2.8.8 Interne Verschaltung der Jumper
As delivered, the jumpers are set in the “normal position”. With this, the mains filter has its normal effect and
results in a leakage current of > 3.5mA.

2.9 Electrical connection of the control unit
The control terminals are on the front cover of the frequency inverter. The allocation varies according to the
version (SK 500E / 505E / 510E / 520E / 530E / 535E).
Connection terminals:
Plugs, terminals and connectors can be released with a small screwdriver.
Cable cross-section:
0.14 ... 1.5mm
2
, AWG 26-16, stiff or flexible
Control cable:
Lay and shield separately from the mains/motor cables.
For SK 5x0E Section 2.9.2
Internal control voltages:
5V
±
20%
max. 250mA
(Short-circuit proof)
10V
10V, max. 5mA, reference voltage for an external potentiometer
15V
±
20% 150mA max. to supply the digital inputs or a
10-30V incremental rotation encoder
For SK 5x0E Section 2.9.2
External control voltages:
18…30V
800mA min. for the supply of the frequency inverter control unit
Analog output:
0..0.10V
max. 5/20mA, for an external display unit
NOTE
GND/0V is a common reference potential for analogue and digital inputs.
5V / 15V can be collected by several terminals if required. The sum of collected currents must not
exceed 250mA / 150mA.
