Output
Note
The time that it takes for the output pair inv
olved to cool down depends on the ambient
temperature.
1. Allow the output pair involved to cool down.
After cooling down, LEDs "ON/OFF/RST"
② of the output pair, flash red.
2. Press the buttons of the outputs involved.
The temperature shutdown is reset, and the output is switched-on again.
Overtemperature monitoring of the battery modules
The temperature values of the battery module are transferred to the system via the UPS
module.
If the temperature of a battery module exceeds the permitted value, a signal is generated
and the "O.K." LED at the battery module flashes yellow. The corresponding battery module
is no longer charged. The battery module can be discharged.
Note
Cyclic and complete
discharge and charge cycles in operation cause the temperature of the
BAT8600 LiFePO4 battery module to increase. In order to avoid deactivating the BAT8600
LiFePO4 battery module, the subsequent cooling
-dow
n times should be maintained between
complete charge followed by complete discharge operations.

Note
Charging is stopped for ambient temperatures of the BAT8600
Pb and BAT8600 LiFePO4
battery modules >
50 °C.
At ambient temperatures of the BAT8600 Pb battery modules between 40
°C and 50 °C, the
charge power is automatically reduced down to 60
W if only one battery module is connected
to the UPS module.
