S8BA-LF Do not exceed the ranges specified for environmental conditions during use/storage. Do not install or store the unit in the places listed below. • Do not store in places where the humidity is lower than 10% or higher than 90%. • Do not use the unit in places where the ambient temperature is lower than 0°C or higher than 55°C. (With no condensation) • Do not use in places where the humidity is lower than 10% or higher than 90%.
S8BA-LF (for maintenance) When maintaining the connected equipment, turn OFF the unit’s “Power” switch to stop the output, and stop the supply of the “input power supply”. • Even if the input power supply to the UPS is stopped while it is in operation, the power output of his unit does not stop and power is supplied from the battery. Do not disassemble, repair, or modify the unit. • Doing so may cause an electric shock or a fire. If fluid leaks from the interior, do not touch the fluid.
S8BA-LF For Storage Face-up mounting To store the UPS for a long time, store it in an environment where the ambient temperature is 25°C or lower, and charge the battery once every year for 10 to 15 minutes. • The battery discharges itself even if it is not used. If the battery is left unused for a long time, it goes into a state of over-discharge. In such a case, the backup time may become shorter, or the battery cannot be used anymore.
