Noise emission

Refer to the table “Technical data” for the permissible noise leveling 

free field conditions according to EN ISO 2151.

CAUTION

The sound level of the vacuum pump within a certain perimeter of

the pump is high.

Risk of hearing damage.

Users who are spending a longer period of time in the vicinity of a

non-insulated vacuum pump must wear suitable ear protection.

Safety area

Before any maintenance action, ensure a safety perimeter of a least

610 [mm] around the pump.

Electrical safety

Types of Electrical Work

The following are the four types of electrical work defined by the 

SEMI S2, latest version, guideline:

Type 1

Equipment is fully deenergized.

Type 2

Equipment is energized. Energized circuits are covered or insulated.

NOTE

: Type 2 work includes tasks where the energized circuits are or 

can be measured by placing probes through suitable openings in the 

covers or insulators.

Type 3

Equipment is energized. Energized circuits are exposed and inadvertent 

contact with uninsulated energized parts is possible. Potential exposure

s are no greater than 30 volts rms, 42.4 volts peak, 60 volts dc or 240 

volt-amp in dry locations.

Type 4

Equipment is energized. Energized circuits are exposed and inadvertent 

contact with uninsulated energized parts is possible. Potential

exposures are greater than 30 volts rms, 42.4 volts peak, 60 volts dc, or 

240 volt-amp in dry locations. Potential exposures to

radio-frequency currents, whether induced or via contact, exceed the 

limits in Table A5-1 of Appendix 5 (SEMI S2 guideline).

Lock Out/ Tag Out procedure (Type 1 of

electrical work)

Stop the pump with the LCD controller (press on STOP button

during 10s)

Press on emergency stop button

Switch off the main circuit breaker

Switch off the customer’s power supply

Switch off the water and nitrogen quick connections (inlet first,

then outlet)

Put the label or warning board “Maintenance processing” on or

next to the pump

Emergency off circuit description

The Emergency off circuit may be opened by pressing on emerge

ncy stop button. If this element occurs, then the DP and MB

pumps will immediately stop. The PLC will remain energized to

save the pump status.

If the emergency stop button was pressed, check the start up of

the pump then release this button to restart the pump. Press on

Start button on the LCD controller, the pump will restart.

Installation of the vacuum pump in a

seismic zone

Upon receipt, the vacuum pump is fixed on the transport pallet with

two brackets.

Convey the pump to its final location with a pallet truck before

removing it from its support

Unscrew the fixing screws of the pump on the transport pallet and 

remove the machine from its support with an appropriate lifting

system by using the lifting brackets made for this purpose

The pump must not lay only on the brackets. Unscrew the four

adjusting nuts until the machine legs touch the ground

Check that the wheels no longer touch the ground

CAUTION

The vacuum pump is fixed to the ground with four M10 screws, two

screws per bracket. The fixing screw must stand a 1200 N tensile force 

(per bracket).

The final user must adapt the type of screws depending on the 

ground material.
