Do not exceed the maximum rotation speed of the machine.

Figure 10. EC-C1200

Figure 11. Schematic of the inverter powerstage

The main machine power driving parameters are shown in the machine rating plate. For

more information, please contact Danfoss representative.
You can connect one of the temperature signals (from the low voltage connector) to the

temperature surveillance pin in the inverter and make sure that the inverter has the machine

temperature protection feature activated.
