close to high temperature heating elements such as heat pipes, steam
pipe etc. and areas of rapid temperature fluctuation.
⑤Avoid locations that is heavily affected by vibrations from mechanical devices etc.
⑥Do not install in locations of high pressure or heavy electric noise.
⑦Do not install in location of strong direct sunlight.
(c) Installation method must be suitable to the purpose.
(d) Power connection and wiring.
①Use a cable with internal ground wire for the power line and install separately from
the signal line.
②Connect the power cord with the power socket in an explosion proof area and when
connecting in an explosive area always connect using "plugs and receptacles'.
③Connect the power and signal lines through a designated location. (Refer to 4.2.2)

11
(e) Wiring Method during Installation (power and load cell)
①Refer to "4. External Explanation" and "5. Internal Explanation" of this manual.
②Use an Allen wrench to loosen the front bolts and open the front cover
③Connect an appropriate cable gland (joint screw diameter(M20*1.5)) to the power line. (Refer to 4.2
Front Surface Explanation)
④Connect the power line to the power terminal as depicted in the figure below. Refer to this
manual's "5.1.1 Power Connector" for the wiring order. (Connect the power line using a 4Φ
terminal etc.)
