Vacuum Pumps Mink MM 1402 AV Installation and

In case the length of the discharge line exceeds 2 m it is prudent to use larger line sizes in order to avoid a loss of efficiency and an overload of the vacuum pump. Seek advice from your Busch representative!

l

Make sure that the discharge line either slopes away from the vacuum pump or provide a liquid separator or a drip leg with a drain cock, so that no liquids can back up into the vacuum pump

Electrical Connection / Controls

l

Make sure that the stipulations acc. to the EMC-Directive

2004/108/EC and Low-Voltage-Directive 2006/95/EC as well as the EN-standards, electrical and occupational safety directives and the local or national regulations, respectively, are complied with

(this is the responsibility of the designer of the machinery into which the vacuum pump is to be incorporated;

Ú page 15: note in

the EC-Declaration of Conformity).

l

Make sure that the power supply for the drive motor is compatible with the data on the nameplate of the drive motor l

Make sure that an overload protection according to EN 60204-1 is provided for the drive motor l

Make sure that the drive of the vacuum pump will not be affected by electric or electromagnetic disturbance from the mains; if necessary seek advice from the Busch service

In case of mobile installation:

K

Provide the electrical connection with grommets that serve as strain-relief

Set down or mount the vacuum pump at its location

Checking Synchronising Gear Oil

The vacuum pump is delivered with oil filled synchronising gear.

The level shall be slightly above the middle of the sight glass (j, 76).

l

Check on the sight glass (j, 76) that the proper amount of oil is filled

Connecting Electrically

WARNING

_ab

Risk of electrical shock, risk of damage to equipment.

Electrical installation work must only be executed by qualified personnel that knows and observes the following regulations:

- IEC 364 or CENELEC HD 384 or DIN VDE 0100, respectively,

- IEC-Report 664 or DIN VDE 0110,

- BGV A2 (VBG 4) or corresponding national accident prevention regulation.

CAUTION

_a

The connection schemes given below are typical. Depending on the specific order or for certain markets deviating connection schemes may apply.

Risk of damage to the drive motor!

The inside of the terminal box shall be checked for drive motor connection instructions/schemes.

Note: For the connection of a drive with integrated frequency inverter see the separate operating instructions!
