Risk of corrosion due to condensation
If the machine and/or ambient temperatures fluctuate, this can result in condensation inside
the machine.
• If available, remove the drain plugs or drain screws to drain the water depending on the
ambient and operating conditions.
• If available, re-attach the drain plugs or drain screws.
If the motor is equipped with drain plugs, then the water can drain away by itself.
Switching on the machine with anti-condensation heating (optional)
Minor injury or material damage can occur if you do not observe the following:
• If available, switch off the anti-condensation heating each time before switching on.

Explosion hazard from hybrid mixtures
Hybrid mixtures are mixtures of flammable dusts with explosive gas/air atmospheres which
can together create a dangerous explosive atmosphere if they occur at the same time.
Changes can arise in the safety characteristics here, such as a change in the zonal
classification, increase in the explosion pressure, reduction in the minimum ignition energy
and a reduction in the maximum temperatures to be observed.
An explosion can result. This can result in death, serious injury or material damage.
● For this reason, the relative characteristics must be considered both for gas (zones 0, 1
and 2) and for dust (zones 20, 21 and 22) where hybrid mixtures arise. It is necessary for
a competent assessor to determine in the individual case whether the parameters
determining ignition are unfavorably affected in a particular hybrid mixture.
● Motors with dual plates for G (“Gas”) and D (“Dust”) may only be used where these two
occur after prior examination of the properties of the hybrid mixtures by the user.
