Screw Compressor Packages
6.4.1 Use in explosive atmospheres,
installation zones 1 und 2
Danger!
The same regulations apply to the
operating instructions for screw com-
pressor packages in potentially explo-
sive atmospheres as described in the
respective applicable operating man-
ual.
In addition to this, the following exten-
sions apply:
1. The relevant electrical engineering
regulations for installations in
potentially explosive atmos-
pheres , especially EN 60079-10,
apply to the installation and con-
nection of electrical components.
Relevant prescribed cabling mate-
rial must be used.
2. The whole screw compressor
package must be earthed by the
owner operator.
6.5 Sound insulation, weather protec-
tion
If the screw compressor package is intended for out-
door installation, it must be provided with a suitable
housing for sound insulation and weather protection
by the customer. The weather protection must pro-
vide the machine with adequate protection against
the climatic conditions at the installation location.
Hint!
The screw compressor package is not
intended for unprotected outdoor
installation. Protection against exter-
nal influences, especially dirt, dust
and moisture (wetness), is essential.

The manufacturer will not accept liability for damage
due to incorrect outdoor installation.
6.6 Information regarding noise emis-
sions
The noise information provides approximate parame-
ters and apply to the installation without any secon-
dary noise protection measures.
The information has a tolerance of ±3 dB.
The precise data depend closely on the emission
values for the motors, which are manufacturer
dependent.
Should local conditions require adherence to noise
levels, a calculation should be made using the spe-
cific motor data in individual cases.
Sound insulation measures, such as motor encapsu-
lation or complete package encapsulation can ach-
ieve a significant reduction in sound level.
Wearing hearing protection with sufficient noise
reduction is recommended in rooms with running
screw compressor packages.
Caution!
According to EU Directive 2003/10/EC,
the allowable exposure limit value
regarding the daily noise exposure
level is 80 db(A). In the event of noise
levels above this limit value the sys-
tem operator must provide the opera-
tor with information on exposure to
noise and personal hearing protection
and ensure that this is also worn
(2003/10/EC Article 6).
