1.1.2 Connection of the
Control
1.1.3 Digital Inputs
1.1.4 Analog Inputs
Connect unused analog
inputs to common, to prevent
set value fluctuations!
1.1.5 Outputs
In order to prevent undefined
conditions during external
power supply, the external
power supply should be
switched on first and then the
inverter.
When using
consumers at the relay output a
protective wiring (i.e. free
wheeling diode) is necessary to
protect the relay!
Installation and Connection
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)
