4.5 Other Tests

For Australian requirements, in the THDi test, Zref should be added between the inverter and
mains.
RA, XA for the line conductor
RN, XN for the neutral conductor
Zref:
RA = 0, 24, XA = j0,15 at 50Hz
RN = 0, 16, XN = j0,10 at 50Hz

4.6 Quick Checklist To Avoid Dangerous Conditions

1. The inverter must not be installed near flammable or explosive materials or near equipment
with strong electromagnetic fields. Please refer to page 6.
2. Remember that this inverter is heavy! Please be careful when lifting from the package. Please
refer to page 07
3. Make sure that the battery breaker is off and that the nominal battery voltage meets ET specifi-
cations before connecting the battery to the inverter; make sure that the inverter is totally
isolated from both PV and AC power. Please refer to page 9.
4. Make sure that the inverter is totally isolated from all DC or AC power before connecting the AC
cable. Please refer to page 11.
5. Make sure the AC cable is totally isolated from AC power before connecting the Smart Meter and
CT. Please refer to page 14.
