3. Safety Instructions and Precautions
3.1.
Safety Instructions on Intrinsically safe Structure
 Do not disassemble or modify the scale.
 When determining the installation site, take the following into consideration.
Will explosive gases be generated? How often will they be generated?
Refer to “6. CONFORMING STANDARDS.”
 A portion of the enclosure is non-conducting and, under certain extreme conditions,
may generate an ignition-capable level of electrostatic charges. The user shall
ensure that the equipment is not installed in a location where it may be subjected to
external conditions (such as high-pressure steam) which might cause a build-up of
electrostatic charges on non-conducting surfaces. Additionally, cleaning of the
equipment should be done only with a damp cloth.
 Replace the batteries in non-hazardous areas.
 As a power source, only the four “D”, “LR20” or “AM1” alkaline 1.5 V batteries listed
below can be used.
DURACELL MN1300, ENERGIZER E95, Panasonic LR20(XJ)

All 4 cells in single platform scale must be by the same manufacturer.

When replacing the batteries, be sure to prevent foreign materials from entering the
battery compartment.
 The enclosure contains aluminum and is considered a potential risk of ignition by
impact or friction. Care must be taken during installation to prevent impact or
friction.
3.2. Precautions on Installing the Scale
Consider the following conditions to get the most from your scale.
Install the scale where the temperature and relative humidity is stable, there is no draft
and a stable power source is available.
Install the scale on a solid and level surface.
Do not install the scale in direct sunlight.
Do not install the scale near heaters or air conditioners.
Do not install the scale where there is corrosive gas present.
Do not install the scale near equipment which produces magnetic fields.
Do not install the scale where there is apt to be static electricity, in a place where the
relative humidity is lower than 45% RH. Plastic and isolators are apt to be charged with
static electricity.
The display unit is not water resistant. Use the display unit cover to avoid damage.
Do not use an unstable power source.
Remove the protective film from the weighing pan before use.
