4.3 ParameterBox Installation Version, SK PAR-2E
BU 0750 GB-3311 Subject to technical amendments 59
4.3.1 Electrical connection
The ParameterBox SK PAR-2E is connected via the screw terminal block.
Number Description Terminals
1 + 4.5V ... 30V
with +15V / 60mA
0.14 ... 1.5 mm² 2 GND
3 P+ (A) RS485 +
4 P- (B) RS485 -
Supply voltage
The +15V supply voltage for the ParameterBox can normally be drawn from the connected frequency inverter.
However, if several frequency inverters are linked together, ensure that only one frequency inverter is tapped
for voltage and not several inverters! The frequency inverter with the shortest cable distance to the
ParameterBox should be selected for this.
Communication via RS485
With connection of several frequency inverters in series (as illustrated below), ensure that the ParameterBox is
the first or last participant in the bus system. A termination resistor (approx. 120

) must be provided for the
frequency inverter at the other end of the entire bus system.
