For safe operation
Below is very important information about how to safely operate the equipment.
Before operation, be sure to read and fully understand the contents.
WARNING
Be careful about
lifting
Danger of cargo collapse
Be careful to install vacuum pump using
motor handle (DIS-90 mass 14kgs) while
paying attention to stability of suspended
load.
If not, it can cause damage, failure or
bodily injury from falling cargo due to
hoisting failure, or by being caught
between suspended cargo and other
material.
Avoid moisture
Danger of electric shock
Install in an area which is not exposed to
moisture such as rain or steam.
If moisture comes into and tact with the
electric source connection, it can cause
fire or bodily injury due to short-circuit or
electric shock.
Install at a safe
site
Danger of explosion, fire and
accident
Install in an area free from explosive,
flammable or corrosive substances.
If not, it can cause explosion, fire or
accident.
Ask qualified
electrician
Danger of short-circuit and
electric shock
Ask a qualified electrician to perform
electric wiring.
If not, short-circuit or electric shock can
cause fire or bodily injury.
Turn off electric
source
Danger of electric shock and
entanglement
Be sure to turn off electric source on
building site before wiring.
If not, it can cause electric shock or bodily
injury due to turning objects.
Install
overcurrent
protective device
Danger of accident, fire and failure
Be sure to install protective device to
protect circuitry. We recommend
overcurrent protective device (rated 15A)
to protect branch circuit.
If equipment is not stopped in an
emergency, it can cause accident, fire or
failure.
Install
emergency stop
switch
Danger of accident, fire or failure
Be sure to install an electric source
emergency stop switch (or protective
device that can urgently stop).
If equipment is not stopped in an
emergency, it can cause accident, fire or
failure.
Install short
circuit protective
device
Danger of fire and electric shock
Install short circuit protective device.
If not, it can cause bodily injury due to fire
or electric shock.
Install motor
protective circuit
breaker to
protect motor
Danger of electric fire and electric
shock
Install motor protective circuit breaker to
protect motor.
If not, bodily injury due to electric fire or
electric shock can result.
If you have any questions about the
selection of protective devices, contact
either our sales branches who sold it to

Be careful about
wiring
Danger of short-circuit and
electric shock
We recommend an electric source cable
of more than 2mm
2
(more than rated 10A)
cross section area for electric source
cable and earth cord.
Be careful to avoid voltage drop
considering local situation.
If not, it can cause a short-circuit fire and
may result in bodily injury from electric
shock.
Use crimp-style
terminal
Danger of short-circuit and
electric shock
Fit firmly proper round type crimp-style
terminal to electric source cable using
crimp tool and connect to motor terminal
section.
If not, it can cause short-circuit fire or
bodily injury from electric shock due to
looseness or disconnection.
Protect cable
from being
pulled
Danger of short-circuit and
electric shock
Be sure to fit cable-gland to hole of
φ22mm at motor terminal box.
If not, it can cause short-circuit fire or
bodily injury from electric shock.
