•
As a minimum, check that the float voltage and load current is as expected.
•
If the batteries are fully charged, check the battery current is zero or near to zero amps, and check that the amp-hours
remaining is 100%.
9.3.
Rectifiers and Converters
•
During normal operation some dust will build-up on the front of the rectifiers. This should be kept to a minimum by
regularly wiping the rectifiers to avoid accumulation within the rectifiers and blocking the airflow to the units. The
positioning of the system and surroundings will determine the regularity of this requirement.
•
In extremely dusty positions it is recommended that the units are removed and cleaned with compressed air to prevent
airflow blockages.
•
Check the air flow front and back to the rectifiers is unimpeded by cables or otherwise.
•
Check nothing has entered the rectifiers such as insects or geckos.
9.4.
Batteries
•
Battery maintenance depends on the individual manufacturer’s specification, please contact the battery supplier for
recommendations.
•
Periodic discharge tests may be beneficial to ensure reliable system operation and may be recommended by the battery
manufacturer.
CAUTION - The user must be aware of the consequences of battery State of Health (SoH) with regards their
specific load requirements and implement their own policy regards the end of life of the batteries.
9.5.
Ventilation Maintenance
Check that there has been no change in the required airflow space or environment that impacts the ventilation.

TROUBLE-SHOOTING AND SERVICING
If the red LED is alight:
•
Unplug the rectifier and re-engage.
•
Check AC power to the rectifier.
•
Check for rectifier alarms in the monitor Urgent Alarm list.
•
If symptoms persist, contact a service agent.
If the yellow
LED is alight:
•
Check the monitor Non-Urgent Alarm list.

Servicing
DANGER - Do not operate the rectifiers, converters, or other power modules if the covers are damaged or
removed in any way.
WARNING - The rectifiers, converters or other power modules contain voltages that may be lethal even
after the input supply has been removed.
WARNING - The rectifiers, converters or other power modules contain components at high temperature
that may burn if touched
To isolate a rectifier or converter from the power supply, unplug it from the shelf.
The power modules contain no user serviceable components. Do not disassemble the modules.
If a power module has an operational fault or is damaged in any way, an authorized service center should service it
