* Allow an extra 4mm height for mounting discs, and allow 5mm extra diameter at positin of leadouts.

Important Installation Note Where transformer is supplied with a dished washer and protection pads for single hole fixing, the installer must 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 overtighten 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 'shorted turn' causing irreparable damage.
