7 Troubleshooting
7.1 Problems and Solutions
The modular, plug-n-play nature of this plant makes diagnostics and repair very easy. Make sure
that all power modules are properly seated and latched into their respective slots. Make sure that
all power and signal connectors are properly mated. Table 13 lists problems and potential solutions.
7.2 Short circuit & Current Limit
ILimit can be adjusted up to +105% of the rated current of the power module. The system voltage
will remain constant up to ILimit at which point the system voltage will drop quickly toward 0 VDC,
as in Figure 15. Once a 24V or 48V power module drops below 12 VDC for more than 5 seconds,
the system will shut down. For a 12V system, once the power module drops below 4V for more than
60 seconds, the system will shut down. The system will automatically restart after 60 seconds, and
will continue until the short circuit is cleared.

Table 13 - Problems and Solutions
Solution
Replace bad power module unit - unlatch, remove and replace with spare.
System short circuit - inspect and replace load and wiring.
Reset commercial circuit breaker to the dedicated AC circuit that feeds system.
Seek alternative power source until power is restored.
Power module has shut down because it has exceeded the maximum rated
temperature. The power modules will automatically restart.
