4.7 Operation of the gear unit in explosive areas
Danger!
When operating the gear unit, the instructions in this operating manual must be
complied with.
The prescribed inspection and servicing intervals must be complied with.
It must be ensured that the power ratings stated on the rating plate are not exceeded. If,
e.g. for variable speed drive units, there are several operating points, the maximum
permissible drive power P1 or the maximum permissible torque on the driven shaft M2
or the maximum permissible speed must not be exceeded at any operating point.
Overload of the gear unit must be ruled out.
If the gear unit is equipped with a cooling coil, it may only be put into operation if the
cooling coil has been connected to the cooling circuit and the cooling circuit is in
operation. The temperature of the cooling fluid and the cooling fluid flow rate must be
monitored and ensured by the operator.
Gear units with an integrated back stop on the drive shaft may only be operated at
more than the minimum speed of the gear unit drive shaft, n1min= 900 min
-1
.
During operation, there must be no electrostatic charging effects on the surface of the
gear unit (e.g. friction on the surface of the housing).
During operation, if any of the irregularities described in Section 4.5 are detected, or
the temperature sticker has turned black, the gear unit must be shut down and
Getriebebau NORD must be consulted.
