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.

VIII. Troubleshooting of common faults
Common faults
No display on controller
The main (spare) power
indication lamp on controller
panel is not ON. The switch is at
the main (spare) power position,
and fails to act.
Failure of automatic switch
In automatic mode, the switch
fails to act upon a change to
power supply
Upon inputting a fire signal
1) The switch fails to act
2) The switch fails to return to the
previous status after its action.
Cuase
1) The controller is not
energized.
2) The terminals of connecting
wire are not securely attached
to both the transfer switch and
controller.
1) The terminals of connecting wire
are not securely attached to both
the transfer switch and controller.
2) The wires connected with the
transfer switch are loose at the
interface or come off.
The manual/auto mode is not
set correctly.
1) Both power supplies fail
2) The wires show poor
interface contact or come off
1) The fire signal wire is
improperly connected
2) The switch is set at
“manual” position.
Troubleshooting
1) Push the controller’s “power” button on
transfer switch to switch to “I” position
2) Reconnect the wire terminals as per the
steps given in Section 5.3, and secure
fastening screw
1) Reconnect the wire terminals as per the
steps given in Section 5.3, and secure
fastening screw
2) Fasten all wires connected with the switch
Push “manual/auto” button on the panel of
controller SU603 and switch to “auto” status,
in which the “auto” light is ON.
1) Provide normal main and spare power
