Important Installation Note:

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.

Many of these transformers are available through distribution : See our Transformers in Distribution page and choose the Mounting Style “Open Style” from the drop-down list.
