NoteĹ: Three-pole product needs to be connected to neutral lines (N-line), with the N-line of
main power to the terminal “NUN” and N-line of spare power to “RUN”.
Noteĺ: With AC220V power supply, the controller must not be connected to an external supply
if it is powered internally.
NoteĻ: The maximum voltage for generator output terminals is AC270V/DC30V. At the maximum
voltage, the output current must not exceed 1 A.
5.3 Connection between equipment and its controller
Connection instructions
1. The connection between equipment and its controller is of plug-in type. Take out wires from the
accessory bag, and securely connect them to the screws on both sides of a terminal block according to the
terminal number.
2. Before pulling or inserting wires from or into terminal, make sure the fastening screws on the terminal
block are loosened. Do not force wires into or out of terminal block.
(1) Rotate clockwise for
fastening screws;
(2) Rotate counterclockwise for
removing screws.
