INSTALLATION AND START-UP
PRECAUTION
Damage caused to bearings as a result of long storage periods
If the machine has been stored for more than 3 years in good conditions (dry, dust-free place, etc.), the grease
on the bearings must be changed, if they need re-greasing, or the bearing should be changed if it is a bearing
with lubrication for its entire service life. If the machine has been stored in poor conditions, the change or re-
greasing of the bearings may be necessary before the aforementioned period.
The following describes the conditions that are necessary for the installation and start-up of the machine.
5.1
Motor installation
5.1.1
Site
A correct site is essential for guaranteeing a long motor service life. The use of the motor in an incorrect site
could shorten its service life considerably. The following are some points to bear in mind when choosing the
correct site for the motor:
a)
The chosen site must comply with the ambient temperature range and altitude for which the motor was
selected (for more details, see section 3.5.3).
HOT SURFACE
The exterior surface of the motors can reach temperatures of more than 60°C and, therefore, the appropriate
precautions must be taken to avoid accidental contact.
b)
The site must have a humidity level of less than 85% to prevent condensation appearing on the surface.
c)
The air inlet and outlet must not be blocked. There must be no recirculation of hot air from the outlet to
the inlet.
PRECAUTION
Damages caused to the motor by blocking the airflow at the motorised fan inlet
Damages may be caused to the motor if there is an insufficient airflow at the motorised fan inlet due to the
selection of an incorrect site for the machine. If the machine does not have sufficient cooling airflow, the
windings may overheat and the corresponding consequences may arise.
