Attaching The Rotor Locking Device Prior To Storage - Siemens SIMOTICS M-1PH8 Operating Instructions & Installation Instructions

Protection against humidity
● If a dry storage area is not available, then take the following precautions:
Explosion hazard during commissioning
Storing the machine at temperatures that do not fall within the specified limits can damage
the material of the seals and cause them to fail. There is also a risk that potentially explosive
gaseous atmosphere may enter the machine and ignite during commissioning. Explosions
can occur.
Death, serious injury, or material damage can result.
The materials used are specially designed for the temperature range required by the
customer. Do not store the motor in conditions that lie outside the specified temperature limits.
The relevant temperature limits are specified on the rating plate.

Attaching the rotor locking device prior to storage

Fit the rotor locking device before packing and/or putting it into storage.
If the rotor locking device is not attached on a motor in storage, make sure that you turn the
rotor through 360° regularly to prevent the occurrence of damage as a result of standstill.
CAUTION
Bearing damage caused by vibrations
If storage conditions are inappropriate there is a risk of bearing seizure damage. This can
result in material damage, such as damage to bearings due to vibration.
On machines that have been supplied with a rotor shipping brace, secure the rotor as per
the notes on transportation. Protect the machine against strong radial vibrations, since the
rotor shipping brace might not absorb these completely.

– Include several bags of desiccant in the seal-tight packaging. Check the desiccant and
replace as required.
– Place a humidity meter in the seal-tight packaging to indicate the level of air humidity
inside it.
– Inspect the motor regularly.
