Each transformer is supplied with a dished washer, protection pads and nut, bolt and washer for single hole fixing. The pads are to be fitted above and below the transformer winding and the dished washer on top of the upper pad.
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.
THESE TRANSFORMERS DO NOT PROVIDE ISOLATION FROM MAINS. |
