SAFETY PRECAUTIONS
The following section describes precautions to prevent personal injury or damage. Hazardous situations, which
can occur due to mishandling of the equipment, are classified by the safety alert symbols shown below.
DANGER WARNING CAUTION
This section indicates an immensely
hazardous situation, which, if not
avoided, will result in death or
serious injury.
This section indicates a potentially
hazardous situation, which, if not
avoided, can result in death or
serious injury.
This section indicates a potentially
human injury or hazardous situation,
which, if not avoided, may result in
obstacles or property damage.
DANGER
Have personnel with specialized knowledge do work.
Do not run the unit with any equipment cover open.
MUST
Transport, installation, piping, wiring, running, operation,
maintenance, and check of the unit must be conducted by persons
who have specialized knowledge about the said work. Be sure to
check applicable power supply (voltage, frequency) and current.
PROHIBIT
Do not run the unit with opening the
casing of equipment or the terminal
cover of the motor or electrical parts.
Doing so will result in an electric shock.
Check to be sure the specifications and then connect power supply wires.
Do not use the unit out of spec.
MUST
Be sure to connect power supply
wires as shown in the wiring diagram
or the operation manual. Faulty wiring
will result in an electric shock or a fire.
MUST
Do not use the unit out of specifications set forth in
catalogs or delivery specifications concerned. Doing
so will result in serious accidents such as damage to
the main machine, injury, a fire, or an electric shock.
Be sure to establish a proper ground.
Check the mass and suspend from a specified position.
CONNECT
GROUND WIRE
The unit has a noise filter.
Connecting no ground wire will
result in an electric shock.
MUST
Check the unit for the mass and then suspend
the unit from a position specified by the outline
drawing, within the range of rated weight of a
the carrier. If not heeded, the unit will drop or
tumble, thus resulting in injury or damage.
Do not touch the unit with hands or body.
Do not use in explosive atmospheres.
PROHIBIT
The casing surface may be quite
hot during operation. Do not touch
the unit directly with your hands or
body to prevent burns.
PROHIBIT
Do not install the unit in places with
potential hazards for the generation,
inflow, accumulation, or leak of flammable
gas, or with suspended carbon fiber.
Otherwise, you may get a burn.
Wait 5 minutes to conduct work after shutting down power.
Do not splash water, or touch with wet hands.
PROHIBIT
Incomplete discharging from
internal high-voltage live parts (e.g.
capacitor) will result in an electric
shock.
PROHIBIT
Do not dip the unit in water or souse water over the unit.
Doing so will result in short circuit or an electric shock.
Also, do not touch the electrical components with
wet hands. Doing so can result in an electric shock.
Turn OFF power and then conduct work.
MUST
Before conduct work, be sure to turn OFF
the power supply. Conducting any live-
wire work will result in an electric shock.
Lock the power supply box (with a key)
not to energize by mistake.
Be sure to observe the precautions shown below.
