WARNING The rectifier contains voltages that may be lethal even
after the input supply has been removed.
WARNING The rectifier contains components at high temperature
that may burn if touched

Troubleshooting
Basic operation checks:
•
Check power to the rectifier – check that the Mains LED is on
•
Check and resolve any fault conditions indicated by the rectifier
•
Check that the display on the rectifier is showing that the rectifier is delivering
current
•
Disconnect load and battery leads. Connect a load to the battery terminals.
Check the voltage across the load is as expected
•
Connect a current meter in series with the load. Adjust the load and check the
current delivered by the rectifier is as expected
Load Checks:
•
Connect battery but disconnect the main load to rectifier. Connect a current
meter in series with the battery. Verify the current drawn by the battery from the
rectifier is as expected. Check that the battery takes the charge.
•
Connect the main load to the rectifier (mains off) and disconnect the battery.
Turn the mains on and check that the current drawn by the load is as expected,
and within the capabilities of the rectifier and battery.
Fine Adjustment Checks: (see section on adjustments for instructions)
•
Check Boost and Float voltages
•
Check Boost to Float current
•
Check Temperature Compensation Slope
•
Check LVD operation

Fuses
Although there are fuses inside the rectifier, these are rated such that their failure
indicates a fault requiring qualified service.
Do not attempt to repair these fuses.
However, for IEC 60950 the fuse ratings are required to be specified.
