1) 2-wire RS485

The 2-wire RS485 device on the operation panel and the 4-wire RS485 device on the control circuit terminal block are intended for data communications between inverters. To use an optional part for the RS485 device, it should be connected to the communication connector (RJ45) on the operation panel. Through the 2-wire RS485 device! and a USB device (optional), the inverter can be linked to a computer.

!Here are the parts optionally available for the 2-wire RS485 device.

•Optional USB-to-Serial conversion unit (Model: USB001Z)

Inverter-to-RS485/USB device interconnect cable (Model: CAB0011 (1m), CAB0013 (3m), CAB0015 (5m)) RS485/USB device-to-computer interconnect cable. Use a commercially available USB1.1 or 2.0 cable. (Type: A-B, Cablelength: 0.25~1.5m)

•Optional LED Remote Keypad (Model: RKP002Z)

Communication cable (Model:CAB0011 (1m), CAB0013 (3m), CAB0015 (5m))

•Optional LCD Remote Keypad (Model: RKP004Z)

LCD special cable (Model:CAB0071 (1m), CAB0073 (3m), CAB0075 (5m), CAB00710 (10m))

Note: Do not connect the cable (CAB0011, 0013 or 0015) from the communication device to the optional LCD Remote Keypad. Or the inverter or the optinol LCD Remote Keypad could be damaged.
