1.3.1 Transport, storage
WARNING
Fall hazard
Incorrect handling during transport may result in the motor falling down or swivelling uncontrolledly, and thus
possibly causing serious or fatal injuries such as bruises, contusions and other physical injuries. It may also
result in serious damage to the motor and its environment.
That is why:
– Use the existing threads for ring bolts during transport (see following illustration).
– Do not attach additional loads! The lifting eyes are designed for the motor weight only.
– For transporting the machine units (e.g. gear unit attachments), only use the lifting eyes and pins
provided for this purpose!
– Machine units must not be lifted by attaching them to the individual machines!
To avoid any damage to the motor, the motor must always be lifted via suitable lifting equipment. If the
period between delivery and motor commissioning is more than four years under favourable conditions
(storage in dry and dust-free spaces protected from vibrations), the roller bearings should be replaced.
Unfavourable conditions significantly reduce the period. If necessary, unprotected and finished surfaces
(flange surface, shaft end, ...) may be treated with corrosion protection agents. If necessary, the
winding’s insulation resistance must be checked (

1.3.9 "Checking the insulation resistance").
Changes compared to normal operation (increased power consumption, higher temperatures or
vibrations, unusual noises or odours, response of monitoring systems, etc.) may indicate that the
function is impaired. To avoid personal injury or material damage, the maintenance staff responsible
must be informed of these changes without delay.
In case of doubt, switch off the motor immediately as soon as this is allowed by the system’s state.
Mounting of ring bolts for transport
The number, position and thread size of the ring bolts provided for transport varies depending on the
motor size.

1.3.2 Installation
• After installation, screwed-on lifting lugs must be tightened or removed.
