4.2.2 Connection of the Control
In order to prevent a malfunction caused by interference voltage supply on the
control inputs, the following directions should be observed:
- Use shielded/drilled cables
- Lay shield on one side of the inverter onto earth potential
- Lay control and power cable separately (about 10...20 cm apart)
- Lay crossings in a right angle (in case it cannot be prevented)
4.2.3 Digital inputs
Internal voltage supply External voltage supply
4.2.4 Analog inputs
Internal analog set-point setting External analog set-point setting
4.2.5 Outouts
When using inductive consumers at the relay output a protective wiring (i.e. free
wheeling diode) is necessary to protect the relay!
