1 MACHINE SPECIFICATIONS
Please refer to the cover sheet for our address.
For the area of validity of these operating and assembly in-
structions, please refer to the Declaration of Installation Con-
formity contained in Annex II 1 B.
The technical specifi cations on page 21 ff. apply to the stand-
ard version. Your blower's specifi cations may differ from these
specifi cations (refer to nameplate). If this is the case, please
refer to the enclosed, additionally applicable documents or
your own applicable Operating and Assembly Instructions.
Nameplate
For connection, maintenance and ordering of spare parts,
only the data on the blower nameplate is defi nitive. Also refer
to the nameplate for the serial number of the appliance and
its year of manufacture. Electrical data is provided on the
motor nameplate. The blower nameplate applies to the com-
plete blower. The motor nameplate is subordinate to this.

1.1 Designated use
The operation of an explosion-protected Elektror blower, in
accordance with the 94/9/EC directive, is only permitted in
countries or in economic sectors where this directive is valid
or is not restricted, as well as legally recognised.
Conversion and modifi cations to operational blowers are im-
permissible.
The units described in these operating and assembly instruc-
tions correspond to the category, type of ignition protection,
temperature class, etc. specifi ed on the nameplate.
The following section lists the unit categories according to
ATEX:
Category 3G
The equipment is so designed and constructed as to
prevent ignition sources during normal operation in areas
where an explosion hazard due to gases (G) exists.
Category 3D
The equipment is so designed and constructed as to
prevent ignition sources during normal operation in areas
where an explosion hazard due to dust (D) exists.
Category 2G
The equipment is so designed and constructed as to pre-
vent ignition sources even in the event of disturbances in
areas where an explosion hazard due to gases (G) exists.
Category 2D
The equipment is so designed and constructed as to prevent
ignition sources even in the event of disturbances in areas
where an explosion hazard due to dust (D) exists.
Units according to category 1G or 1D (for Zone 0, Zone 20)
are not included in the scope of supply of Elektror airsystems
gmbh.
As indicated on the nameplates, the units may be suit-
able for use in one of the following areas with potentially
explosive atmospheres (for an exact defi nition refer to:
EN 1127-1):
Zone 2 / 22
Areas in which an explosive atmosphere consisting of a mix-
ture with air of fl ammable substances in the form of gas, va-
pour, mist or dust is not likely to occur in normal operation
but, If it does rarely occur, then it will persist for a short period
only.
Zone 1 / 21
Areas in which an explosive atmosphere consisting of a
mixture with air of fl ammable substances in the form of gas,
vapour, mist or dust is likely to occur in normal operation oc-
casionally.
Explosion group II
Electrical equipment intended for areas not endangered by
fi redamp (other than mining).
Installation type B or C
Blower connected on one end only, that is on pressure end or
intake end (compare DIN 24163).
The same potentially explosive atmosphere is present inside
and outside the blower.
Installation type D
Blower connected on intake and pressure end. For unsealed
Elektror units and equipment, this application is limited to
cases in which the same potentially explosive atmosphere is
present inside and outside the blower.
Ignition sub-group IIA and IIB (cf DIN EN 50014).
Temperature classes:
Units according to Directive 94/9/EC are classifi ed into class-
es of max. permissible surface temperatures (temperature
classes). Information regarding the temperature class is on
the nameplates of the units. The highest permissible surface
temperature class indicated is applicable only if the product
is used for its designated purpose.
Blower section and motor may have individual nameplates.
The lowest category and temperature class indicated for any
component is also applicable for the entire unit.
