1-1 Precautions
■
No disassembling or modification.
Unless specifically stated in this document, disassembling or modification of this product,
mounting or removal of an undesignated component no longer maintains the function of the
safety structure or explosion-proof structure, leading to a serious accident or physical injury.
■
Battery replacement absolutely unacceptable.
Never replace the battery built in this product by any means. The function of the
explosion-proof structure will be no longer maintained, leading to a serious accident or
physical injury.
■
Install the power supply box in “non dangerous location”.
Installing the power supply box in a dangerous place will cause trouble such as an explosion
or a fire.
■
Connect the grounding terminal and cables properly.
Improper connection of the grounding terminal and cables will cause trouble such as an
explosion or a fire.
■
Keep Scale cable and DC power supply cable away from electromagnetic
source.
It may generate dielectric EMF, which degrades the intrinsic safety explosion-proof property
of the product and may lead to an explosion.
■
Install Scale cable and DC power supply cable properly so as to prevent
dielectric EMF.
Improper installation of them may impair the intrinsic safety performance of the product due
to the electrostatic induction, and electromagnetic induction and may lead to an explosion.
■
Do not replace fuse, optional slots of the power supply box or access to
the AC power terminal when the AC power cord is connected to the mains
power.
That may cause an electric shock, short-circuiting or failure. Make sure disconnect from the
AC mains or shut down the AC mains before accessing to those parts.

Do not connect the cables to the power supply box with its connector or
jack being wet.
That may cause an electric shock, short-circuiting or failure.
■
Do not wet the power supply box or handle it with wet hands.
That may cause an electric shock, short-circuiting or failure.
