3.1 Wiring
WARNING
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.
Ask qualified
electrician
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.
Turn off electric
source
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 overcurrent
protective device
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 emergency
stop switch
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 short circuit
protective device
Danger of electric fire and electric shock (refer to chart 1 on page 14)
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

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.
Be careful about
wiring
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.
Use crimp-style
terminal
Danger of short-circuit and electric shock
Be sure to fit cable-gland to hole of
φ
22mm at motor terminal box.
If not, it can cause short-circuit fire or bodily injury from electric shock.
Protect cable from
being pulled
Danger of short-circuit and electric shock
The power-supply conductor shall be free from strain including twisting by using
cord anchorage, which is specified by the local electrical wiring regulation.
If not, it can cause short-circuit fire or bodily injury from electric shock.
Protect cable from
being pulled
Danger of electric shock
Connect earth cord to earth terminal in motor terminal box.
If not, it can cause bodily injury from electric shock.
Be sure to ground
