PM10U

EBARA

CORPORATION

WARNING

· Carry out the electrical wireing only by qualified electricians.

Connect the grounding wire.

Do not use the power cable adapter.

Granding at the power outlet should be checked by qualified.

Install ELB (or CB) based on the law and the standard in the installation region. ELB (or

CB) is not installed in the pump unit.

Connect the pump to the power supply using the appropriate circuit breaker

(lockout/tagout CB).

Avoid contact and keep inflammable substances out of reach. The inlet and exhaust piping

will remain at a high temperature during operation and for a short time after the pump has

stopped.

Do not use explosive, flammable, toxic or corrosive substances. This pump is suitable for

use on clean and non-corrosive gases.

Check for leaks after you have installed the pump.

Avoid contact and keep inflammable substances out of reach. Do not remove the outer

cover during operation. The pump unit and the inlet piping and exhaust piping will remain

at a high temperature during operation and for a short time after the pump has stopped.

Do not perform a withstand voltage test. Failure to comply could result in damage to the

sensitive devices.

Keep the power supply to the pump turned off until you have finished the wiring, installing

and maintenance work. Also remove the power connector and interrupt the Circuit

Protector (CP) during this.

Do not insert any part of body to ventilation outlet. Moving parts of the cooling fan can

crash and cut.

Do not alter the pump member nor change any parts without the EBARA’s consent or

approval.

PM10U

EBARA

CORPORATION

CAUTION

Be careful not to overturn the pump when pushing and pulling it sideways, because the

width of the pump is small to its height.

Do not step on the pump or place objects on it.

The exhaust piping made by polyvinyl chloride causes the noise thrugh the pipe.

Do not apply the power supply from the pump's power pack to any other equipment as this

will result in malfunctioning of the control units and in pump failure.

Use the correct wiring materials and size to match the operating conditions in accordance

with the power consumption rating and ambient air temperature of the pump.

Vents at both ends of the pump. Place the pump at least 100mm from the stationary

section. If the cooling air supply is insufficient, the pump temperature will rise and problems

such as rotor contact will occur.

Install pump in a location at an ambient not exceeding 30°C. Particular caution is required

when the pump is operated in an enclosed room.

Check the pump according to “8. Troubleshooting” before stopping suddenly. This pump

doesn’t stop by signal “WARNING”. But signal “ALARM” or serious trouble occurs in a

pump when pump driving is continued.

Note

· Placed the pump in an upright position. Do not stack as packing. When the pump is

overturned, this will result in accident.

· A gap of at least 50mm should be left open for ventilation between the pump cover and

the adjacent equipment.

· To fix the pump, the rubber feet of five each are attaches. If the pump is not stable, vibration

and noise of the pump may be increased.

· Do not wire vacant pins.

· Apply a voltage between 4VDC and 27VDC on the equipment side. Do not apply 5VDC

power on the equipment side. The output signals are generated from an open collector

and the pump provides 5VDC power for input signals.

· The output signals are generated from an open collector.

· Wire all signals with the correct polarity (SIG./COM.).

· When output signals energize an inductive load such as a relay, insert a diode (100V. 1A

class) to limit the back electromotive force during de-energization.

· The pump cannot start while the measuring instruments are warming up after the CP is

placed in the ON position.

· Do not start the pump when a WARNING/ALARM has been generated. After you have

taken the remedial actions, reset the pump.
