With the aid of ControlBoxes it is possible to control a frequency inverter with regard to speed and direction of
rotation.
3.1 SK SSX-3A
– Simple Setpoint Box
The "Simple Set Point Box" SK SSX-3A is a
compact control unit with a 4-digit, 7-segment
display, which is primarily intended for fixed
connection to the terminal bar of the frequency
inverter.
The control unit can be used as a handheld or
attached version (wall-mounted). A maximum cable
length of 20m must be observed.
Three operating modes are available, which are
automatically activated according to the connection
variant and the inverter series.
The entire range of functions can be used with the
SK 2xxE series.
If an RS 485 interface is available, the box can also
be used with SK 300E, SK 5xxE, SK 700E and
SK 750E inverters. However, in this case only the
485C mode (control mode via RS 485) is available.

the housing contains 2 holes for optional wall mounting.
