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 24 ff. apply to the
standard 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-
14
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 2014/34/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.
EPL (Equipment Protection Level)
G area at risk of gas explosions

D area at risk of dust explosions

Gb:
Equipment with a high protection level for use in areas at
risk of gas explosions.
There is no ignition risk during normal operation or in the
case of expected faults.
Gc / Dc:
Equipment with an enhanced protection level for use in
areas at risk of gas / dust explosions.
There is no ignition risk during normal operation or in the
case of expected faults due to additional protective meas-
ures.
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
mixture with air of fl ammable substances in the form of gas,
vapour, mist or air mixtures 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
Areas in which an explosive atmosphere consisting of a
mixture with air of fl ammable substances in the form of gas,
vapour or mist is likely to occur in normal operation occasion-
ally.
Equipment group II
Electrical equipment intended for areas not endangered by
fi redamp (other than mining).
Explosion groups
The following ATEX fans are available in the following ex-
plosion groups:
Explosion group Explosion group
