Danger of electric fire and electric shock (refer to chart 1 on page 15)
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 the
dealer who sold it to you or us.

Danger of short-circuit and electric shock
We recommend an electric source cable of more than 2mm
2
(more than rated
10A/1phase, 7A/3phase for ISP-250C and more than rated 18A/1phase,
15A/3phase for ISP-500C) cross section area for electric source cable and ground
cable.
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.

Danger of electric shock
Connect ground cable to ground terminal in motor terminal box.
If not, it can cause bodily injury from electric shock.
Be sure to ground
Danger of restart
Be sure to switch off electric source before maintenance or inspection.
Single-phase motor has a thermal protector.

When you used this pump in Europe.
This vacuum pump must be equipped with a main disconnect device in accordance with requirements of
EN60204-1, clause 5.3.2.
It is recommended to use a circuit breaker as main breaker which is suitable for
isolation according to EN60947-2 and is equipped with an operating handle which is lockable in OFF position
and complies with the other requirements of EN60204-1, clause 5.3.
CAUTION
Motor burnout
Before doing any wiring, check electric source and voltage.
Single-phase is a multi voltage type of AC100V/AC200V. Three-phase is a multi
voltage type of AC200V/AC400V.
Voltage can be changed at terminal block.
This pump is wired to 200V when delivered to you.
Check your electric source, voltage, and wire correctly to terminal block.
Improper wiring and incorrect voltage can cause motor burnout.
Check voltage
