Chapter 6 Routine Maintenance

6.1Maintenance Of Rectifier

The fan of rectifier shall be maintained periodically.

The fan shall be replaced if it does not work due to faults.

Follow the procedures below to replace the fan:

1.Loosen the 3 screws on the baffle and remove the baffle.

2.Unplug the power cable of the fan and remove the fan.

3.Replace the fan.

4.Plug the fan power cable back into the corresponding socket.

5.Push back the fan (the side with the tag facing inward).

6.Mount the front baffle and fix it with screws.

6.2Maintenance Of SCU

If any SCU fault affects the normal operation of DC power system, just turn off the SCU.

6.3Maintenance Of MFU

1. Short-circuit of load

If some of the loads have short circuit fault, just turn off the circuit breakers in the MFU to disconnect the power to the loads.

2. MFU short-circuit

When MFU short-circuit occurs, disconnect the AC power supply, isolate the batteries from the system, and then use battery or rectifier to directly supply power to load.
