Using the auxiliary network power connector provides flexibility and convenience in
wiring your application. Be sure to read the following points to avoid any problems:
• Make sure the polarity of the power supply connection is correct. If in doubt, check
continuity between the two connectors to ensure the polarity is maintained.
• The power supply must provide proper output current limit and fusing for the network
device load.
• Remember that you must open the front door panel of the inverter to connect or
disconnect wiring to the auxiliary network power connector. If power has been
connected, wait five minutes after powerdown and verify the Power LED is OFF
before opening the inverter front door panel.
