3.9. Rectifier Module Installation

WARNING: Rectifier 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.

3.10.Initial Power-Up and Checkout

Before initiating power-up and checkout, ensure that the following conditions exist:

1)Make sure that the external circuit breaker protecting the cables from the battery to the power plant is turned OFF (the battery cables should be connected to the power plant, but the battery should not be connected).

2)Make sure that all load circuit breakers are turned OFF (including the one feeding the GMT fuses if the unit has the GMT fuse option).

3)Verify that all rectifiers have been installed.
