4.3 Preparation before Wiring
1. Ensure voltage values and polarities are correct.
2. Ensure PV Switch is set to OFF, and BX6.3_DD system is shutdown.
3. When grounding the solar array positive or negative terminal, an isolation
transformer is required due to the inverter has no galvanic isolation between
the DC-input and AC-output.
4. Please refer to Figure 4-4 for connections. Inverter can accept DC inputs in
parallel.
5. According to IEC 62109-2, the PV modules need to have an IEC 61730 Class
A rating.

WARNING! SHOCK HAZARD
When the photovoltaic array is exposed to light, it supplies a DC voltage to the
Inverter, a shock hazard may exist due to output wires or exposed terminals.
To reduce the risk of shock during installation, cover the array with an opaque
(dark) material and ensure that the Disconnect Device in the inverter is set to OFF
before commencing any wiring.
