Safety Information
(1) Meaning of markings
The signal terminology and symbols related to warnings in the instruction manual are defined
below. The alert symbol mark ( : General caution mark) indicates the possibility of hazard or
damage and also means “Refer to the instruction manual.”
:
Indicates the degree of hazard which can lead to death or serious injury if you fail to operate the
product properly.
Serious injury means an injury such as loss of sight, burns (high temperature or low temperature),
electric shock, bone fracture and poisoning, and the aftereffects of the injury remains or the injury
requires hospitalization or long periods of outpatient treatment.
:
Indicates the degree of hazard/loss which can result in injury or property damage if you fail to operate
the product properly.
Injury means an injury not requiring hospitalization or long periods of outpatient treatment and refers
to burns or electric shock. Property damage refers to widespread damage to the home, household
goods and livestock, pets, equipment, materials, etc. (damage to other than the product itself).
【IMPORTANT】Indicates important matters other than and . They are the
matters such as preventing damage to the product main body, preventing data
destruction, preventing wasting time, maintaining performance, and observing
regulations.
〔NOTE〕 Indicates comments, reasons, background information, a case example and other
items to help the reader understand the meaning.
＞＞ Indicates reference items.
①, ②, ③Indicates item numbers such as the ones used in operations.
(2) Safety compliance items

plug and external connection connectors. In addition, do not connect or disconnect
them with wet hands. Water or reagent entering the product may short the circuits
and cause electric shock or fire.
Do not operate the product with wet hands. It may cause electric shock or fire.
The product main body must be grounded. If a problem occurs in the power supply
system, an electric shock may result.
Hazardous substances
When using the liquid chemical pump to clean the electrodes by chemical, procure
the Safety Data Sheet (SDS) for the reagent to be handled from the vendor and
handle the reagents safely in accordance with the description.
Injury
Do not touch the arm section during measurement. During the cleaning operation,
the arm moves and there is the danger of pinching your fingers or getting injured.
Disassembly and Modification
Do not disassemble or modify the sections of the product that are not described in
the instruction manual. The product can be damaged.
Caution Label Lost
If any caution label affixed to this product becomes too difficult to read or lost, please

4.2 Wiring
(1) Power cable and ground connections
Never use a power cable and 3P-2P adapter other than the accessories.
(a)Confirm that the power switch on the left-hand side of the product main body is off (OFF) and
connect the product side plug of the accessory power cable to the power inlet on the back side of
the main body. Connect the plug at the other end of the power cable to an AC power outlet.
Power Cable and Ground Connections
