Labelling as per ATEX (DIN EN 13463-1):
1. Group (always II, not for mines)
2. Category (2G, 3G for gas or 2D, 3D for dust)
3. Ignition protection type if fitted (c)
4. Explosion group if applicable (IIC, IIB)
5. Temperature class (T1-T3 or T4 for gas) or max. surface
temperature e.g. 125°C for dust)
6. Temperature measurement on commissioning (X)
Section 4.3
S - Number of the special documentation, consisting of serial no. / year
*The maximum permissible speeds are 10% above the rated speed, if the maximum permissible drive power
P1 is not exceeded.
If the fields FR1, FR2, FA1 und FA2 are empty, the forces are zero. If the field xR2 is empty, the point of
application of force FR2 is central on the drive shaft journal (See Figure 3-4).
It should be noted that with geared motors, the electric motor has its own rating plate with a
separate ATEX labelling. The motor labelling must also comply with data for the planning of the
plant or the machine. The lowest explosion protection of the gear unit and the motor
Danger!
It must be checked and ensured that the gear unit type, all technical data and the ATEX
labelling conform to the planning of the plant or the machine.
