5.4 DC Connection
The maximum open circuit voltage of the PV Array must not exceed 600Vdc.
CAUTION !
WARNING !
• When undertaking DC wiring, please ensure the correct polarities are connected.
• When undertaking DC wiring, please ensure that the DC isolator switch on the
PV array is OFF.
• When undertaking BAT wiring, please ensure that the BX6.3_DD system is shutdown.
The isolator installed between the PV Array and inverter must meet the rating
