If any of the following occurs, the PMU is faulty:

1. The PMU breaks down or fails to start, or its LCD or keyboard fails.

2. The PMU does not generate an alarm when a fault occurs in the system.

3. The PMU generates an alarm (false alarm) when the system runs properly.

4. Communication between the PMU and all subordinate equipment is interrupted.

5. The PMU fails to control or monitor all the modules when these modules run properly

and communications cables are connected properly.

6. The PMU fails to monitor or control AC or DC distribution when AC/DC power is

distributed normally and communications cables are connected properly.

7. Parameters cannot be set or operating information cannot be viewed on the PMU.

5.3 Component Replacment

Describe how to replace the main components of the power system.

Load disconnection is prohibited when you replace the main components. Take measures to ensure

that important loads are always connected during the replacement. For example, keep the circuit

breaker of important loads set to ON and storage batteries and AC input are not cut off.

If a load must be disconnected, ask for the customer's prior permission.

The rectifier and the PMU are hot-swappable.
