5.2.7 Putting the machine down
Requirements
The following preconditions must be satisfied before setting down the machine at the
installation location:
● The mating faces must be clean.
● The anti-corrosion protection paint has been removed from the mating faces, such as the
machine mounting feet, flange, ...
● There is no condensation present within the machine.
Setting down the machine
● Set down the machine slowly and carefully at the installation location to avoid any impact.
5.2.8 Drain condensate
In the bearing shields at the DE and NDE, water drain holes are situated in the foot area and
opposite the regreasing system. They are designed as follows:
● IP23 degree of protection: Water drain holes open
● IP54 / IP55 degree of protection: Water drain holes sealed with plastic plugs
Where drain holes in the foot area are sealed, it can be useful to remove the appropriate screws
or plugs depending on the ambient and operational conditions.
Note
Degree of protection for motors with IP54 and better
Removing the plastic plug or the plug screw from motors with IP54 or better nominally lowers
the degree of protection to IP44.
5.2.9 Roughly aligning the machine
Requirement
The transmission element such as a coupling half has already been pulled on.
Roughly aligning the machine
● For horizontal positioning, push the motor sideways across the foundation. When doing so,
ensure that the axial position is maintained.
