Protect PV.630 Operating Instructions

The X5 interface can be switched from RS485 to RS232 using jumpers J4 and J5. The factory setting is RS485, i.e. all jumpers are inserted at J4. You have the option of switching the interface to RS232 by reconnecting all jumpers to J5.

Please use a shielded CAN bus cable as the line, e.g. 2 x 0.22 twisted pair Lapp “UNITRONIC-BUS LD”.

Route the CAN bus line from the PV inverter to the remote panel. In a CAN bus network, the ends of the bus must always be termi- nated. A 120 ohm terminating resistor is pre-installed at connector X4 of the CAN bus connection as standard.

Connect the line shield to the housing potential of the INV unit via shield terminal blocks. Openings are provided in the plate of the PV inverter for installing the shield in the connection room area. Remove approx. 20 mm of the sheath at this point.
