3G3RV-PDRT2 DeviceNet Communications Card
Mount the DeviceNet Communications Card as shown in the diagram. Detailed precautions are given
below.
• Remove any coating on the footprints of EMC filter, Inverter, and metal mounting plate in order to
ensure a metal contact between grounding faces.
• Attach Option Units to the Inverter.
• Use a shielded cable for the Inverter's power supply line and connect via the EMC-compliant input
noise filter with the shortest cable length possible. Ground the shield at both ends of the cable.
• Use the shortest ground wire possible. For 400-V Inverters, ground the neutral point on the power
supply.
• Use a shielded cable for the cable between the Inverter and motor as well. Keep the cable as short
as possible (20 m max.) and ground the shield at both ends of the cable. It is effective to mount a
clamp filter right next to the Inverter's output terminals.
• Use a conductive cable clamp to directly ground the shield to the ground plate.
• Directly ground the motor frame.
• Use a ZCAT3035-1330 Clamp Filter on the communications cable, wind the cable in a loop around
it, and keep it away from the control panel.
• Use reinforced insulation or double insulation for the DC power supply for communications.
