Installation

■ Switches 1-4

The dipswitch is located on the control card. It is used

for serial communication and external DC supply.

The switching position shown is the factory setting.

Switch 1 has no function.

Switches 2 and 3 are used for terminating an RS

485 interface, serial communication. In the first

and the last frequency converter, switches 2 and

3 must be ON. In the other frequency converter,

switches 2 and 3 must be OFF.

Switch 4 is used if an external 24 V DC supply is required

for the control terminals. Switch 4 separates the

common potential for the internal 24 V DC supply from

the common potential of the external 24 V DC supply.

NB!:

Please note that when Switch 4 is in position

"OFF", the external 24 V DC supply is galvanically

isolated from the frequency converter.
