Connecting a Drum Motor
Equipped with a Backstop (TB) Device
1.
Look for the brass arrow on the end flange . It will indicate which direc-
tion the drum motor will rotate .
2.
Mark the three incoming power supply leads with numbers L1, L2, L3 .
Ensure that the ground lead is properly connected to the ground .
3.
Connect the incoming power supply leads:
L1 to motor lead #1
L2 to motor lead #2
L3 to motor lead #3
4.
Turn the power to the motor ON and OFF, (no more than 0 .5 second on
the ON position) . If the motor rotates then the connection is correct and
you can proceed to step 5 . If the motor does not rotate, interchange any
of the two power supply leads .
Example: L1 to motor lead #2
L2 to motor lead #1
Turn the power ON and the motor should rotate in the correct direction .
Change the markings on the incoming power supply leads to correspond
with the motor leads .
Example: L2 to be changed to L1 and
L1 to be changed to L2 .
Before Step 4 is complete, the motor should be running in the correct
rotation and the connection should be as follows:
Power supply Motor Leads
L1 to 1
L2 to 2
L3 to 3
When that is completed, proceed to step 5 .
5.
Finalize the motor connection:
Power supply Motor Leads
L1 to 1
L2 to 2
L3 to 3
6.
Turn ON the motor .
