I have acquired 2 new/in the box ITR2000 115/230 volt| 16W/8 Amp Isolation Transformers that upon further inspection appear to have loose coils on the coil "ID" mounting posts attached to the back-side of the Housings. I can see that the coils have come detached from the mounting posts and have some movement on the post while enclosed in the Isolation Transformer. Is the Posts/Position critical to the function of the Isolation Transformer? Can I simply re-attach/ secure the coils to prevent any further movement of the coil inside the Isolation Transformer?
