Installation
DANGER
Electrical hazard!
The electrical connection must be carried out by
qualified and authorized electricians!
DANGER
Electrical hazard!
Before beginning any work on the system:
• De-energize it.
• Protect it from being switched on again.
• Make sure that it is de-energized.
• Earth it and bypass it.
• Cover or block off adjoining parts which are
still live.
DANGER
Electrical hazard!
Replace any loose connections and burnt and
scorched feed lines!
DANGER
Electrical hazard!
The system is to be installed in such a way that
external effects cannot lead to damage of the
electrical equipment.
Lay out electrical cables free of damage from
external influences and make sure they are not
under tension!
CAUTION
An incorrect electrical connection can severely
damage the system!
Regulations:
Set up the electrical connection:
• in accordance with the currently valid national,
local and plant-specific regulations and re-
quirements,
• in accordance with the regulations of the
power company.
Supply of electrical power:
The conditions at the place of use must agree
with the details on the data plate.
Permissible deviations which do not lead to loss
of performance:
• ±5% variation in voltage
• ±2% deviation in frequency
5.2.1 Connecting mains cable
DANGER
Danger from lethal leakage current
(PE) >3.5 mA to earth!
Set up connection as a permanent installation.
Set up double protective earth system.
Set up the electrical connection:
• as a permanent safe electrical connection.
• as permanent wiring with suitable cable sock-
ets.
• Connect the mains connecting cable (pos.
19,
page
4) in accordance with the following dia-
gram on the operator’s side of electrical cabi-
net:
Conductor Connection
Conductor 1 L1
Conductor 2 L2
Conductor 3 L3
Protective conductor
(green-yellow)
Terminal
• Ground (pos. 18, page 4) the earth connec-
tion.
WARNING
Electrical hazard!
Air gaps between naked, current-carrying parts
and between such parts and to ground:
5.5 mm [0.217"] (at a measured voltage of
U
N
≤ 690V)
Ends of wires must not stick out!
WARNING
Electrical hazard!
Connecting terminals must be free of
• foreign objects,
• dirt,
• moisture.
Close and seal the cable entry openings against
the entry of dust and water.
Check regularly to make sure they are sealed
tight.

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.

Operation
7 Operation
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).
