WARNING!
All electrical work shall carried out in accordance with the local and
national electrical norms and should follow the important safety
precautions contained in this manual.
WARNING!
Make sure that suitable connecting cables are used for both the AC
and DC wirings. The cable must be adequately dimensioned and
suitably inert to temperature fluctuation, UV radiation and other
possible hazards. For DC wiring connection to the ISMG3 inverter,
use 10 to 16 mm
2
(#8 to #6 AWG), 90°C (194°F) copper wire; For AC
wiring connection, use 6 to 10 mm
2
(#10 to #8 AWG), 90°C (194°F)
copper wire.
WARNING!
PV arrays will be energized when exposed to light. Cover the arrays
with opaque (dark) material during installation and wiring and make
sure the DC switch is on OFF position (as in fig.2.3.1)
Before wiring the ISMG3 inverter, it is necessary to determine the utility
configuration that the inverter will be connected to. The ISMG315 and ISMG320
inverters shall be used in three-phase utility interconnection with neutral as well
as the ground as shown in Fig 2.3.6.
