Power Cable Selection Standards

Thank you very much for your purchasing our vacuum pump.

This vacuum pump does not have any power cable attached as supplied.

It is up to the user to provide an appropriate power cable for your vacuum pump.

Please be advised of the standards and precautions that you should use to provide

the power cable.

1. Power Cable Selection Standards

The pump is equipped with a single-phase 100-120 V (50/60 Hz) and 200-240 V (50/60 Hz) motor.

Power cable selection standards vary with the working power supply voltage, 100-120V or 200-240V.

The power cable selection standards are shown in a table below.

Do not fail to select your power cable in accordance with the standards.

For a shape of the cable plug to be inserted in the pump motor power inlet, select Type IEC60320-C13.

2. Precautions

2.1 Unplug-preventive hardware

Whenever you may operate the vacuum pump with your power cable, provide it with the

unplug-preventive hardware, which should be selected so as to fit the shape of the power cable.

The unplug-preventive hardware allows you to secure the power cable so that the motor may not

Accidentally have it unplugged.

For a procedure for installing the unplug-preventive hardware, refer to “2.2 How to Install

Unplug-preventive Hardware.”

Whenever you may operate the vacuum pump with the power cable, do not fail to secure

it with the unplug-preventive hardware.

Should you operate the vacuum pump without the unplug-preventive hardware, there

is a fear that the power cable may be unplugged during the operation. If so, the

vacuum pump will stop operating, bringing about possibilities, such as electric

shock, injury, fire or the like.

Warning

(2/2)

2.2 How to Install Unplug-preventive Hardware

Install the unplug-preventive hardware in accordance with the procedure as follows:

(1) Let one end of the unplug-preventive hardware

catch the hole to the side of the inlet in the interior.

(2) While pushing the unplug-preventive hardware at

the other end, let it catch the hole to the side of the

inlet in the interior.

(3) Raise the unplug-preventive hardware.

(4) Insert the power cable firmly enough.

(5) Lower the unplug-preventive hardware and

secure the power cable.

Now, the unplug-preventive hardware is completely installed.

0. Introduction

0.1 Before using the vacuum pump

Thank you for purchasing our vacuum pump (hereinafter called “pump”). When you have received

the pump, check that the delivered pump is as per your order and that it has not been damaged in

transportation, etc.

In order to use the pump for as long as possible, read this instruction manual

thoroughly before performing installation, operation, inspection and

maintenance, and sufficiently understand the cautions for safety, the

specifications and operation methods of the pump.

No part of this instruction manual may be copied for use by a third party

without our permission.

0.3 Cautions for safety

This pump is for dry air or the dry nitrogen suck only.

Never allow people other than repair engineers to disassemble or repair the

pump. Failure to do so may result in ignition or malfunction, leading to injury

or electric shock.

Connect the earth wire correctly. It is recommended that a dedicated earth

leakage breaker should be installed. If the earth wire is not connected, there

is a possibility of electric shock occurring in the case of a malfunction

or electrical leakage.

There is a risk of explosion. Never block the outlet or operate the pump with

equipment mounted at the outlet side which blocks the passage of gas.

Otherwise, the internal pump pressure increases causing the pump to explode,

the oil level gauge to protrude or the motor to be overloaded.

This pump is not resistant to pressure. The internal pump pressure is limited

to 0.03 MPa (gauge pressure).

The Vacuum Pump Unit is device a built-in device. Do not install it without

adequate protection against heat hazard. The surface temperature of the

vacuum Pump Unit can exceed 90 degrees in case it is operated under high

pressure (atmospheric to 10kPa).

It gets an electric shock touching the motor energizing part. Please work

after pulling out the power plug without fail when wires electricity is

connected, it checks, and it transfers it.

Danger

Warning

- 04 -

Do not use the pump in an explosive atmosphere. Failure to do so will result

in injury or fire.

When shipping from the factory, the motor is set for 100-120V class. Do not

operate with 200-240V power supply voltage. In order to operate with 200-240V

class, the changeover switch in the terminal box must be changed into 200-240V

class as shown in fig.3.4“Changing the voltage class.”

Never touch the rotating section of the motor, shaft or coupling while the

pump is in operation. Failure to do so will result in injury.

Never place combustible materials around the motor or pump. There is a risk

of fire.

Also, do not place objects which block ventilation around the motor. Abnormal

heat generation may result in burns or fire.

Do not touch the motor while the pump is in operation or when the pump is

still hot immediately after it stops. Touching it will result in burns.

Arrange wires correctly in accordance with the “Electrical Equipment

Technical Standard” and “Wiring Regulations.” Incorrect wiring may result

in fire.

Warning

Caution

Warning

- 05 -

If the pump ceases operation or malfunctions, turn off the power switch

immediately to prevent accidents, and ask the company from which you purchased

the pump or the manufacturer for inspection and repair.

Do not operate the pump without adding pump oil. If it is operated in an

oil-less condition, the pump will be damaged.

② Height above sea level during storage and installation: 1,000 m or less

③ Minimum required distances from the wall, 100mm

④ Other conditions for storage and operation

a) Free from corrosive and explosive gases

b) No condensation

c) Dust-free environment

d) Indoors

e) Do not place pumps on top of each other or place a pump on its side.

f) Not subject to direct sunlight

g) Far from heat sources

h) When you keep it for a long period of time, put pump oil into a pump and seal a inlet

port with a cap.

i) Don't keep it, where moisture is attracted.

Since the pump over 20 kg, do not lift or transport it by yourself. Doing

so may cause an injury. Wear safety shoes at the time of work. Perform such

work by two people as shown in 3.1 “Installation.” and wear safety shoes.
