5.8.3.5 Toroidal Transformer
To replace the elevating base toroidal transformer:
1. Disconnect the wire harnesses connected to the relay board and remove the board.
2. Using an 1/2” open end wrench loosen transformer retaining bolt.
3. Remove both the toroidal transformer and the retaining bolt. Save the bolt for installing the replacement
transformer.
4. Disconnect the old transformer from its wire harness.
5. The replacement toroidal transformer comes with two 4” diameter rubber insulating washers that are
installed on both sides of the transformer like a sandwich, and a 4” diameter metal mounting washer that
is installed on the same side of the transformer as the head of the retaining bolt. To make aligning these
parts easier during installation, you may wish to use electrical tape to attach the 3 large washers to the
transformer.
6. Install the new transformer by passing the retaining bolt through the washers and transformer and into the
threaded hole in the side of the electrical enclosure. Turn the transformer so you can see the label on the
side transformer to orient the wire harness so it exits toward you, then nish tightening the retaining bolt.
7. Connect the transformer wire harness.
8. Reinstall the relay board and reconnect its wire harnesses.
5.8.3.6 Circuit Breakers, Power Switches, and Power Outlets
The circuit breakers, power switches and power outlets can all be more easily accessed by removing the
connection panel at the bottom of the enclosure by removing the 3 screws that secure it with a 2.5 mm hex
key.
