by the supplier is operator installable and may be operated by
laymen.
The mains socket outlet that supplies the UPS shall be
installed near the UPS and shall be easily accessible.
During the installation of this equipment it should be assured
that the sum of the leakage currents of the UPS and the
connected loads does not exceed 3.5mA.
Connection to any other type of receptacle other than a
two-pole, three-wire grounded receptacle may result in shock
hazard as well as violate local electrical codes.
In the event of an emergency, press the "OFF" button and
disconnect the power cord from the AC power supply to
properly disable the UPS.
Do not allow any liquids or any foreign object to enter the
