Functions
In this operating mode the functions

Control
Display of operating values
are available without restriction and correspond to those of the SimpleBox SK CSX-3H/ -3E.
Connections
Connection to the vertical terminal bar is by means of a 4-
wire cable.
An integrated 270
Ω termination resistor is provided for
RS485 communication.

* Lower baud rates can also be set, however the SK SSX-3A (temporarily) configures the frequency inverter to the setting {3} = 38400Baud, if this was parameterised to the value
<19200Baud. After the mains are switched off at the frequency inverter, the original setting is once again active.

After switching on, the lettering briefly appears in the display
Operation
Control of the Simple Setpoint Box SK SSX-3A in this mode is identical to that of the SimpleBox SK CSX-3H/ -3E
(see Section 2.2).
Control commands (enable/stop/direction of rotation) and setpoints from the box are only recognised by the
frequency inverter if it has not been enabled from other sources (e.g. digital input of the FI). (Priority switching).
This also means that the drive of the source from which it was started must also be set back to Stop.
