Belt Drives; Cabling And Electrical Connections - ABB M3BL 160 Manual Del Usuario

3. INSTALLATION AND COMMISSIONING

3.6 Belt drives

Check that the motor shaft is parallel with the
drive shaft.
Belts must be tensioned according to the
instructions of the supplier of the driven
equipment. However, do not exceed the
maximum belt forces (i.e., radial bearing
loading), which can be requested from ABB.

3.7 Cabling and electrical connections

The terminal box on a standard HDP motor
normally contains winding terminals and at least
one earthing terminal.
In addition to the main winding and earthing
terminals, the terminal box can also contain
connections for thermistors, heating elements
or other auxiliary devices.
The picture below provides an overview of
a standard terminal box:
The size and interior layout of the terminal boxes
may differ depending on the motor size, the rated
power, and certain optional accessories.
Suitable cable lugs must be used to connect all
primary cables.
EXCESSIVE BELT TENSION WILL
DAMAGE THE BEARINGS AND MAY
CAUSE DAMAGE TO THE SHAFT.
WARNING
The machines are intended for fixed installation
only. If not otherwise specified, cable entry
threads are metric. The IP class of the cable gland
must be at least the same as that of the motor.
Unused cable entries must be sealed with blanking
elements according to the IP class of the motor.
USE CABLE GLANDS AND SEALS
IN THE CABLE ENTRIES WHICH
ARE SUITABLE FOR THE TYPE AND
DIAMETER OF CABLE BEING USED.
WARNING
Earthing must be carried out according to local
regulations before the machine is connected to
the supply voltage.
It is recommended to perform the installation of
the motor observing the grounding and cabling
instructions required by the frequency converter.
When preparing the installation, select the size of
the power cables according to the current load.
Ensure that the motor protection corresponds
to the environment and weather conditions;
for example, make sure that water cannot enter
the motor or the terminal boxes.
The seals of terminal boxes must be placed
correctly in the slots provided to ensure they suit
the correct IP class.
