Wiring; Preparation Before Wiring - Delta RPI-H3 Owner's Manual

5. Wiring

5.1 Preparation before Wiring

1. Make sure whether the voltage values, polarities are correct.
2. When grounding of the solar array is necessary, an isolation transformer is
required due to the RPI-H3/RPI-H5 not having a galvanic isolation between
the DC-input and AC-output.
3. The ground fault detection is a fixed internal setting. It always works and
can not be modified.
4. The whole system wiring is shown as in Figure 5-1.
Please refer to Figure 5-1 for the connection. Inverter can accept DC
inputs in parallel (1 MPP tracker/2 parallel inputs).
WARNING！ ！ ！ ！ SHOCK HAZARD
●
!
hazard exists at the output wires or exposed terminals. To
reduce the risk of shock during installation, cover the array
with an opaque (dark) material and ensure that Disconnect
Device is set to OFF before commencing any wiring.
