When using clutches in mining operations (category
M2
) the clutch
protection must be able to withstand higher mechanical loads than
in other areas. Simple damage (such as dents) may not lead to
slipping of the clutch, for which a gap greater than 5 mm to the ro-
tating parts must be selected. Furthermore, the cover must conduct
electricity and also be included in the equipotential bonding. When
using in areas with high risk of dust explosions, dust may not build
up in order to avoid the risk of spontaneous combustion. The
clutches may not run in dust accumulation. The operator must de-
termine corresponding checking and cleaning intervals according
to his own experience. The cover may not have any openings.
The dimensions for these openings can be obtained from the fol-
lowing table:

CAUTION!
Damage to persons from moving
components!
Rotating components can cause injury.
► Only remove the cover when the system is not
running. Risk of injury! If anything is conspicuous
(e.g., vibration and different running noises), the
system must be shut down immediately.
► Eliminate causes. Other components in the sys-
tem could be the cause. e.g., Displacement of
the input or output side.
