The device identification indicates the device group and the category.

The device identification is determined as follows:

e.g. CE 0102 II 2 G Ex d IIC T3

– CE The symbol of conformity CE is for ”Communauté Européenne” (European Community”

By means of the CE Marking the manufacturer declares that the product concerned has been manufactured
in compliance with all applicable regulations and requirements of the Directive 94/9/EC and that the product
was subject to the relating conformity assessment procedures.

The indicated grease life or relubrication intervals are applicable for an ambient temperature of max. 40C.
For every 10C temperature rise, the lubrication interval is to be reduced by factor 0.7 of the value shown in the table (max. 20C = factor 0.5).
Twice the grease life can be expected at an ambient temperature of x 25C however, 40 000 h at a maximum.
Intervals for operation of a 60 Hz power supply on request.
In case of pure coupling operation with flexible coupling the calculated useful bearing life L10h is more than 50 000 hours.
Grease life and relubrication intervals must be observed.

The indicated grease life or relubrication intervals are applicable for an ambient temperature of max. 40_C.
For every 10_C temperature rise, the lubrication interval is to be reduced by factor 0.7 of the value shown in the table (max. 20_C = factor 0.5).

Twice the grease life can be expected at an ambient temperature of x 25_C however, 40 000 h at a maximum.
Intervals for operation of a 60 Hz power supply on request.

In case of pure coupling operation with flexible coupling the calculated useful bearing life L10h is more than 50 000 hours.
Grease life and relubrication intervals must be observed.

Motor protection
As additional protection a thermal
motor protection by means of
PTC–thermistors or flow control-

Output
The rated outputs and operating
data given in the tables are valid
for duty type S1 according to
EN 60034–1 at a rated frequency
of 50 Hz and the rated voltage.

Cooling water requirement

The cooling water requirement as
indicated in the tables is based on
an inlet temperature of Te = 20

Single dimension drawings in DXF format

Available dimension drawings

In the entire technical list the dimension drawings are assigned to the respective type series.
The dimension drawings as described herein are available:

Compiled dimension drawings

The numbers of the compiled dimension drawings are indicated for all type series.
With a click on the blue marked number fields the dimension drawings are
indicated as PDF file (Acrobat Reader) and can be printed for information.

Single dimension drawings

Assignment of the single dimension drawings, data sheets and characteristic curves to all standard motors is
made in the output tables on the left margin.
With a click on the yellow fields the dimension drawings are indicated as PDF file (Acrobat Reader).
Three mounting types each (B3 ..., B5 ..., B35 ....) are opened when called and can be leafed through and printed
for information.

The same dimension drawings with the same file name are also available as DXF file to scale for CAD applica-
tions.
In the following tables the dimension drawing numbers are selectable as assigned to the types and the mounting
types.
The files can be called directly from the CAD application on this CD and inserted.
They can be found in the folders:

For the series A..., A..K, E... :

CD Drive /IM01–V03_CD/DXF–Maßbild_Dim–Drawing/A–Mot/ ...

For the series D... :

CD Drive /IM01–V03_CD/DXF–Maßbild_Dim–Drawing/D–Mot/ ...

For the medium–voltage motors:
