Installation

5.1 Installing the system

CAUTION

Risk of stumbling and falling!

Make sure that the system does not create po-

tential stumbling points!

If necessary barricade off the system with a

protective fence or mark it out with red-and-

white tape or similar.

CAUTION

Risk of damaging the system through over-

heating!

The system is to be set up so that the discharge

of heat and the inflow of cool air are not hin-

dered. The minimum gap for heat dissipation

(

Fig. 4: Minimum gaps heat dissipation) is to be

maintained.

Outlet air from other machines and equipment

must not be directly sucked into the machine!

WARNING

Risk presented by system falling over or

falling down!

When setting up moveable machine parts or

when installing at a considerable height and

without any safety protection against falling then

the system must be secured to the surface it is

set up on.

Conditions for setting up the system:

Set up the system:

• on even, level surfaces,

• on stationary (fixed) surfaces or structures,

• at a height of a max. 1000 m [3280 ft] above

mean sea level.

When setting up at over 1,000 m [3280 ft]

above sea level, please check with the service

department first.

< 0,09 m

< 0,2 m

When setting up the system the following points

are to be observed:

• The load-bearing capacity of the installation

surface must be designed to take the weight

of the system.

• The oscillatory response at the place of

installation must be taken into consideration.

The overall oscillations in the system depend

on the following factors:

the natural oscillations in the system,

the alignment and positioning,

The nature (oscillatory response) of the

bearing surfaces,

the effects resulting from oscillations in

other components and parts of the plant

(external oscillations).

The maximum permissible value for oscillations is

eff

= 4.5 mm/s [0.177"/s].

To ensure the system functions properly and has

a long service life, this value should not be ex-

ceeded.

As a rule this value can be kept to without the

need for a special type of foundation or a special

base plate.

For other details on the system's oscillatory re-

sponse, check with the service department.

• System using lockable wheels (pos.

11, pa-

3) secure against to stop it rolling away.

5.2 Connecting the system to the electrical

supply

DANGER

Electrical hazard!

Incorrect actions can lead to severe harm to

persons and damage to objects!

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

≤ 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.
