*1 Case of 100% load ND continuous operation. The heat loss for the optional external devices (input reactor, radio noise reduction filters, etc.) is not
included in the calorific values in the table.
■ Panel designing in consideration of effects of noise
The inverter generates high frequency noise. When designing the control panel, consideration must
begiven to that noise.
Examples of measures are given below.
• Wire so that the power connections and the control connections are separated. Do not place them
in the same conduit, do not run them in parallel, and do not bundle them.
• Provide shielding and twisted wires for control connection.
• Separate the input (power) and output (motor) wires of the power circuit. Do not place them in the
same conduit, do not run them in parallel, and do not bundle them.
• Be sure to ground the inverter grounding terminals.
• Install a surge absorber on any magnetic contactor and relay coils used around the inverter.
• Install radio noise reduction filters if necessary.
