Operating temperature 0–40°C
CAUTION
● When the operating temperature is beyond the range of 0°C to 40°C, the
power backup capability of the system may be unavailable or not reach
the rated value.
● When the operating temperature is below 0°C, the battery modules
switch o the charge and discharge circuits. As a result, the battery
modules cannot be charged or discharged. Start the air conditioner to
heat the battery modules to 3°C or above, and the charge and discharge
will be resumed.
Storage temperature 0–60°C
Relative humidity 5%–95% RH (non-condensing)
Altitude 0–4000 m (When the altitude ranges from 0 m to 1000 m, the
power is not derated. When the altitude exceeds 1000 m, the power
is derated as described in IEC 62040-3.)
