Safety Notes

Transport
Immediately upon receipt, inspect the shipment for any damage that may have occurred
during transportation. Inform the shipping company immediately. It may be necessary to
preclude startup.
Tighten the eyebolts securely. They are only intended for the weight of the motor/gear-
motor; 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 of
these 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 when necessary. Remove any trans-
portation fixtures prior to startup. Reattach these in the case of further transportation.
When storing low voltage machines, make sure to keep it in a dry, dust-free environment
with minimum vibration (v
eff
≤
0.2 mm/s) (damage to stalled bearings). Measure the in-
sulation resistance prior to startup. Dry the winding if values
≤
1 k
Ω
per volt of the rated
voltage.

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.
Turn the rotor manually and listen for unusual noises. 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.
Observe the notes in section "Mechanical Installation" (see page 14)!
