Wiring precautions

This section explains Ethernet cable connection and the relevant precautions.
 Handling of the Ethernet cable
• Do not touch the conductors of the cable or the connector on the inverter. Keep the conductors free of dust or dirt. If oil
from your hand, dirt or dust is attached to the core, it can increase transmission loss, arising a problem in data link.
• Check the following:
Is any Ethernet cable disconnected?
Is any of the Ethernet cables shorted?
Are the connectors securely connected?
• Do not use Ethernet cables with broken latches. Doing so may cause the cable to unplug or malfunction.
• The maximum station-to-station distance is 100 m. However, the distance may be shorter depending on the operating
environment of the cable. For details of the cable, contact your cable manufacturer.
 Connecting and disconnecting of the Ethernet cable
Hold the connector part when connecting and disconnecting the Ethernet cable. Pulling a cable connected to the inverter may
damage the inverter or cable, or result in malfunction due to poor contact.
 Network configuration
Check the network configuration before wiring, and perform correct wiring. For example, using ring topology may cause system
failure.
