CAUTION!
It is advised that all the electrical installation should conform to the local electrical codes and
should be carried out by a certied technician. When the unit is feeding the internally inverted
voltage, the current carrying conductors connected to the “L” and “N” terminals of the AC
output will be isolated from the metal chassis of the inverter. Hence, during this condition, when
the metal chassis of the inverter is connected to the earth ground, the “N” terminal of the AC
output will not be grounded (bonded) to the earth ground. Under this condition, the “N”
terminal of the AC output will not be a Neutral in the true sense. Do not touch this terminal as
it will be at an elevated voltage (almost half the value the AC output voltage) with respect to
the metal chassis / earth ground and may produce an electrical shock when touched!
When the unit is transferring power from the AC input source, the grounding condition of the
“N” terminal of the AC output will be the same as the condition of the “N” terminal of the AC
input source. If the AC input source is the power supplied from the utility, the “N” terminal would
be a Neutral in the true sense. It will normally be bonded to the earth ground and will read
almost 0 V with respect to the earth ground. In this case, touching this terminal will not be a
shock hazard.
NOTE - In case the load current over the outlet rated current, please use the hard wire terminal
next to the outlets.
When using full power, it is recommended to use the wiring terminal.
