1.7 Selecting the Correct Frequency Converter
1.7.1 Introduction
This section explains how to specify and order a VLT 2800.
The frequency converter must be selected on the basis of the present motor current at maximum loading of the unit. The
frequency converter's rated output current I
INV.
must be equal to or greater than the required motor current.
Mains Voltage
VLT 2800 is available for 2 mains voltage ranges:
200-240 V and
380-480 V.
Select whether the frequency converter is connected to a mains voltage of:
1x220-240 V single-phase AC voltage
3x200-240 V 3-phase AC voltage
3x380-480 V 3-phase AC voltage
