Always check the phase torque at the output before connecting a load to the UPS output. In case of bad phase torque, some back-up appliances (pumps, fans, etc.) may be damaged.
Output Characteristics: the UPS output provides a clean sine wave with maximum load in accordance with the inverter datasheet.
Motor load: it is possible to connect a motor load provided that the maximum load is observed (but keep in mind the starting currents of electric motors).
