Preparations for use
4.9 Transport and storage
4.9.8
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
● Every two months check the following:

Commissioning after storage
4.9.9.1
Insulation resistance and polarization index
Measuring the insulation resistance and polarization index (PI) provides information on the
condition of the machine. It is therefore important to check the insulation resistance and the
polarization index at the following times:
● Before starting up a machine for the first time
● After an extended period in storage or downtime
● Within the scope of maintenance work
The following information is provided regarding the state of the winding insulation:
● Is the winding head insulation conductively contaminated?
● Has the winding insulation absorbed moisture?
As such, you can determine whether the machine needs commissioning or any necessary
measures such as cleaning and/or drying the winding:
● Can the machine be put into operation?
● Must the windings be cleaned or dried?
Detailed information on testing and the limit values can be found here:
"Testing the insulation resistance and polarization index" (Page 63)
4.9.9.2
Lubricating the roller bearings
If you correctly store the machine for a longer period of time, it can be assumed that within a
period of two years, the grease in the bearings will not deteriorate.
● For motors with thermal class 155, for normal ambient temperatures, use a lithium-soap
● For machines with thermal class 180, and for certain special machines, use the special
34
avoid condensation forming.
– 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.
