Installation and Connection

3.5.2 Connection of the control terminal strip

Set value potentiometer
3...10 kÙ
external voltage supply
20...30 VDC ± 0% / 1 A
1) Connect potential equalizing line only if a potential difference of > 30 V exists between
the controls. The internal resistance is reduced to 30 kÙ.
To avoid interferences a separate shielding must be provided for analog and digital control
lines. Depending on the use of the relay outputs, an extra shielding is to be used, too.
In case of inductive load on the relay outputs a protective wiring must be provided (e.g.
free-wheeling diode)!
The control board must always supply by an external voltage. This keeps the control
in operation even if the power stage is switched off. To prevent undefined conditions at
external power supply the basic procedure is to first switch on the power supply and after
that the inverter.
