3.4 Details of internal Customer Units SK CU4- …
3.4.1 Mains Unit, SK CU4-24V- …
The mains unit (only permissible for SK 2x5E version) is used to produce the 24V control voltage for the FI
from the available mains voltage (115V/230V/380V/500V). With this, a separate external 24V control voltage
is not required. With SK 2x0E models, a mains unit is integrated at the factory, so that no optional
SK CU4-24V-
… mains unit or no external 24V supply is required.
An analog input is also available for the connection of the potentiometer adapter SK CU4-POT
• Mains unit for 100-240V, SK CU4-24V-123-B
• Mains unit for 380-500V, SK CU4-24V-140-B
• +24V- output voltage
• 1x analog input (e.g. Potentiometer Adapter)
• 1x pulse output
• Status LED = 24V
• Max. permissible continuous current: 420mA
The terminal block of the Customer Unit SK CU4-24V- … is divided into two potential levels.
Compliance with the degree of interference suppression as per Section 8.2 can only be ensures with an ac-
tive mains filter (jumper plugged as shown in the illustration).
To process current setpoint values, the enclosed bag contains a 500Ω resistor, for connection between
terminals 12 and 14. Matching of the relevant input of the frequency inverter is made via parameter (P420).
Setpoint Parameter [Array] Setting
0 … 20mA P420 [-02] or [-03] {26}
4 … 20mA P420 [-02] or [-03] {27}
