Grease caps must be available at the shaft outlet and at the terminal box cover. Do not rotate
the motor shaft before commissioning as the protective grease coating will be destroyed. If
rotating parts have to be turned, then apply a new protective coating of grease.
4.10.7 Storage at low temperatures
If machines are stored at temperatures of down to -50° C, then also take into account the
following:
● The normal roller bearing grease of machines is suitable for operating temperatures of
between -30 °C and +130° C. Temperatures down to ‑50° C are harmless for the roller
bearing grease if the machine is non operational or is in storage.
For operation at -50 °C, the bearings have a special grease, e.g. Shell Aero Grease 7.
● Machines with regreasing system must be regreased when commissioning. Double the
amount of grease that is specified on the lubricant plate.
4.10.8 Storing motors together with the driven machine
● Before mounting the motors, grease the free parts of the shaft extension, as well as all
other bare metal parts, such as mounting foot surfaces, flange surfaces, terminal box and
cover contact surfaces. Attach caps filled with roller bearing grease to the shaft output gland
to provide protection against dust and humidity.
● Fill the terminal boxes of the machines with a substance that will absorb moisture, e.g.
Branogel.
● Store the machines in a dry, dust-free room where the temperature is controlled.
4.10.9 Storage outdoors
If the machine is stored outdoors, then the following should additionally be observed:
● Provide protective cover against the effects of sun and rain. Air must freely circulate to
avoid condensation forming.
● Every two months check the following:
– Free parts of the shaft extension and other bare metal parts, e.g. mounting foot surfaces
or the flange faces, terminal box and cover contact surfaces must be greased.
– Caps filled with grease attached to the shaft output gland to provide protection against
the ingress of dust and moisture are still effective.
