Please note that for geared motors (gear units with attached electric motors) the electric motor
has its own name plate and separate ATEX designation. 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 labelling applies for the geared motor unit. If the electric motor is driven
with a frequency inverter, the motor requires ATEX approval for inverter operation.
3.5 Checking the configuration
3.6 Transporting the gear unit
Attention!
Avoid damage to the gear unit. Impacts to the free ends of the shafts may cause
internal damage to the gear unit.
Use adequately dimensioned and suitable means of transportation. Lifting tackle must
be designed for the weight of the gear unit. The weight of the gear unit can be obtained
from the dispatch documents.
The gear unit should remain on the transport packaging during transportation. It must be
transported without oil. Only the four ring bolts (1) (See Figure 3-2) provided may be used for
transporting the gear unit. For additional drive units and components, an additional lifting point
may be necessary. The ends of the shafts must not be used for transportation, as this may
seriously damage the gear unit. The ring bolts screwed into the gear unit must be used for
transportation. If geared motors have an additional eyebolt attached to the motor, this must not
be used. When lifting with the ring bolts, there must be no oblique force.
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.
Danger!
The gear unit may only be operated in the stated configuration. The permissible
configuration is stated on the name plate (IM…). If an X is present in the field IM, the
special documentation, whose number is in field S, must be observed. Section 6.1, or
the special documentation, shows the configuration of the individual types of gear
units. It must be checked and ensured that the configuration as stated on the name
plate complies with the installation orientation and that the installation orientation does
not change during operation.
Danger!
To prevent injury, the danger area must be generously cordoned off. Standing under
the gear unit during transport is extremely dangerous.
