Original instructions
Connect to the Electrical Supply Source
The main electrical power supply connection for the MSB is made directly at the
junction box underneath the outer weather cover and below the ECM motor. Refer
to wiring detail and wiring diagrams in Appendix C. Remove the weather cover
from the MSB and wire directly to the power wires inside the outside junction box
located beneath the ECM motor. A knockout has also been provided on the side of
the j-box for this purpose.
Access the j-box by removing the top weathercover of the blower base. This
weathercover is held in position by machine screws, and once they have been
removed, you will have access to the j-box of your blower.
CAUTION: Inspect the MSB blower nameplate voltage and
model number carefully prior to connecting your electrical
service. The wiring harness determines the voltage. The 115V
harness is 7115300 and the 230V harness is 7115301 per wiring
diagrams in Appendix C.
ATTENTION: Vérifiez la tension nominale ventilateur MSB et
le numéro de modèle attentivement avant de brancher votre
service électrique. Le câblage détermine la tension. Le harnais
de 115V est 7115300 et le faisceau de 230V est 7115301 par les
schémas de câblage à l'annexe C.
The blower base end panel is positioned above the blower base to allow for a
continuous flow of cooling air through the motor cavity. Slots and louvers have
also been placed on both the front and back of the blower base to provide airflow
through this motor cavity. Because there is a gap between the end panel and the
base, you will be able to run your electrical conduit directly underneath this panel.
No special cutouts or modifications are necessary.
NOTE: WHEN THE WIRING FOR YOUR BLOWER HAS
BEEN COMPLETED, CHECK FOR PROPER MOTOR
ROTATION. THE MOTOR SHOULD OPERATE IN A
CLOCKWISE ROTATION AS VIEWED FROM THE SHAFT
SIDE TO OBTAIN PROPER ROTATION OF THE IMPELLER
WHEEL. WHEN IN OPERATION, THE IMPELLER SHOULD
ROTATE COUNTERCLOCKWISE WHEN VIEWED FROM
THE BLOWER INLET. 
