Before connecting the power, take heed of the following warnings and
cautions. Failure to do so may result in electric shock or equipment
damage.
WARNING
 Power supply
Be sure to turn on the power to the equipment after confirming
that the power-supply voltage of the equipment matches the
voltage of the power supply
 Power cable and plug
To prevent electric shock and fire, use the power cable supplied
by Yokogawa. For the main power plug, only use a power socket
with a protective grounding terminal. Use of an extension cable
without protective grounding wire will disable the protective
operations
 Protective grounding
To prevent electric shock, be sure to provide protective grounding
before turning on the power to the equipment. The power cable
supplied with this equipment is a 3-pin type with a grounding wire.
Accordingly, use a 3-pin power socket with a protective grounding
terminal. If a 3-pin to 2-pin conversion adapter (usable only in
Japan) is used, securely connect the grounding wire of the
conversion adapter to the protective grounding terminal.
 Need for protective grounding
Do not cut the protective grounding wire running inside or outside
this equipment or remove the connected wires from the protective
grounding terminals. Doing so will put this equipment in a
dangerous condition.
 Defects in protective functions
If any of the protective functions such as protective grounding or
any fuse is suspected as faulty, do not operate this equipment.
Also check the protective functions to ensure absence of defects
before operating this equipment
 Use in gas
Do not operate this equipment in a location where it may come in
contact with flammable or explosive gases or vapors. Using this
equipment in such environment is very dangerous
