Electrical Connection SK …-3E
The parameter boxes SK CSX-3E and SK PAR-3E are only
connected to a frequency inverter via the RJ12 socket. This
connection also provides the power supply to the box.
A termination resistor (220
) for the RS485 bus system is
integrated into the module. Therefore the ParameterBox should
only be connected as the first or last participant.
In contrast to the handheld version SK PAR-3H, connection of
the SK PAR-3E ParameterBox to a PC is not possible.
Connection to the particular frequency inverter is made via the
RJ12 connection sockets on the device. The SimpleBox
SK CSX-3E can only communicate with frequency inverters.
The contact assignment of the RJ-12 connection on the parameter box is as follows:
