NOTE: If the battery temperature is higher than the threshold
after a full discharge at maximum continuous discharge power, the
UPS may have to reduce the charge current to zero to protect the battery.
NOTE: The battery temperature must return to room temperature ±3
°C (5 °F) before a new discharge at maximum continuous discharge
power. If not, the battery breaker may be tripped due to overtemperature
protection.
NOTE: The working temperature for the busbars should
be no more than
100 ℃ (212 °F).
100 ℃ (212 °F).
