Attach Pad Mounting Bracket to Lifting Nut
Because it is generally inadvisable to drill holes into the transformer housing,
you use one of the 1.6 cm (5/8 inch) welded lifting nuts (inside the transformer
cabinet and exposed through a hole in the transformer casing) as the installation
point.
Locate one of the transformer’s lifting nuts. There is no standard for the location
of the lifting nuts, but typically one is within a few centimeters (an inch or two) of
the top of the transformer.
Measure the distance from the lifting nut to the top of the transformer, and
extend the Pad Mounting Bracket to ensure that after the bracket is attached to
the lifting nut, the top of the bracket is as close to the top of the transformer as
possible.
To secure the ECN to the transformer’s lifting nut, temporarily remove the nut.
Position the Pad Mounting Bracket so that one of the horizontal slots matches
the position of the lifting nut. Attach the Pad Mounting Bracket to the lifting
nut. Figure 17 on page 40 shows the Pad Mounting Bracket attached to the
lifting nut.
After you secure the Pad Mounting Bracket to the lifting nut, secure the bracket
to the transformer pad using the two 1.6 mm (5/8 inch) slots at the bottom of the
bracket.
