NOTE:
To use this function, please contact the manufacturer.
2. Logic interface communication cable (Only for UK)
Logic interface is required by G98 and G99 standard that can be operated by a simple switch or
contactor. When the switch is open circuited the inverter can operated normally. When the
switch is closed, the inverter will reduce it’s output power to zero within 5s.
Pin5 and Pin6 of RJ45 terminal is used for the logic interface connection.
Please follow steps below to assemble DRM RJ45 connector.
Step 1. Insert the network cable into the communication connection terminal of RJ45.
4.6 Assemble Other Cables
1. Battery CAN communication cable

DRM
Step 2. Use the network wire stripper to strip the insulation layer of the communication cable.
According to the standard line sequence of figure 4.16 connect the wire to the plug of RJ45, and
then use a network cable crimping tool to make it tight.
Step 1. Take out the CAN cable (terminal marks ‘CAN' on one end and 'to Battery' on the other end).
Step 2. Unscrew the swivel nut from CAN port.
Step 3. Insert the RJ45 terminal with CAN label into the CAN port, then fasten the swivel nut.
Step 4. Connect the other end to the battery.
Step 3.Connect RJ45 to DRM port (logic interface) .
NOTE:
The CAN cable enables the communication between the inverter and the Li-ion
battery from BYD, PYLON, etc.
Please check for latest model compatibility before installation.

NOTE:
For CAN cable pin 4 (blue) and pin 5 (white-blue) are used for the
communication.
