Prefitting the Vacuum Pump
Before the pump can be fitted, it needs to be prepared. This preparation work covers the following tasks:
▪ "3.3.2.1 Closing the Opening Mechanism" [ ➙ 92]
▪ "3.3.2.2 Connecting the Power cable" [ ➙ 93]
▪ "3.3.2.4 Fitting and Positioning the Filter" [ ➙ 95]
▪ "3.3.2.5 Preparing and Connecting the Distributor Block" [ ➙ 97]
▪ "3.3.2.7 Placing the Vacuum Pump onto the Slide" [ ➙ 98]

CAUTION
Lifting the vacuum pump
► When lifting the vacuum pump, always take hold of its base. As its center of gravity is above
this base, parts of the pump could be pulled off if you take hold of it elsewhere.
► Never lift the vacuum pump by its front plate! The front plate of the vacuum pump is only
fixed with rubber buffers. Take care not to damage the rubber buffers.

2. Vacuum valve [03109300-xx]
3. Opening mechanism
4. Eyelet
5. Front plate
► You may need to replace the eyelet with ISO4762-
M10x25-A2-70 [03042599-xx]
1. Sealing plugs
2. Sealing ring
3. Opening mechanism
► If not prefitted, position the sealing ring (2) on the
sealing screw (R3/4 St+NBR) [03004775-xx] (1) and
screw both into the opening on the top of the pump
(3).
If there is no sealing ring available, first apply Loctite
55 onto the threaded connection as a sealant.

1. 4 screws on the cover
2. Tension relief
► Remove the four screws (1) fastening the cover on
the electricity connection box and then remove the
cover.
► Turn the strain relief out (2).

3.3.2.3 Adjusting the Supply Voltage of the Vacuum Pump (From Machine No. N001)
Adjusting the Supply Voltage of the Vacuum Pump (From Machine No. N001)
► Depending on the input voltage to the power supply, adjust the vacuum pump to the same input volt-
age and power supply. Connector X96 supplies the vacuum pump with the three phases L1, L2, and
L3 required; for that reason, the relevant country-specific input voltage is applied (see also the doc-
umentation of the rotary field [03125519-xx]). The corresponding label is located on the power supply
unit at connector X101.
► When installing the vacuum pump, make sure that the 110V transformer option is installed and that
the input voltage is 110V.
► Connector X96 is supplied by the 110V transformer (US option). For this reason, set the input voltage
of the vacuum pump to this value.
► Disconnect the vacuum pump power cable [03079997-xx].
▪ Conductor (1) to connection U1
▪ Conductor (2) to connection V1
▪ Conductor (3) to connection W1
► Do not disconnect the protective conductor and the temperature monitoring.
► Fit the cable connections to the pump connections as
follows:
⇨ Conductor (1) to connection U1
⇨ Conductor (2) to connection V1
⇨ Conductor (3) to connection W1
⇨ Protective ground 4 – to connection 4
⇨ The two black cables (temperature monitor) are
connected to a luster terminal (5).
► Remove the nuts from the connections U1, V1, W1
and the protective ground connection (4).
CAUTION!
Make sure that none of the nuts or washers fall inside the
pump.
► Place a washer onto each connection. Position the
corresponding cable shoe onto each connection.
Place another washer onto each cable shoe.
► Hand-tighten the nuts.
NOTICE
Machines with serial nos.: Kxxx/Lxxx/Mxxx
On machines with serial numbers Kxxx/Lxxx/Mxxx, the vacuum pump must be operated in a
delta connection. The power supply transformer of the machine supplies the voltage.
From serial number N001, the vacuum pump is connected directly to the supply mains at the
customer's site via the main switch of the machine.
