Commissioning
5.2.2 Installing the EMERGENCY Stop
switch
• The EMERGENCY stop system must be
guaranteed via an external control unit.
• This control unit must prevent an auto-
matic re-starting of the system
5.2.3 Connecting the earth leakage current
breaker
DANGER
Danger from lethal electric shock!
In the case of a fault to frame a smooth DC
earth fault can block the release of an AC or
pulse current earth fault current breaker and
thus neutralize the protection system for all
components in the earth fault current breaker.
• Use a pulse current earth fault current
breaker in equipment containing driver regu-
lators with single phase mains connection
(L1/N).
• Use an earth fault current breaker suitable for
all types of currents in equipment with driver
regulators with three-phase mains connection
(L1/L2/L3).
• Install earth fault current between mains feed
and the driver regulator only.
• Earth fault current breakers can be acciden-
tally triggered by
-
capacitive equalizing currents from the ca-
ble shield when operating (especially with
long, shielded power cables),
-
connecting several driver regulators to the
mains at the same time,
-
using additional noise filters.
5.2.4 Connecting control line
Connect the control line plug from the equipment
to the control system (pos.
23, page 4).
Monitoring components are controlled in accor-
dance with operating specifications.
5.3 Mechanically connecting the system
CAUTION
When attaching hoses, make sure that these
are free from mechanical stresses.
Gases / vapours are sucked in via the suction
inlet (pos.
5, page 3) and discharged via the ex-
tracted air vent (pos.
9, page 3).
Remove the seal
The connection openings are sealed at delivery
in order to prevent ingress of foreign matter to the
intake connection (pos.
5, page 3).
Remove the seals immediately before connecting
up the hose system.
5.3.1 Connect the suction intake
Connect the suction line on the plant side to the
suction intake (pos.
5, page 3) and secure with
hose clip.
5.3.2 Cooling air vents
• Check cooling air vents (pos. 7, page 3) for
foreign objects and remove them.
The side cooling air vents can be closed while
operating under normal conditions.
5.3.3 Extracted air vent
The gases / vapours are discharged via the ex-
tracted air vent (pos.
9, page 3) into the sur-
roundings.
No assembly steps are needed here.
6 Commissioning
6.1 Preparing and starting up the system
The start-up procedure on commissioning the
system is the same as for operation of the sys-
tem.
6.2 Switching off the system
The procedure for switching off the system on
commissioning it is the same as for operation of
the system.

WARNING
Improper handling of the system can result
in serious or fatal injuries!
Have you read the safety notes in chapter
1
Safety, page 5 f.?
If not then you are not allowed to carry out any
work on or with the system!
WARNING
Improper handling of the system can result
in serious or fatal injuries!
Operate the system
• the purposes given under "
Correct Use Of
The Equipment
", page 7!
• using the media listed under "
Correct Use Of
The Equipment
", page 7!
• at the values given under "
Technical Data",
page
8!
WARNING
Hazard presented by negative pressure!
Hazard presented by moving parts!
• First connect the suction intake.
• Then check the connections and fasteners
have a tight fit and are sealed.
• And only then start up the system!
CAUTION
Risk of burns and scalds.
The system housing heats up to 85ºC under
normal operating conditions, especially around
the extracted air vent (pos.
9, page 3).
• wear gloves.
7.1 Starting up the system
• Switch on the power supply.
• The system begins to suck in the gases / va-
pours.
7.2 Switching off the system
DANGER
Electrical hazard!
The system is still live for a period of at least 3
minutes following disconnection of the power
supply.
• Before carrying out any work on the system
make sure that it is de-energized.
Make sure that the plant's working processes
allow the operation of the system to be inter-
rupted.
The system can be switched off from every oper-
ating condition.
• Switch off the power supply.
• The system interrupts the suction of the gases
/ vapours.
If the system is to be shut down for a longer pe-
riod of time: chapter
8 Decommissioning the ma-
chine and shutting it down for a longer period of
time
, page 14.
7.3 System in normal operation
CAUTION
Risk of burns and scalds.
The system housing heats up to 85ºC under
normal operating conditions, especially around
the extracted air vent (pos.
9, page 3).
• wear gloves.
If the cooling air vent / in-line filter are ex-
tremely dirty, the surface temperature on the
housing can reach over 85ºC!
• Clean cooling air vent / in-line filter (see
page
14).
It is possible to run the system continuously at
maximum vacuum and/or minimum intake pres-
sure (against closed suction slide).

WARNING
Improper handling of the system can result
in serious or fatal injuries!
Have you read the safety notes in chapter
1
Safety, page 5 f.?
If not then you are not allowed to carry out any
work on or with the system!
WARNING
Risks of burns and scalding from hot sur-
faces on the unit.
• Before working on the unit, allow the system
to cool down for at least 30 min after shutting
it down!
When shut down for longer periods
from about 4 weeks) the system can:
•
remain connected to the plant,
•
be disconnected from the plant so that it can
be sent to store.
8.1 Storage conditions
To avoid damage when stored for some time, the
environment must be:
• dry,
• free of dust,
• subject to low oscillations (effective value for
the speed of oscillation v
eff
≤ 0.2 mm/s
[0.008"/sec]).
8.2 Commissioning after a long shutdown
period
Commissioning after a long shutdown period:
• Measuring the motor insulation resistance.
For values ≤ 1kΩ per volt measured voltage
dry the coil.
• For new systems:
-
Install the system (chapter 5, page 9).
• Start up the system (chapter
6, page 12).

Electrical hazard!
Work on electrical equipment may only be car-
ried out by qualified and authorized electricians!
