3-4-3 Neutral Grounding Connection Settings ( models after 2021)
The default setting is option A: NO CONNECTION BETWEEN NEUTRAL CONDUCTOR (N) OF THE
AC OUTPUT AND SAFETY GROUND (PE/GND)
SC-1200/2000
Rear side of the inverter/ charger
SC-3000
Left side of the inverter/charger
CAUTION
It is advised that all the electrical installation should conform to the local electrical codes and
should be carried out by a certified 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.
