Replacing the Rectifier Module
1 At the defective rectifier module, set the AC INPUT and DC OUTPUT circuit breakers to OFF.
2 On the modular power supply shelf (rectifier shelf), loosen the two captive fasteners, and pivot the module
retainer downward.
3 Grasp the rectifier module by the handle (at top) and pull the module out of the rectifier shelf.
4 Insert the replacement rectifier module in the shelf. Push firmly so that the connector is fully seated. Verify
that the AC ON LED is lighted red.
5 To secure all modules in the rectifier shelf, pivot the module retainer upward and tighten the captive fasteners.
6 Power up the replacement module: first set the DC OUTPUT circuit breaker to ON; then, set the AC INPUT
circuit breaker to ON. Verify that the AC ON LED changes from red to green.
7 If there are no rectifier alarms, turn the other rectifier module off by first setting the AC INPUT circuit breaker
to OFF, then setting the DC OUTPUT circuit breaker to OFF.
8 Adjust the float voltage on the new rectifier as shown in Figure 40 on page 45 .
9 At the other rectifier module, first set the DC OUTPUT circuit breaker to ON; then, set the AC INPUT circuit
breaker to ON.
Replacing the Alarm and Control Assembly
1 If fuse F1 has failed, replace it with a Bussmann GMT-1/2 fuse.
2 On the rectifier shelf, loosen the captive fasteners, and pivot the module retainer downward. Remove the
blank cover plate(s) (if present).
3 At the right side of the rectifier shelf, locate remote alarm connector P1; disconnect it from ACA connector
J1. Access to J1 is through the shelf side opening; J1 is the connector nearest the front of the ACA.
4 Loosen the captive fastener on the ACA, and remove the ACA.
5 Install the replacement ACA in the rectifier shelf; tighten the captive fastener.
6 Locate remote alarm connector P1, and connect it to ACA connector J1.
7 Replace the blank cover plate(s).
8 Pivot the module retainer upward, and tighten the captive fasteners.
The modular power supply requires no routine maintenance. To replace a rectifier module,
perform Step 1 through Step 9. To replace the Alarm and Control Assembly (ACA) or fuse F1,
perform Step 10 through Step 17.
The rectifier module is very heavy and may be warm. Support the module with one hand during
removal.
