Rated Vs. Actual Current Of Loads - NDS Smart-in SM Series User Manual

• Turn the appliance on.
• Plug in additional appliances and turn them on.
Notes: 1. Plug the cord from the AC appliances you wish to operate into the
AC receptacle. When turn ON the inverter the Red and Green LEDs both lit for
3~5seconds then the red LED not lit, the green LED indicator lights to indicate
that the inverter is functioning. Make sure the combined load requirement of
your equipment does not exceed the output rating of the inverter.
• Turn OFF the inverter. The over load LED may briefly "blink" and the audible
alarm may also sound a short"chirp." This is normal. This same alarm may also
sound when the inverter being connected to or disconnect from the battery.
• When using an extension cord from the inverter to an appliance the extension
cord should not be longer than 1,5m and with appropriate section.
• When you plan to operate more appliances, please make sure plug and switch
ON the biggest one first and then smaller ones.
Caution: The inverter is engineered to be connected directly to standard
electrical and electronic equipments. Do not connect the power inverter to
household AC distribution wiring. Do not connect the power inverter to any
AC load circuit in which the neutral conductor is connected to ground (earth).

10. RATED VS. ACTUAL CURRENT OF LOADS:

Most electrical tools, appliances and audio/video equipment have labels that indicate
the power consumption in amps or watts.
Be sure that the power consumption of the item you wish to operate is less than
inverter's rating power.( if the power consumption is rated in amps, simply multiply
by the AC volt (220V) to determine the wattage). The inverter will shutdown if it is
overloaded. The overload must be removed before the inverter will restart.
Resistive loads are the easiest for the inverter to run. However, larger resistive loads,
such as electric stoves or heaters, usually require more wattage than the inverter can
deliver. Inductive loads. Such as TV's and stereos, require more current to operate
than do resistive loads of the same wattage rating. Induction motors, as well as some
televisions, may require 2 to 6 times their wattage rating to start up. The most
demanding in this category are those that start under load, such as compressors and
pumps. To restart the unit after a shutdown due to overloading, remove the overload
if necessary turn the inverter OFF and then ON.
