PV array string input connections (Only for DC-coupled
type)
DANGER
To ensure maximum protection against hazardous contact voltages while assembling photovoltaic
installations, both the positive and the negative leads must be strictly isolated electrically from the
protective ground potential (PE).
WARNING
y
Risk of electric shock and fire. Use only with PV modules with a maximum system voltage rating
of 450 V or higher.
y
Electric shock hazard. The DC conductors of this photovoltaic system are ungrounded and may
be energized.
y
Electric shock hazard. The DC conductors of this photovoltaic system are ungrounded but will
become intermittently grounded without indication when the inverter measures the PV array
isolation.
CAUTION
Verify DC conductor voltage polarity with voltage meter because damage to the inverter could
result if the incorrect DC input polarity is connected.
CAUTION
Risk of damage. Be sure that the polarity is correct when you make the connection. Connecting it
incorrectly will cause damage to the inverter.
INFO
The PV Array positive or negative leads must not be connected to ground before the inverter.
INFO
All terminals accept solid or stranded copper 14 –8 AWG wire only. A 1/8” (3.5 mm) flat blade
screw driver is recommended for tightening screw terminals to a 10.5 in-lbs. (1.2 Nm) torque.
