11. Troubleshooting
The rectifiers and the shelves are designed for simple installation and reliable, trouble-free operation for several
years.
In most cases the rectifiers will recover from minor alarms and faults automatically. However under certain conditions
the rectifiers may need remote control. And under very rare cases the rectifier may need a manual reset (unplug and
reinsert the rectifier). In the unlikely event of a rectifier failure, it may need replacement.
A 3.0KW rectifier shelf can have 4 or 5 rectifiers in it, depending on the model. The rectifiers have 3 LED indicators
that provide information about the system. Refer to the LED section, 4.1.1 on page 11 for details.
When the 3.0KW shelf system is used in conjunction with a controller, detailed system informations and status can
be obtained through it. Even more information can be obtained using the web interface using the Ethernet port.
Table below provides a quick look up at the LEDs and the corresponding rectifier states.
