9. MAINTENANCE
In case of too low temperature, the LE heats up, once the system gets charged.
In case of too high temperature, the LE will reactivate, once temperature is lower.
The LE300 itself is fine, but either the short circuit or the wrong polarity protec-
tion was triggered. Please check the wiring for short circuits or wrong polarity
connection.
Red LED flashes, if temperature is too high or too
low (<-40 °C or >60 °C). If no LED turns on once
the push button was pushed, please contact your
BOS dealer.
Why is there no voltage at the power connector of the LE?
The device is basically maintenance-free. Cable connections should be checked
frequently. Clean the device from dust when necessary with a dry cloth. Avoid any
contact with water or other liquids.
The lifespan of the LE300 can be prolonged when being properly maintained and
especially when being operated and stored at the right temperatures.
With increasing age however, the LE300 capacity will diminish even when pro-
perly maintained.
If the operating period significantly reduces after charging, the LE300 is probab-
ly worn out and must be replaced.
As long as the LE300 is not connected to a lead acid battery, the power connec-
tor of the LE300 is deactivated. In order to use the LE300, connect it to a 12 V
lead acid battery.
