Rectifier Module Installation

WARNING: Rectifier dc output circuits would be damaged if battery were installed incorrectly. Before rectifier installation, ensure proper battery polarity.

Rectifier modules are hot-swappable. The rectifier modules are generally shipped in separate containers. Remove the rectifier from its shipping container. Using a flat blade screwdriver, loosen the pawl latch (counter-clockwise) on the rectifier, until the latch is recessed inside the rectifier. Slide the rectifier module into the shelf between the guides until it is fully seated. Tighten the rectifier pawl latch (clockwise). The pawl latch is a multi-turn device and should be turned until the latch holds the rectifier snugly. Since all adjustments are made from the system control unit, no rectifier adjustments are necessary.

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.

Fan inlet filters are available for order from APC (Part Number 1MAF28).
