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 (the motor bears a plate indicating said circumstance).
b)
The site must have a humidity level of less than 85% to prevent condensation appearing on the surface. If the humidity
levels at the site exceed 85%, the motor must be fitted with anti-condensation heaters (see section 3.7.6).
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 motor air-inlet
Damages may be caused to the motor if there is an insufficient airflow at motor air-inlet. If the machine does not have sufficient
cooling airflow, the windings may overheat and the corresponding consequences may arise.
