COBRA DS vacuum pump

Noise emission

Refer to the table “Technical data” for the permissible noise level in 

free field conditions according to EN ISO 2151.

CAUTION

The intensity of the noise of the vacuum pump is higher within a

certain area of the pump.

Risk of hearing damage.

Users must wear ear protection when spending a longer period of

time in the vicinity of a non-insulated vacuum pump.

Maintenance clearance

Before any maintenance action, ensure a maintenance clearance

around the pump of min. 610 [mm].

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 exposu-

res 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 exposu-

res 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 cur-

rents, 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 remote control (press on STOP button

during 10s)

Press on emergency stop button

Switch off the main disconnect switch

Switch off the customer’s power supply

Switch off the water (inlet first, then outlet) and nitrogen quick

connections

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

next to the pump

Safety Lockout procedure

Take off the label or warning board “Maintenance processing”

Check the cooling liquid and oil levels according to the chapters

“Checking the oil level” and “Checking the cooling liquid level”

Close the cover

Switch on the main disconnect switch

Release the emergency stop button

Switch on the water (outlet first, then inlet) and nitrogen quick

connections

Start the pump with the remote control (press on START button)

Emergency off circuit description

The Emergency off circuit may be opened by pressing on emergen

cy stop button. If this element shows, then the pump will immediat

ely 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 remote control, the pump will restart.

Lock out/ Tag out for hydraulics and pneumatics

Hydraulics: cooling water

Pneumatics: nitrogen

Lock Out/ Tag Out procedure (Type 1 of

electrical work)

Stop the pump with the remote control (press on STOP button

during 10s)

Press on emergency stop button

Switch off the main disconnect switch

Switch off the customer’s power supply

Switch off the water (inlet first, then outlet) and nitrogen quick

connections

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

next to the pump

The end user is responsible for providing energy isolation capabilities

on the water and nitrogen

Transport

The COBRA DS vacuum pumps are tested and checked in our factory 

before careful packing. Check the packaging for transport damage

when the goods arrive. The pump can withstand temperatures bet-

ween -25°C and +55°C during transport.

Transport in packed state

Packed on a pallet, the vacuum pump can be moved with a hand

forklift truck.

Transport in unpacked state

The vacuum pump is fastened to the pallet with fixing pins:
