Important Installation Note

Each transformer is supplied with a dished washer and protection pads for single hole fixing. Ensure that the pads are fitted above and below the transformer winding and that the dished washer is on top of the upper pad. Do not over tighten the fixing bolt (not supplied) as this could damage the winding.
Under no circumstances should both ends of the fixing bolt contact a metal chassis or frame as this would create a &squot;shorted turn&squot; causing irreparable damage.
