3.11. Rectifier Module Installation
WARNING: Rectifier DC output circuits would be damaged if battery were
installed incorrectly. Before rectifier installation, ensure proper battery
polarity and that the battery is isolated from the rest of the system
The rectifier modules are shipped in separate containers. Follow the procedure below to install
a rectifier module.
1) Remove the rectifier from its shipping container.
2) Remove any rectifier retaining screws from the shelf position where the rectifier is to be
installed.
3) Slide the rectifier module into the shelf between the guides until it is fully seated.
4) Fasten the rectifier in place with the rectifier retaining screw (included in literature kit with
product manual).
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.
CAUTION: Rectifier fan inlet filters are available for dusty or hostile
environments. Failure to periodically check and clean filters can lead to
rectifier shutdown due to over temperature and produce power plant failure.
