Notes:
- Requires a Probus DP option card (EXP-PDP-BDI/VDI) for each inverter.
- Requires 24Vdc power supply. Size power supply based on the number of inverters on the network.
- A maximum of 31 inverters can be connected to the network. Terminating resistors of 220 ohm must be
installed at both end of the network.
