 Panel designing taking into consideration the effects of noise
The inverter generates high frequency noise. When designing the control panel setup, consideration must be
given to that noise. Examples of measures are given below.
 Wire so that the main circuit wires and the control circuit wires are separated. Do not place them in the
same conduit, do not run them parallel, and do not bundle them.
 Provide shielding and twisted wire for control circuit wiring.
 Separate the input (power) and output (motor) wires of the main circuit. Do not place them in the same
1
conduit, do not run them parallel, and do not bundle them.
 Ground the inverter grounding terminals (
 Install surge suppressor on any magnetic contactor and relay coils used around the inverter.
 Install noise filters if necessary.
 To comply with the EMC directives, install the optional EMC plate and fix the shield to it.
 Install EMC plate and use shielded wires.
