3.9. Rectifier Module Installation

WARNING: Rectifier DC output circuits will be damaged if

battery is 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 generally shipped in separate containers. Follow the procedure below

to install a rectifier module. Rectifiers may be installed even when the system is energized.

1) Remove the cover plate (if present) from the position where the rectifier will be added.

2) Remove the rectifier from its shipping container.

3) Slide the rectifier module into the shelf between the guides until it is fully seated.

4) Fasten the rectifier in place with the captive rectifier retaining screws.

5) Enable that rectifier position for monitoring by removing the system Controller Board and

setting the dipswitch S2 position corresponding to the new rectifier position from “ON” to

“OFF” (if there are 10 little switches then the operate in pairs. The rectifiers are

numbered on the top row, left to right as 1 through 5; and on the bottom row, left to right 6

to 10, when facing the front of the system. See Section 5 for additional details

concerning the setup of the system Controller Board.

Since all adjustments are made from the system controller, no rectifier adjustments are

necessary.

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 are 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 and fuses are removed.

3) Verify that all rectifiers have been installed.

4) Apply AC Power by turning on the circuit breakers that supply AC power to the

rectifiers in the power plant.
