If the DX transformer does not power on THE LOW VOLTAGE TERMINALS when plugged into a working outlet, the internal fuse may need to be replaced. NOTE: The front panel will still show power. To protect the DX from ground surges caused by lightning or damaged connections, there is a fuse at the top of the transformer. This fuse does not protect the incoming voltage, just the low-voltage side of the transformer. The DX fuse is located in the top-wiring compartment of the transformer. Replace with a UL Listed 3AG with the following specifications: 10 Amp – 250V.
This procedure should only be performed by a licensed electrician. Disconnect power from the primary and secondary.
Remove power by unplugging the transformer. Use a flat bladed screw driver to remove cover.
Twist the two sides of the fuse holder in opposite directions to open.
Open fuse holder to change fuse.
