how long the module has been used. Therefore, a stable power source is
important for system operation.
2.
The charger circuitry implemented with the controller has failed.
There are other conditions that might trigger BBU fault events and the BBU
fault LED:
1. The temperature sensor on the system's charger circuit reports a
temperature reading exceeding the pre-set threshold. The charger
circuits will enter a low-power and self-protection state.
2. A BBU module has been charged for over twelve (12) hours. A timer is
embedded with the charger. When this occurs, the charger will enter a
timer fault state. This condition usually occurs with a brand new BBU or
with a totally discharged BBU. Charging will resume automatically if you
remove/re-install the BBU module or reset the system.
5.4.2 BBU Warnings and Precautions
Install or replace the BBU with BBUs supplied by your vendors only. Use
of battery cells provided otherwise will void your warranty.
Always dispose of a replaced battery in an ecologically responsible
manner. Dispose of used BBUs at authorized battery disposal sites only.
Do not place a BBU near a heat source. Heat can melt the insulation and
damage other safety features of battery cells, possibly causing acid leak
and result in flames or explosion.
Do not immerse the BBU in water nor allow it to get wet. Its protective
features can be damaged. Abnormal chemical reactions may occur,
possibly causing functional defects, acid leak, and other hazardous
results.
Do not disassemble or modify the BBU. If disassembled, the BBU could
leak acid, overheat, emit smoke, burst and/or ignite.
Do not pierce the BBU with a sharp object, strike it with a hammer, step
on it, or throw it. These actions could damage or deform it and internal
short-circuiting can occur, possibly causing functional defects, acid leak,
and other hazardous results.
If a BBU leaks, gives off a bad odor, generates heat, becomes discolored
or deformed, or in any way appears abnormal during use, recharging or
storage, immediately remove it from the system and stop using it. If this
is discovered when you first use the BBU, return it to your system
vendor.
