Communication (Comm) loss error code 4008 with PM870 in System Manager Software (SMS) 4.0 or 4.0.1

Error code 4008 means the Square D ID is not valid for the device type. Check the version of SMS. The 4008 error could be a result of SMS being an older version that does not support the PM870 meter. The PM870 meter will only communicate with SMS v4.0.2 or newer.
