E.2 Installation

1. Connect the RS485 communication line to RJ45 connector, (see Figure E-1).
2. Check the connections and turn ON the inverter.
3. Table E-1 documents the parameters within the VS1MX that are related to communications:

P35
4. Make connection to the master and other slave devices. The maximum number of drives that can be connected is 31.
Maximum length of communication line is 2300 ft (700m).
E.3 Operation
1. Remove all power from the VS1MX control.
2. Disconnect the motor load from the control (terminals U, V and W). (Do not connect the motor load until stable
communication between the master controller and the inverter are verified.)
3. Verify master controller and the inverter connections.
4. Turn ON the inverter.
5. Start the communications program on the master controller.
6. Verify proper communications and that the VS1MX is controlled as desired.
7. Remove all power from the VS1MX control.
8. Connect the motor load to the control (terminals U, V and W).
9. Turn ON the inverter.
10. Verify proper operation. See Troubleshooting at the end of this section to aid in resolving any remaining problems.
