The service life of the motor can be considerably reduced if the storage period extends beyond 2
years in environments with high moisture and dirt. If necessary, the insulation resistance of the
winding could be measured determine the health of the motor prior to installation and start-up, (see
Section 3.5. for reference values).
Machined surfaces (flange, DE rotor shaft) are treated at the factory with an anti corrosive agent to
prevent rusting. However these surfaces should be retreated during storage as deemed necessary. It
is recommended that the motor shaft is rotated by hand on a frequent basis to ensure even
grease distribution.
3.0 INSTALLATION AND
COMMISSIONING
All work must be carried out by a skilled worker.Before starting any work,
be sure to isolate the machine from the main and auxiliary power supply as
applicable.Mains must be secured against accidental switch on.
3.1 Installation
A fine foundation and exact installation is regarded as a basic requirement for coming long-time
reliable working. Inappropriate foundation or installation may cause abnormal motor vibration and
noise.
3.1.1 Foundation requirement
The foundation of installation can be a metal base or a platform of concrete structure, whatever
structure the foundation has, the foundation must have enough strength and rigidity in order to
support motors.
The design of foundation can refer to DIN 4024.
The supporting surface of the foundation must be flat, flatness of the supporting surfaces for
conventional motors
