Storage - DEMA D5M Series Manual

NO.1 Safety Cautions
● It is prohibited to enable or disconnect motor unit during the running of inverter, so as to
prevent overcurrent tripping even burning the main circuit.
● It is prohibited to remove the front cover of inverter during energizing to prevent electric
shock causing personal injury.
● When the failure restart function is started, the motor will restart automatically after the
running stops; please keep away from the machine at this time to avoid accident.
● Stop switch will not be enabled until being set, which is different from the emergency switch
in use, please pay attention to it.

1.4 Storage

● Temperature of the storage environment shall range from -20℃ to +65℃;
● Relative humidity of the storage environment shall range from 0% to 95% in dry place
without condensation or dust;
● There shall be no corrosive gas and liquid in the storage environment, it shall be put on
shelter preferably with proper package;
● Long-term storage of inverter may cause deterioration of electrolytic capacitor, so it is
necessary to switch it on over 5h once a year at least, and the voltage must rise to rated
voltage value via a voltage regulator when inputting.
