How to replace Type A Bluetooth with Type B Bluetooth

When the Type A bluetooth is to be changed with type B bluetooth or vice versa;

1. Change the cable coming with Bluetooth. If wire is not changed the bluetooth may be powered up by showing continuously lit red light but it will not communicate with the inverter.
   Color coding for the wire connections to inverter terminals on the Bluetooth cable is the same for both cable types. However internal connections are different.
   

   Wire color	Terminal
   RED	+24V Terminal on the relay board attached to main controller board terminals. (terminals where Type A bluetooth is connected)
   BLACK	GND Terminal on the relay board attached to main controller board terminals. (terminals where Type A bluetooth is connected)
   BLUE / GREEN	rs485+ terminal of the main controller board where the previous blue or green wire connected for type A bluetooth device.
   YELLOW	rs485- terminal of the main controller board where the previous yellow wire connected for type A bluetooth device.

   
   

1. Delete the old bluetooth pairing data from the devices connected or paired before.

Type 1 inverters must have the jumper cable connected between the GND terminal and COM terminal of the control board.
