5.5 Rectifier Installation

The rectifiers are shipped in separate containers. Follow the procedure below to install a rectifier.

1)Remove the rectifier from its shipping box.

2)Slide the rectifier into the shelf between the guides until fully seated.

3)Fasten the rectifier in place with the rectifier retaining screw included in the shipment. Since all adjustments are made from the system control unit, no rectifier adjustments are necessary.

NOTE: All “FLOAT” – “BOOST/EQUALISE” switches (one is located on the front of each rectifier in the system) must be set to “FLOAT” to allow the MX28B to control the output voltage properly.
