===== 2. Installation =====

The side labeled 'CAN-bus BMS' plugs into the battery. The other side, labeled 'VE.Can' must be plugged into either the VE.Can port of the GX device, or the BMS-Can port.

Both port types (VE.Can and BMS-Can) on a GX Device can be configured for use with a CAN-bus BMS connected third party battery.

For configuration, see the manual specific to the brand of battery you are using.

===== 3. Pin-out =====

In some cases it might be needed to make the cable at the location. Find below the pin-outs. Make sure to very carefully test the cable after crimping it. Self-made cables are very often the causes of very hard to diagnose problems.
