NOTE: A Universal Protractor is recommended for measuring the angles in the following
steps.
IMPORTANT: In the following steps, the protractor readings will be taken off of
vertical and horizontal surfaces; therefore, both the 0 degree and the 90 degree
marks will be used. It should be kept in mind that these are reference marks only and
the assigned numbers should be ignored. It is only necessary to determine the
number of degrees and to which side (left or right) of the reference marks the
indicator needle rests. PROTRACTOR MUST BE VIEWED FROM THE SAME SIDE OF
POWER PACKAGE THROUGHOUT INSTALLATION.
