DRM CONNECTION

DRM is provided to support several demand response modes by emitting control signals as 

below. 

Note: Only PIN6(DRM0) is available now, and other PIN functions are being developed.

DRM CONNECTION STEPS

Please refer to BMS connection steps (page32) for DRM connection. Please kindly noted 

the PIN definition and port position will be slightly different.
