To ensure the proper working conditions for the uninterruptible power supply system, the room with
the power supply must be clean, free of dust and dirt.
From time to time (at least every 6 months or more often depending on the degree of soiling), clean
the ventilation holes on the power supply to ensure free air flow.
To extend battery life, the ambient temperature should be between 15-25 ° C.
