TB1 can be used for incoming RS-232 or RS-485 serial

connection. They cannot be connected at the same time. RS-485

is recommended to reduce undesirable electrical interference.

7. P1 can be used for incoming RS-232 only, although it is optional

and not recommended.

P1 is intended for RS-232 application downloads and RS-485

terminating resistor connection.

See publication 2706-IN007 for more information on RS-485

termination.

8. To maintain NEMA compliance and to prevent EMI emissions,

install hole plugs in any open conduit holes in the power supply

enclosure.

Be sure to place the wires so they are not caught by

screws when replacing the power supply cover, and

also so they do not interfere with fan operation.
