Transport/storage
Inspect the shipment for any damage that may have occurred in transit as soon as you
receive the delivery. Inform the shipping company immediately. It may be necessary to
preclude startup.
Tighten the eyebolts securely. They are designed to carry only the weight of the
motor/gearmotor; do not attach any additional loads.
The built-in lifting eyebolts comply with DIN 580. Always observe the loads and regula-
tions listed in this standard. If the gearmotor is equipped with two eyebolts, then both
should be used for transportation. In this case, the tension force vector of the slings must
not exceed a 45° angle according to DIN 580.
Use suitable, sufficiently rated handling equipment if required. Reattach these in the
case of further transportation.
Store the motor/gearmotor in a dry, dust-free environment if it is not to be installed
straight away. You must not store the motor/gearmotor outdoors or on the fan guard.
The motor/gearmotor can be stored for up to 9 months without requiring any special
measures before startup.
2.7
Installation
Make sure that the supports are even, the foot and flange mounting is correct and if
there is direct coupling, align with precision. Resonances between the rotational fre-
quency and the double network frequency caused by the structure are to be avoided.
Release the brake (if installed), turn rotor manually, check for unusual grinding noise.
Check the direction of rotation in decoupled status.
Only install or remove belt pulleys and couplings using suitable devices (heat up) and
cover with a touch guard. Avoid improper belt tension.
Make the pipe connections that may eventually be required. Mounting positions with
shaft ends pointing upwards should be equipped with a cover to prevent foreign objects
from falling into the fan. Ensure that ventilation openings are not obstructed and that
used air, including air from adjacent units, cannot be drawn in again straight away.
