CHAPTER 3 WIRING, CONNECTING

3.3 Wiring note

1.Installing / removing the cable or connector must be done after checking the power supply off. 2.Wiring should not have bare cables exposed between connector contacts.

3.Network cables should be fixed without tension. Cables fixed under tension have potential of causing a communication fault by to be removed a connector.

4.A terminating resistor is not built-in the unit. Please provide it.

5.Ensure external emergency stop measures are taken to stop the inverter, in the event of a network fault.

(a)Remove the Power supply of the Inverter when the network master detects a communication fault.

(b)When the master detects a communication fault, turn on the intelligent input terminal which would be allocated (FRS), (RS) and/or (EXT) function.

6.Basic components for construction of Profibus-DP application are shown bellow.

Refer to the master’s description manuals when Profibus-DP Network system comes into operation.
